vRealize Infrastructure Navigator: Complete Guide to Application Dependency Mapping

Infrastructure management becomes difficult when an organization runs dozens or hundreds of virtual machines without knowing how they communicate with one another. Understanding these connections is essential for troubleshooting, planning migrations, improving security, and maintaining reliable IT services. vrealize infrastructure navigator was developed to address this challenge by helping VMware administrators discover applications, identify communication between virtual machines, and understand dependencies across virtualized environments.

Although this technology is now considered a legacy VMware solution, its approach to application discovery and infrastructure dependency mapping remains relevant. Many IT professionals still encounter it when maintaining older VMware environments, reviewing historical infrastructure documentation, or planning modernization projects.

This guide explains what the platform was designed to do, how its architecture worked, how administrators used it, its major benefits and limitations, and what organizations should consider when replacing it with modern infrastructure monitoring and discovery solutions.

What Is vRealize Infrastructure Navigator?

vRealize Infrastructure Navigator, commonly abbreviated as VIN, was a VMware application discovery and dependency mapping solution designed for virtualized infrastructure.

It helped administrators understand the relationships between virtual machines and the applications and services running inside them. Rather than relying entirely on manually maintained infrastructure diagrams, administrators could use the platform to discover communication patterns and visualize dependencies within their VMware environments.

Its primary purpose was to provide application awareness at the infrastructure level.

For example, consider an organization running an online shopping application. Its infrastructure might contain:

A web server handling customer requests.
An application server processing business operations.
A database server storing customer and transaction information.
An authentication service managing user access.
A backup server protecting important information.

Although these systems operate as separate virtual machines, they work together to deliver one application.

Without dependency mapping, an administrator might understand what each virtual machine does individually but have difficulty identifying how the entire application operates.

VIN helped make these relationships easier to understand through application dependency maps.

The Main Purpose of Infrastructure Navigator

The solution was designed around several important infrastructure management requirements:

Application discovery: Identify applications and services operating within virtual machines.
Dependency mapping: Discover communication relationships between virtual machines.
Infrastructure visibility: Give administrators a clearer picture of application-related infrastructure.
Application grouping: Organize connected virtual machines into logical application groups.
Operational planning: Support infrastructure changes by helping administrators understand which systems depend on others.

Its value was not simply displaying virtual machines. It helped connect infrastructure information with application-level relationships.

This distinction is important because a virtual machine inventory tells administrators what exists, while dependency mapping helps explain how those resources work together.

How vRealize Infrastructure Navigator Worked

Understanding the operating process is important because the platform combined virtual infrastructure information with application-level discovery.

It was deployed as a virtual appliance inside a VMware environment and integrated with vCenter Server. Administrators could then access its functionality through the vSphere Web Client.

The discovery process involved several stages.

1. Deploying the Virtual Appliance

The first step was deploying the Infrastructure Navigator appliance into the existing VMware environment.

The appliance provided the services required for application discovery and dependency mapping.

During deployment, administrators needed to consider:

Available computing and memory resources.
Compatibility with the installed vCenter Server version.
Network connectivity between the appliance and managed infrastructure.
Required communication ports.
Appropriate administrative permissions.
VMware Tools availability on monitored virtual machines.

The installation process was designed for VMware environments of its supported generation. It should not be treated as a deployment procedure for modern vSphere releases.

2. Connecting With vCenter Server

After deploying the appliance, administrators configured its connection with vCenter Server.

This integration allowed the platform to access relevant virtual infrastructure information and present application relationships within the familiar VMware management interface.

The connection also provided administrators with a centralized way to inspect virtual machines and their associated application dependencies.

A dedicated service account with appropriate permissions was a sensible administrative practice. Using an individual administrator’s account for permanent service access would make credential management and auditing more difficult.

3. Discovering Applications and Services

One of the platform’s important capabilities was identifying services running inside virtual machines.

It examined information about application services, processes, and network communication to help identify relationships between infrastructure resources.

For example, a database service might communicate with an application server over a particular network port.

The discovery information helped administrators understand that the two virtual machines were not independent resources. They were connected parts of a larger application environment.

Discovery quality depended on the available information, service definitions, guest access, and whether the relevant services were active.

Administrators therefore needed to treat discovered information as operational evidence rather than an unquestionable record of every application relationship.

