You can run Windows Diego Cells in isolation segments, which are compartmentalized resource pools for Diego Cells.

Diego Cells in one isolation segment can share routing, computing, and logging resources with other Diego Cells in the same segment, and do not use resources from other isolation segments.

To run Windows Diego Cells in multiple isolation segments, you must create and install multiple VMware Tanzu Application Service for VMs [Windows] tiles and configure each to run in a different isolation segment.

To create multiple copies of the TAS for VMs [Windows] tile, see Replicating a tile.

To associate a TAS for VMs [Windows] tile with an isolation segment, so that its Diego Cells run in that segment, see Assigning a tile to an Isolation Segment.


To run a Windows Diego Cell in a particular isolation segment, the isolation segment must first already exist in the Cloud Controller database (CCDB) before the Windows Diego Cell can be assigned to it.

To create an isolation segment in the CCDB, see Creating an Isolation Segment in Managing Isolation Segments.

Replicating a tile

To make multiple copies of the TAS for VMs [Windows] tile that you can assign to different isolation segments, you must use the Replicator tool.

To use the Replicator tool:

  1. Download the Replicator tool from the VMware Tanzu Application Service for VMs [Windows] page on VMware Tanzu Network.

  2. Go to the directory where you downloaded the Replicator tool.

  3. Replicate the tile by running:

    replicator-windows -name "TILE-NAME" -path PATH-TO-ORIGINAL -output PATH-TO-COPY


    • TILE-NAME is a unique name for the new TAS for VMs [Windows] tile. The name must be ten or fewer characters in length and contain only alphanumeric characters, dashes, underscores, and spaces.
    • PATH-TO-ORIGINAL is the absolute path to the original .pivotal TAS for VMs [Windows] tile you downloaded from VMware Tanzu Network.
    • PATH-TO-COPY is the absolute path for the copy of the .pivotal TAS for VMs [Windows] tile that the Replicator tool produces.

    For example:

    C:\Users\admin\> replicator-windows -name "Shiny Tile" ^
    -path c:\downloads\TileOriginal.pivotal ^
    -output c:\temp\TileCopy.pivotal
  4. Install and configure the Windows isolation segment, using the new .pivotal file and, following the procedures in Installing and Configuring TAS for VMs [Windows], starting with the Import a Product step of Install the Tile.

Assigning a tile to an Isolation Segment

To assign a TAS for VMs [Windows] tile to an isolation segment:

  1. Select App Containers.

  2. Under Segment name, enter a name that is unique across your TAS for VMs [Windows] deployment. This is the placement tag for your Diego Cells.

  3. Click Save.
