Using SubVSs has many advantages, such as:

  • SubVSs are linked to, and use the IP address of, the ‘parent’ Virtual Service.

  • Using SubVSs reduces the number of IP addresses required by applications such as Lync or Exchange

  • SubVSs are always transparent to the main Virtual Service

  • SubVSs may have different settings (such as content rules) to the parent Virtual Service and to each other

  • Using a SubVS provides the ability to have content switching and persistency on the same Virtual Service

  • Using a SubVS gives the ability to perform multiple health checks on the same Virtual Service
