embeded hazelcast vs external hazelcast
Hi,
when we should consider to use external hazelcast instead of embeded hazelcast for pega cluster? is the Max number of nodes threshold above which we must move to external hazelcast?

You should consider preparing your application for exernalized hazelcast.
It will certainly be mandatory once. It's already more than highly recommended.
Embedded version was the default and it will indeed use some resources and hazelcast as such can have its own issues. Embedded or not, it's a component which can create some troubles or which can be troubled.

Hello,
There's not much limitation I think but this needs to be considered for your future version/upgrades.
It's a global strategy/decision not to handle/host anymore inside PEGA some external components which are not purely PEGA.
This also goes in direction for a clean node classification & easier set-up and horizontal scaling. Avoiding mixing fully different roles for some nodes.
You also need to consider maintenance & upgrades of hazelcast which, when externalised, can be done independently of your PEGA application/version.
Well, this is my POV & Understanding :-)

@Anthony_Gourtay Thanks for your reply.
So having hazelcast embedded, should not cause any performance issues or cache replication issues within nodes right?
