Highly doubt that. It really depend on the scale of your 
operations.

Interestingly while Docker may seem all the rage in startups I 
find its use limited to test environments in the real world.

Also Java fat jars were super easy to deploy ages before docker. 
They are also a great deal smaller.

Honestly APIs these days can be written in anything that is able 
to put together a few HTTP responses. Unless you are doing 
serious work like:
- DBs
- Search engines
- ML pipelines
- Real-time event processing systems
....

Any semimodern language/technology with a several hosts can 
manage to saturate 1Gbit link. Some take a certain amount of 
tuning others work out of the box. If you go for 40gbit/s it may 
be important to choose the right technology otherwise it’s all a 
matter of taste.
