I have deployed Open edX on k8s with tutor and would like to increase the number of replicas from 1 to n on the following deployments:
I believe that the lms and cms keep session data and cache in memcached, and persistent data is stored in MySQL and mongoDB. This leads me to suspect that the pods in these deployments are stateless, and scaling them horizontally should be as easy as increasing the number of replicas. Are these assumptions correct?
I have read about Open edX architecture and watched appsembler’s talk but these sources do not provide information about the tutor distribution. I also haven’t found any information about scaling in the tutor docs.