4. Mapping Application Dependencies

Once relevant services and communication relationships were identified, the platform could present them through a visual dependency map.

A typical application map could show:

Virtual machines hosting application components.
Services identified on those machines.
Connections between different infrastructure resources.
Relationships between application tiers.
External systems communicating with the virtual environment.

These relationships helped administrators understand how an application was distributed across the infrastructure.

For instance, if an application server communicated with two database servers, the map could help reveal those connections and support further investigation.

This was especially useful when documentation was incomplete or when infrastructure had changed over time.

5. Creating Application Groups

Administrators could organize related virtual machines into logical application groups.

This made it easier to manage a multi-tier application as a connected service rather than treating every virtual machine as an isolated resource.

Consider a business application containing:

Two web servers.
Three application servers.
One primary database server.
One reporting database server.

An administrator could organize the relevant resources into an application group representing the business application.

This structure improved infrastructure understanding and supported operational planning.

6. Integrating With vRealize Operations Manager

Another important aspect was its relationship with VMware’s broader management ecosystem.

VIN information could be integrated with vRealize Operations Manager through the appropriate management pack and configuration.

This allowed administrators to bring application topology information into operational dashboards.

The distinction between these products is important.

Infrastructure Navigator focused on discovering and mapping application dependencies. vRealize Operations Manager provided broader infrastructure monitoring, performance analysis, capacity information, and operational management.

Together, these capabilities helped administrators connect application relationships with infrastructure health information.

Key Features of vRealize Infrastructure Navigator

The platform was built around application awareness rather than general-purpose infrastructure monitoring.

Its features addressed specific challenges faced by administrators managing complex VMware environments.

1. Automated Application Discovery

Manual application documentation can become outdated quickly.

A server may be replaced, an application component may move to another virtual machine, or a new service may be introduced without the infrastructure documentation being updated.

Automated discovery helped reduce this dependency on manual records.

Administrators could use the platform to identify application services and investigate their relationships with other virtual machines.

However, automated discovery did not eliminate the need for verification. Unknown services, unusual ports, and applications with incomplete discovery information could still require administrator attention.

2. Application Dependency Visualization

Visual dependency mapping was one of its most useful capabilities.

Instead of reviewing multiple spreadsheets or configuration documents, administrators could inspect a graphical representation of application relationships.

This was particularly useful for understanding multi-tier applications.

For example:

Application component	Main responsibility
Web server	Receives user requests
Application server	Processes business logic
Database server	Stores application information
Authentication service	Verifies user identities
Backup server	Protects application data

The dependency map helped connect these individual components into a broader application picture.

3. Service Identification

Understanding which services were running inside a virtual machine was essential for identifying application relationships.

A virtual machine could host multiple services, each communicating with different infrastructure components.

Service identification helped administrators investigate:

Which services were active.
Which ports were associated with communication.
Which virtual machines were interacting.
Which services might belong to a particular application.

Where automatic identification was incomplete, administrators could use available service-definition capabilities to improve the interpretation of discovered information.

4. Multi-Tier Application Understanding

Modern business applications rarely operate through a single server.

They commonly use multiple layers, each responsible for a different function.

For example, an enterprise resource planning system might include:

A presentation layer.
An application processing layer.
A database layer.
An authentication component.
Reporting and integration services.

Infrastructure Navigator helped administrators understand how these components were distributed across virtual machines.

This information was useful when troubleshooting application failures or planning infrastructure changes.

5. Application Grouping

Application grouping provided a more organized way to represent related virtual machines.

Instead of managing every virtual machine independently, administrators could create logical groups representing complete applications.

This was useful for:

Identifying application-related resources.
Organizing infrastructure inventories.
Understanding application boundaries.
Supporting migration planning.
Improving communication between infrastructure and application teams.

The feature was particularly relevant in large environments where different business applications shared the same VMware infrastructure.

6. Integration With Existing VMware Management Tools

The platform’s integration with vCenter Server reduced the need to switch between completely separate management interfaces.

Administrators could work with application dependency information in the context of their existing virtual infrastructure.

Its integration with vRealize Operations Manager also helped connect discovered application relationships with broader infrastructure management information.

This was valuable because infrastructure performance and application dependencies are closely related.

A virtual machine experiencing resource pressure may affect an application component, which could then influence other connected services.

Understanding these relationships makes troubleshooting more structured.

