  -An admin creates an isolation segment by sending a `curl` command to the CAPI with a name to identify it. Isolation segment names must be unique across the entire system and not case-sensitive. Only admins can create isolation segments.

   The following example uses a CAPI endpoint and authorization token to create an isolation segment named `my_segment`:

  This topic describes how Cloud Foundry (CF) operators can isolate deployment workloads to dedicated resource pools called _isolation segments_.
  
  The Cloud Controller database (CCDB) represents isolation segments with a name and a GUID. When an admin creates a new isolation segment, the CCDB outputs a GUID for the new isolation segment object.
  
  To manage the isolation segment, a user can send `curl` requests to the Cloud Controller API (CAPI) endpoint with the GUID of the isolation segment and an authorization token. <%= vars.api_endpoint_book %>
  
  Basic operations on isolation segments include:
  
  * Create a new isolation segment
  * Retrieve an isolation segment object
  * List isolation segments
  * List orgs or spaces in an isolation segment
  * Update an isolation segment
  * Delete an isolation segment
  * Add orgs or spaces to isolation segments
  * Remove orgs or spaces from isolation segments

  The `curl` requests listed in the sections below make changes to isolation segment objects in the CCDB. Only admins can make these changes.
