Dedicated index pool and bootstrap still needed?

Hi all

We are planning a new networker 18.2, 19.1 setup and i was asking myself if we sill need a dedicated pool for bootstrap and index now with DataDomain and cloudtier?

We have an old setup that run Networker 8.2.4 and we didn't dedicate an index pool or bootstrap with the pro's and con's that come with it.

Our setup will be 2 DD on 2 sites (1 prod and 1 dr) with replication and clourdtier for LTR

any inputs helps

Regards
