> Minimum RAM for a sever doing something normal over tcp is measured in gigabytes. Some of my Java services run with around 256-512 MB of RAM per instance, in Spring Boot containers (though Quarkus and Dropwizard can be even more conservative outside of enterprise bloat situations). That said, I'm inclined to agree in general, as I've seen monolithic Spring applications that refuse to run with anything less than 2-4 GB of RAM given to them. Perhaps even worse yet, there's no way for you to properly cap the resource usage within containers so you'd end up with more aggressive GC inside of containers but without OOM issues, when they're given a memory limit. -Xmx regularly gets exceeded because that's only a part of the equation and the creators of JVM didn't really think of a case where you should be able to give the whole thing a number of MB/GB it's allowed to use, which would never be exceeded, whatever it takes. > My other gripe os that "write once run anyway" is no longer close to true, since Oracle. Mac, Linux x64 and Windows 64 are your only sane options. Agreed, then again with most "business" software running in x86 OCI containers seems like the only sane option. Though I guess it depends on the environment that people have grown accustomed to and how they've been burnt in the past (e.g. I'd never want to use package managers or worse yet, extract random tar/zip archives for "business" software, never install Tomcat on the system directly etc., only use containers that are 1:1 the same in all environments where they're run). Of course, web dev is just a part of the greater picture, so there's lots of nuance there as well. Personally, SIM cards running Java seems like insanity to me, though: https://en.wikipedia.org/wiki/Java_Card https://en.wikipedia.org/wiki/Java_Card Then again, I'd say the same about Python implementations that are geared towards embedded setups, personally even Go seems like a better fit if someone didn't want to use C/C++/Rust, though platform support would still be a relevant question.