Major Benefits of Using Infrastructure Dependency Mapping

The value of this technology becomes clearer when considering the operational problems it was designed to address.

Better Infrastructure Visibility

Large VMware environments can contain hundreds of virtual machines.

As environments grow, it becomes increasingly difficult to maintain an accurate understanding of every application and its infrastructure requirements.

Dependency mapping helps administrators move beyond basic virtual machine inventories.

It provides a relationship-based view of infrastructure.

This is useful when an administrator needs to answer questions such as:

Which virtual machines support this business application?
Which services communicate with the database?
What systems might be affected by a server shutdown?
Which virtual machines belong to the same application?
Are there undocumented connections between systems?

Having this information available can improve the quality of infrastructure decisions.

More Effective Troubleshooting

Application problems are not always caused by the server displaying the error.

A web application may fail because its database connection is unavailable. A login problem may originate from an authentication service. A reporting application may stop working because another internal service has become unreachable.

Without dependency information, administrators may spend significant time investigating unrelated infrastructure components.

A dependency map provides a starting point for tracing these relationships.

For example, suppose users cannot access an internal business application.

An administrator can investigate:

Whether the web server is running.
Whether the application server is available.
Whether the database service is responding.
Whether the expected communication path exists.
Whether another dependent service is experiencing problems.

This does not automatically identify the root cause, but it helps narrow the investigation.

Safer Infrastructure Changes

Infrastructure changes can introduce unexpected application problems.

Consider an administrator who wants to shut down an old virtual machine because it appears unused.

That machine may still host a service required by another application.

If the dependency is undocumented, shutting down the server could interrupt an important business process.

Application mapping helps identify possible relationships before changes are made.

Administrators can use this information to investigate the impact of:

Virtual machine removal.
Server consolidation.
Network segmentation.
Infrastructure upgrades.
Application migrations.
Resource redistribution.

A dependency map should be treated as one source of evidence during change planning, not as a replacement for application-owner approval or formal testing.

Improved Migration Planning

Application migration is more complicated than moving virtual machines from one host to another.

A successful migration requires understanding how application components communicate and which services must remain available.

For example, moving a web server without considering its application server or database connections could create unnecessary downtime.

Dependency mapping helps identify these relationships before migration activities begin.

Administrators can use the information to:

Identify application components.
Group related virtual machines.
Understand communication requirements.
Prioritize migration sequences.
Identify external dependencies.
Validate the target environment.

This is especially useful when migrating legacy applications with limited documentation.

Better Collaboration Between IT Teams

Infrastructure administrators, application developers, security professionals, and database administrators often work with different views of the same environment.

An infrastructure administrator may think in terms of virtual machines and hosts.

A developer may focus on application services and APIs.

A database administrator may be concerned with database availability and connections.

Dependency maps help create a shared understanding of how these components relate to one another.

This can reduce misunderstandings during troubleshooting and infrastructure planning.

Real-World Applications of vRealize Infrastructure Navigator

The following examples illustrate practical situations where application dependency mapping can provide value. They are representative operational scenarios, not claims about specific customer deployments.

1. Enterprise Application Management

Large organizations often operate multiple enterprise applications on shared VMware infrastructure.

These applications may contain separate web, application, database, authentication, and integration components.

Managing them without accurate dependency information can become difficult.

Infrastructure Navigator helped administrators understand which virtual machines were associated with particular applications.

For example, a company operating an internal finance application could use application grouping to organize its related virtual machines.

When planning a server upgrade, administrators could review the application structure before making changes.

This made it easier to identify which systems required additional testing.

2. Data Center Migration

Data center migration requires a detailed understanding of application relationships.

Moving virtual machines without understanding their communication requirements can result in broken application connections.

Consider a company migrating its internal customer management platform.

The application might use:

A web server located in one cluster.
An application server in another cluster.
A database hosted on separate virtual infrastructure.
An authentication service maintained by another team.

Dependency information helps identify these connections.

Administrators can use the discovered relationships to prepare migration groups and check whether the destination environment supports the required communication paths.

This approach reduces the risk of overlooking important application components.

3. Infrastructure Consolidation

Organizations frequently consolidate infrastructure to reduce operating costs and improve resource utilization.

During consolidation, administrators may identify virtual machines that appear redundant or unnecessary.

However, removing a virtual machine without understanding its role can affect connected applications.

