We have been reading Pega's documentation around SRS for connecting to externalized Elastic Search.    We are planning on having a shared Elastic Search per Environment and We are looking to create a separate namespace for the SRS instances (also one per environment) for all Pega Applications to connect.  We want to know Pega's recommendation on whether SRS Service be deployed on the same namespace as Elastic Search or having them separated (pros and cons that you can provide).   

Example: 

Namespace                 Namespace              Namespace

Pega app1 Dev            SRS Dev Shared     Elastic Search Dev Shared
Pega app 2 Dev           SRS Dev Shared     Elastic Search Dev Shared

VS

Pega app1 Dev                                             SRS and Elastic Search Dev Shared
Pega app2 Dev                                             SRS and Elastic Search Dev Shared

Thanks,

Steven
