>Startup are a none issue

Yes it is. Developing any short term job -- that runs multiple seconds and goes away -- like lambda or k8s jobs with Java is meaningless for exactly this reason. The startup time is longer than the run time.

A Minecraft server is not a short term job.

I guess it can be in a specific case: minigames servers (such as Hypixel), which are just a bunch of servers "connected" together. Players start into a "lobby" server, where they can choose a minigame, and are then sent to another server where they spend a few minutes.

The JVM can start up in less than 0.1 seconds. Depending on the amount of classes being loaded it is not an issue even for lambda and k8s jobs.

[vips7L]

The VM starts up plenty fast. The slow part is when people use reflective dependency injection containers that take seconds to scan the class path before before executing.

You clearly did not deploy enough classes on Lambda to have more than 10 seconds warmup on a trivial Java based Lambda function.

This is a Minecraft server, so it's going to be running 24/7.

I see you aren't familiar with modern state of Minecraft servers. Due to Minecraft being limited to a one core big servers actually aren't a single instance. They use proxy servers(such as BungeeCord and it's forks) which distributes load between several lobby servers and from there people join one of custom gamemodes(Skyblock, Bedwars, etc). This allows for tens of thousands of people to play simultaneously, but not in the single world, while SMP(Survival Multiplayer) servers can run couple of hundreds at most. These giant servers are heavily containerized and automatically scale under load, so spinning up and shutting down servers is a pretty normal thing. And there have been some attempts to make Minecraft to run a single world on multiple instances(MultiPaper and some private ones), so even for usual SMP server it can be a commonplace soon as player join and leave.

I encourage my competitors to keep thinking this.