Dependency mapping can help reveal whether a particular machine communicates with other application components.

Before removing a server, administrators should combine dependency information with:

CPU and memory utilization.
Storage activity.
Application ownership records.
Network traffic information.
Business requirements.
Backup and recovery policies.

This creates a more reliable basis for consolidation decisions.

4. Security and Network Segmentation

Network segmentation is an important security practice.

It involves separating systems into different network zones based on their roles, trust levels, and communication requirements.

However, segmentation can disrupt applications when administrators do not understand existing connections.

For example, a database server may need to communicate with several application servers over specific ports.

If these connections are blocked without proper analysis, application functionality may be affected.

Application dependency mapping can help identify communication relationships that require further security review.

Administrators can use this information to develop more informed firewall and segmentation policies.

It is important to understand that VIN was not a complete security monitoring or threat detection solution. Its dependency information was an input into security planning, not a substitute for dedicated security controls.

5. Disaster Recovery Planning

Disaster recovery planning requires more than identifying which virtual machines need backups.

Organizations must understand the relationships between application components and the order in which services should become available.

For example, a multi-tier application may require its database to become operational before the application server can process requests.

The web layer may then need to connect to the application layer before users can access the service.

Dependency information can help administrators document these relationships and prepare recovery procedures.

However, discovery alone does not create a disaster recovery plan.

Organizations must also test recovery processes, verify data consistency, define recovery time objectives, and establish recovery point objectives.

6. Legacy Application Documentation

Older applications often remain operational long after their original developers have left an organization.

Documentation may be incomplete, and administrators may not know why certain virtual machines communicate with one another.

This creates problems during maintenance and modernization.

Dependency discovery can help reconstruct parts of the application’s infrastructure relationships.

Administrators can use the information as a starting point for creating updated documentation.

The resulting records should be reviewed with application owners because network communication does not always reveal the full business purpose of a service.

Limitations and Challenges of vRealize Infrastructure Navigator

Although the platform provided useful application awareness, it also had limitations that organizations needed to understand.

These limitations are particularly important when evaluating the technology today.

1. Limited Compatibility With Modern VMware Environments

The platform was developed for an earlier generation of VMware infrastructure.

Its supported environment included older vCenter Server and vSphere configurations. The 5.8.x product generation is now obsolete.

Organizations should not assume that an older appliance will operate correctly with current VMware infrastructure.

Compatibility should always be verified against the relevant historical product documentation and infrastructure versions.

2. Legacy Product and Support Status

One of the most important considerations is its lifecycle.

The vRealize Infrastructure Navigator 5.8.x product family reached its end of general support on September 26, 2017, according to the historical VMware product lifecycle information.

This means organizations should not consider it a currently maintained infrastructure discovery solution.

An unsupported product may lack:

Current security updates.
Compatibility improvements.
New application discovery capabilities.
Bug fixes.
Regular technical support.

This creates operational and security concerns, particularly when the appliance is connected to important production infrastructure.

Organizations still using it should review their exposure and develop a migration or retirement plan.

3. Dependence on VMware Infrastructure

The solution was closely integrated with the VMware ecosystem.

This provided convenience for administrators managing supported VMware environments, but it also limited its usefulness in heterogeneous infrastructure.

Organizations using multiple virtualization platforms or public cloud services may need broader discovery capabilities.

For example, a business operating VMware alongside Microsoft Hyper-V, cloud-hosted workloads, and container platforms requires a tool that can provide visibility across those environments.

A VMware-focused legacy appliance cannot be assumed to provide that level of coverage.

4. Discovery Accuracy Was Not Guaranteed

Automated application discovery reduces manual effort, but it does not eliminate uncertainty.

Some applications use dynamic ports, encrypted connections, unusual service configurations, or temporary communication patterns.

These characteristics can make complete discovery difficult.

An administrator may also encounter services that cannot be automatically identified.

In such cases, service definitions and manual investigation may be necessary.

The best approach is to validate discovered relationships with application owners, configuration records, and network information.

5. Limited Modern Observability Capabilities

Application dependency mapping and application observability are related, but they are not identical.

Dependency mapping focuses on identifying relationships between infrastructure components.

Modern observability platforms can provide additional information, including:

Application response times.
Distributed request traces.
Error rates.
Application performance indicators.
Log analysis.
Real-time service health.
User experience measurements.

