I have a kubernetes cluster running in AWS with RDS (postgres) i created a memcached namespace installed memcached with helm in there. pod is up and running. it has deployment and service yamls. also theres application running in kubernetes cluster. it is not simple application but business java application. Question is how this thing works? what in case if i have like 50 applications running (MULTI-TENANT so data must be isolated). i mean how all these apps should know to connect to memcached. data must be retrieved from memcached before the database. i cant figure this out. any help or tips appreciated.
