I have a bunch of platforms that’re just jarfile monoliths (with external db/redis) that we deploy by provisioning the latest Amazon Linux onto EC2, then running a Ansible to configure and add our local dependencies and the jarfile, then run the start script. While our Ansible step runs quickly enough, this is a nice way to not worry too much about managing our own AMIs. (Two things really help here, we have Windows/macOS/Linux devs all developing and running the code locally so they’re pretty good at not accidentally becoming dependant on stuff outside the JVM, and the healthcheck endpoint the load balancers use is very comprehensive and over the years has been updated to include every non-detected failure or performance degradation.)