VIN was not designed to provide the complete functionality of today’s application observability platforms.

Organizations requiring deeper application performance analysis should evaluate a modern solution.

6. Maintenance and Administrative Complexity

Even when a legacy appliance continues operating, maintaining it can become increasingly difficult.

Administrators may need to investigate old credentials, outdated certificates, compatibility issues, and undocumented configurations.

They may also have difficulty obtaining installation packages and historical support information.

These challenges can increase the time required to maintain an environment that no longer receives normal product updates.

For this reason, continuing to operate an unsupported appliance should be an intentional, documented decision rather than an assumption that it remains safe because it still works.

Is vRealize Infrastructure Navigator Still Available and Supported?

No. It is a discontinued legacy VMware product and should not be treated as a supported option for new infrastructure deployments.

Its 5.8.x family reached the end of general support in September 2017.

This distinction matters because some administrators encounter the product in older technical articles, VMware training material, infrastructure diagrams, and historical deployment guides.

The presence of installation instructions online does not mean the product is still maintained or compatible with current infrastructure.

Why Was the Product Important Historically?

VIN addressed a genuine infrastructure management problem.

As virtual environments expanded, administrators needed better ways to understand relationships between applications and virtual machines.

Traditional infrastructure inventories provided information about virtual machines, hosts, and clusters, but they did not always explain how business applications depended on those resources.

Application discovery helped bridge this gap.

Its approach also reflected a broader shift toward application-aware infrastructure management.

Instead of focusing exclusively on hardware and virtual machines, IT teams increasingly needed to understand services, dependencies, and business application relationships.

Although the original product is discontinued, this requirement has not disappeared.

Should Existing Users Continue Running It?

Organizations that still have an installation should begin with a technical assessment.

They should identify:

Which vCenter Server environment hosts the appliance.
Whether the appliance is still actively collecting information.
Which teams depend on its application maps.
Whether its discovered information is still accurate.
Whether the appliance has access to sensitive infrastructure.
Which modern solution could replace its functionality.

The next step should be documenting important application relationships before retiring the appliance.

This prevents useful infrastructure knowledge from disappearing during modernization.

Alternatives to vRealize Infrastructure Navigator

There is no single replacement that reproduces every historical VIN capability in exactly the same way.

The correct alternative depends on the organization’s requirements.

Some organizations need basic application dependency mapping. Others require network traffic visibility, infrastructure discovery, service mapping, or comprehensive application observability.

The following solutions address different parts of this requirement.

1. VMware Aria Operations for Networks

VMware Aria Operations for Networks, formerly known as vRealize Network Insight, is relevant when the main requirement involves network visibility and communication analysis.

It helps organizations investigate network traffic, connectivity, network relationships, and infrastructure communication patterns.

Its capabilities can support:

Network dependency investigation.
Traffic analysis.
Connectivity troubleshooting.
Network security planning.
Application communication analysis.

It should not be considered an identical replacement for VIN.

The two products address overlapping but different infrastructure management needs.

For organizations primarily interested in understanding communication between workloads, network analytics may be an appropriate direction.

2. VMware Aria Operations

VMware Aria Operations was developed to provide broader infrastructure monitoring and operational management.

It focuses on areas such as:

Infrastructure performance.
Capacity management.
Resource utilization.
Operational visibility.
Infrastructure health.
Performance troubleshooting.

It is relevant when organizations need to understand the condition and performance of their VMware infrastructure.

However, administrators should verify the exact capabilities and licensing of the current offering rather than assume that every historical VIN feature is included.

VMware’s product naming and packaging have also changed over time. Aria Operations is part of the wider VMware Cloud Foundation management portfolio, so current availability should be checked against the applicable offering.

3. ServiceNow Discovery and Service Mapping

ServiceNow Discovery and Service Mapping are relevant when an organization wants to build and maintain an application-oriented configuration management database.

These capabilities help identify infrastructure components and establish relationships between technical resources and business services.

Potential use cases include:

Infrastructure inventory management.
Application service mapping.
Configuration management.
Change impact analysis.
IT service management.
Service dependency documentation.

This approach can be particularly useful for organizations that want infrastructure information connected with their IT service management processes.

4. Dynatrace

Dynatrace is a modern observability platform focused on application performance and service relationships.

It can help organizations understand how applications operate across complex environments.

