With the risk of asking an obvious question:
If I were to set up two pods running a spring boot application with shared memory (https://access.redhat.com/documentation/en-us/openshift_container_platform/3.10/html/developer_guide/dev-guide-shared-memory) and use Ehcache for caching requests to a database. Would I need to set up a distributed cache with e.g. Terracotta/Move to another caching manager such as Redis? Or would the cache also be shared between these two pods with the shared memory?
How does the shared memory affect the cache of the two pods?
