They're VM's but much more efficient and start faster. There's a clever but shockingly naive build system involved. That's pretty much it.
Going beyond this you get orchestration - which you can certainly do with VM's but it's slow; and various hangovers from SOA rebadged and called microservices.
But they're really, really efficient compared to VM's.