Its capabilities include application monitoring, distributed tracing, service discovery, and performance analysis.

It may be appropriate when the requirement goes beyond infrastructure dependency mapping and includes application behavior.

For example, an organization investigating slow application responses may need to understand not only which servers communicate but also where requests spend time during execution.

5. Datadog

Datadog provides infrastructure monitoring and application observability capabilities.

It can help teams monitor services, infrastructure resources, logs, and application performance from a centralized platform.

Organizations may consider it when managing distributed environments involving cloud services, containers, and traditional infrastructure.

Its suitability depends on the required integrations, monitoring coverage, licensing, and operational requirements.

6. Device42

Device42 focuses on infrastructure discovery, asset information, and dependency mapping.

It can help organizations understand relationships between infrastructure components and maintain more accurate IT inventories.

It is worth evaluating when the primary requirement is infrastructure documentation and application dependency visibility.

Comparison of Potential Alternatives

Platform	Main focus	Suitable requirement
Aria Operations for Networks	Network visibility	Workload communication analysis
Aria Operations	Infrastructure operations	Performance and capacity monitoring
ServiceNow Discovery	IT discovery	Infrastructure inventory and service mapping
Dynatrace	Application observability	Application performance and tracing
Datadog	Cloud observability	Distributed infrastructure monitoring
Device42	Infrastructure discovery	Dependency mapping and documentation

The best choice depends on the problem being solved.

A company replacing VIN for network communication analysis may need a different product from an organization replacing it for application inventory and service mapping.

How to Plan a Migration From Legacy Infrastructure Navigator

Replacing a discontinued infrastructure tool requires more than installing a new application.

The organization must understand which information is valuable, how that information is currently used, and what capabilities the replacement must provide.

A structured migration process can reduce operational disruption.

Step 1: Audit the Existing Environment

Begin by reviewing the current appliance and its relationship with vCenter Server.

Record the following information:

Appliance version.
vCenter Server version.
Connected virtual machines.
Configured application groups.
Discovered services.
Existing service definitions.
Administrative accounts.
Network connections.
Current usage by IT teams.

This audit establishes the scope of the migration.

It also helps identify whether the appliance is still providing useful information.

Step 2: Document Important Application Dependencies

Before removing the existing platform, document the application relationships that matter to the business.

Focus on critical applications first.

For each application, identify:

Application owner.
Related virtual machines.
Important services.
Database dependencies.
Network communication requirements.
External service connections.
Recovery requirements.

Do not rely entirely on old dependency maps.

Validate important relationships through application teams and other technical records.

Step 3: Define Replacement Requirements

Different organizations need different capabilities.

A replacement assessment should begin with operational requirements rather than product names.

For example, consider these questions:

Do we need automatic application discovery?
Do we need network traffic analysis?
Do we need service dependency mapping?
Do we need cloud infrastructure coverage?
Do we need distributed tracing?
Do we need configuration management?
Do we need integration with an existing ITSM platform?

Answering these questions helps narrow the available options.

Step 4: Evaluate Potential Replacement Platforms

Compare candidate products using practical requirements.

A useful evaluation should consider:

Supported infrastructure platforms.
Discovery methods.
Application mapping capabilities.
Monitoring coverage.
Security and access controls.
Integration options.
Licensing requirements.
Operational complexity.
Vendor support.
Total cost of ownership.

A product with many features is not automatically the best choice.

The most useful solution is one that addresses the organization’s actual operational requirements without introducing unnecessary complexity.

Step 5: Run a Controlled Proof of Concept

Before migrating the entire environment, test the replacement with a limited number of applications.

Choose applications with different characteristics.

For example:

A simple two-tier application.
A multi-tier enterprise application.
An application with external dependencies.
A legacy application with limited documentation.

Evaluate whether the replacement identifies the expected infrastructure relationships.

Compare its findings with application-owner records and network configurations.

This testing helps identify discovery gaps before the platform is deployed more widely.

Step 6: Validate the Results

Discovery information should be reviewed for completeness and accuracy.

Check whether:

Important application components are visible.
Expected communication relationships are identified.
Unrelated systems are incorrectly grouped.
Critical external dependencies are represented.
Application owners agree with the mapped architecture.
Security teams can interpret the discovered communication paths.

This validation stage is essential.

