Can I use the same Redis instance for both backplane and distributedcache?

[gumbarros]

I'm on a on-premise environment where is more hard to configure things.

I have a WebSite and a WebApi and I want to sync the HybridCache of both, the backplane is the best option right? But should I use the same Redis instance for backplane and distributed cache?

Hi @gumbarros , yes in general the idea is to use the very same Redis instance for both the distributed cache and the backplane.
In Redis the distributed cache part uses the key-value features, while the backplane part uses the pub/sub features.

This is true for:

• multiple instances of the same app
• multiple apps that need to share the same data (eg: back office and front office apps), even with multiple instances of each app

On top of that, you can use the same Redis instace even for totally different "logical caches", even for totally different apps, and to do that you need to use Named Caches with a carefully selected CacheKeyPrefix to avoid cache key collisions and similar problems.

Hope this helps.
