Difference between ASCS and CI

[Former Member]

Hi Experts,

I am a bit confused with the difference between the terminologies ASCS and CI. With the introduction of ASCS the Message and Enqueue services are separated from CI then why does CI terminology still exists in the installation guide or for that reason why do we still have to install CI in HA set up?

What services will be there in CI with the existence of ASCS? Will the CI still hold Message server and Enqueue server and will be a replica of ASCS?

The simplest HA setup what I understand is this-

Node A- ASCS + CI + DB (With DB and ASCS as SPOFs and clustered)

Node B - DI

So with this when Node A fails ASCS and DB gets moved to Node B and DI on Node B takes the place of CI. But my confusion here is if DI is taking the place of CI then CI and and DI becomes same in the whole architecture. Is it so?
