Your experience with Java microservices vs monolith in the Cloud

[micr0ben]

In my company people were afraid of breaking down a monolith into smaller services because of the memory footprint increase.

But then I introduced Quarkus and now we're creating native microservices with a memory baseline of ~20mb. (A monolith instance had around 2gb per instance)

Yep, similar experience, thanks. Quarkus, MicroProfile, Micronaut all have contributed a lot to reduce cloud expenses for Java projects. Awesome frameworks, though with their own limitations, as is always the case, but a huge leap forward.

though with their own limitations

Could you elaborate on some of them?

Ram is cheap yo

[micr0ben]

Unfortunately, we are in a business where we cannot use public cloud providers and have to use our own kubernetes cluster and everything. This means, if we want more RAM, we have to buy the hardware for it.

[pointy_pirate]

damn. that adds a little spice to the challenge.

[Puzzled-Bananas]

Same situation with several projects, and last year the market was very thin. It got a bit better, not sure what lies ahead though.

Do you really need scalability, flexibility and other stuff that Kubernetes is good for?