An attractive topology diagram is not necessarily an accurate representation of the production application.

Step 7: Retire the Legacy Appliance Carefully

Once the replacement has been tested and accepted, plan the retirement of the old appliance.

Before shutting it down:

Export or preserve useful documentation where possible.
Confirm application owners have reviewed critical dependencies.
Remove unnecessary credentials.
Review firewall rules.
Update infrastructure documentation.
Confirm monitoring coverage in the replacement platform.
Follow the organization’s change management process.

The final retirement should be documented so future administrators understand when and why the legacy system was removed.

Best Practices for Application Dependency Mapping

Whether an organization uses a historical VMware solution or a modern discovery platform, certain practices help improve the quality of dependency information.

Keep Application Documentation Updated

Application architecture changes over time.

New services are introduced, virtual machines are replaced, and infrastructure components move between environments.

Documentation should reflect these changes.

Assign ownership of application records and review them periodically.

Validate Automatically Discovered Relationships

Automated discovery is valuable, but it should not be treated as perfect.

Validate important connections with application owners and network administrators.

Pay particular attention to critical business applications and services with external dependencies.

Separate Business Applications From Infrastructure Resources

A virtual machine is an infrastructure resource.

An application is a collection of components that work together to provide a business function.

These concepts should not be confused.

A single application may use multiple virtual machines, and a single virtual machine may support multiple application services.

Accurate documentation should reflect this complexity.

Prioritize Critical Applications

Not every application requires the same level of investigation.

Start with systems that support important business operations.

Examples include:

Financial applications.
Customer management platforms.
Enterprise resource planning systems.
Authentication services.
Payment processing applications.
Business-critical databases.

Prioritizing these systems provides a clearer return on the time spent improving dependency information.

Review Network Communication Regularly

Application communication patterns can change.

Regular reviews help identify outdated dependencies, unexpected connections, and infrastructure relationships that require investigation.

This information can support security reviews and infrastructure modernization.

Maintain a Clear Ownership Structure

Every critical application should have an identifiable technical or business owner.

Ownership helps ensure that discovered relationships are interpreted correctly and that infrastructure changes are reviewed by the appropriate people.

Without ownership, dependency documentation can quickly become another outdated IT record.

Understanding the Difference Between Dependency Mapping and Observability

These two concepts are often discussed together, but they solve different problems.

Dependency mapping explains which infrastructure components and services are connected.

Observability helps teams understand the internal behavior and performance of systems through telemetry such as metrics, logs, and traces.

Consider an application that has become slow.

A dependency map might show that its web server communicates with an application server and a database.

Observability data can provide additional details:

Whether requests are taking longer than expected.
Whether database queries are slow.
Whether an application service is generating errors.
Which part of a request is consuming the most time.
Whether the issue affects all users or a specific service.

Both approaches are useful, but they are not interchangeable.

Organizations modernizing their infrastructure management should determine whether they need relationship discovery, performance monitoring, or both.

This distinction helps avoid choosing a replacement based on a product’s marketing description rather than its actual capabilities.

Frequently Asked Questions About vRealize Infrastructure Navigator

The appropriate choice depends on whether an organization needs network visibility, infrastructure discovery, dependency mapping, or application observability.

6. Can vRealize Infrastructure Navigator be used with modern vSphere versions?

Organizations should not assume compatibility with modern vSphere releases. The product was designed for older VMware environments and is no longer maintained. Any existing deployment should be assessed for compatibility, security exposure, and migration requirements before continued use.

Conclusion

vRealize Infrastructure Navigator addressed an important challenge in VMware infrastructure management: understanding how applications and services depend on virtual machines.

Its application discovery, service identification, dependency visualization, and application grouping capabilities helped administrators develop a clearer picture of their virtual environments.

These capabilities were particularly useful for troubleshooting, infrastructure consolidation, data center migrations, security planning, and application documentation.

However, the product’s discontinued status and September 2017 end-of-general-support milestone make it unsuitable as a new production solution. Organizations that still encounter it in older environments should focus on preserving useful application knowledge and planning a transition to supported technology.

The broader lesson remains relevant: effective infrastructure management requires more than knowing which virtual machines exist. Administrators also need to understand how those machines communicate, which applications depend on them, and what could happen when infrastructure changes.

Application dependency mapping continues to be an important part of building reliable, secure, and manageable IT environments.
