Scaling Epic-Stack in a single region

Hi Kent, my name is Tim, I have a few questions regarding scaling the Epic Stack within a single region. With the assumption that we are having huge amount of users in one region, my question is would you recommend switching to other database technologies or would you have multiple SQLite replicas in the same region, with each of them being connected to remix apps in a 1-1 manner My second question is, assuming that we have the epic stack setup, what would you do if one remix server can't just keep up anymore with the load. Would you introduce caching or any types of application or additional threads to distribute and keep up with the work load Thank you Scaling Epic-Stack in a single region
