Management applications leverage a traditional 3-tier client/server architecture with a presentation tier (user interface), functional process logic tier, and data tier. The microsegmentation use case includes only vRealize Log Insight, though other applications such as vRealize Automation can be added as the design grows to a full software-defined data center.

Place vRealize Log Insight onan application virtual network.

Access to the management applications is only through published access points.

The application virtual network is fronted by an NSX Edge device for load balancing and the distributed firewall to isolate applications from each other and external users. Direct access to application virtual networks is controlled by distributed firewall rules.

Having software-defined networking based on NSX in the management stack makes all NSX features available to the management applications.

This approach to network virtualization service design improves security and mobility of the management applications, and reduces the integration effort with existing customer networks.

Certain configuration choices might later facilitate the tenant onboarding process.

  • Create the primary NSX ESG to act as the tenant PLR and the logical switch that forms the transit network for use in connecting to the UDLR.

  • Connect the primary NSX ESG uplinks to the external networks

  • Connect the primary NSX ESG internal interface to the transit network.

  • Create the NSX UDLR to provide routing capabilities for tenant internal networks and connect the UDLR uplink to the transit network.

  • Create any tenant networks that are known up front and connect them to the UDLR.
