### Problem Description

Currently, the Demo version is run with an in-cluster Redis cache. This doesn't reflect the real-world hosting scenario very well.

_Caveat:_ This might be very expensive, as managed Redis is costly. Please, still do this using the smallest instance possible to demonstrate MPM has the functionality. We might later roll this back to in-cluster to save costs.

### Proposed Solution

Please create a (small) dedicated Redis cache to be used in the Demo environment.

### Alternatives Considered
