Hello,

the guys in My Support Portal couldn’t help me with my question

In the future, pega will no longer provide Elastic Search via its Docker Repo. Is it therefore possible to replace this Elastic Search with Pega SRS and Elastic Search for an existing system?

Furthermore, I noticed that in the values.yaml of the Pega Backingservice an Eleastic Search will be configured by default.  
Can I use this or will this option disappear in the next releases?

Should I use the Pega SRS or should I install an Elastic Search from e.g. bitnahmi and simply configure its address in the Pega Helmcharts at Pega Search, what is the best way?

For information, in the cloud we use there are no managed services available for Elastic Search, Kafka or Cassandra.

This means that they have to be installed separately in the cluster.

Thank you

Regards Julian

If these do not provide the details then perhaps our SME @szadp (who ran a very popular [Ask the Expert](https://support.pega.com/discussion/ask-expert-pega-search-pawel-szadkowski)) can help you further.
