    Curious about the tests you made with java and go. Did you test classic JVM or the new native builds?

    We are currently using mainly java with some node sprinkled in there, but I try to move some thinks we have from K8 pods into lambdas as it doesn’t make sense having it running 24/7. One of my coworkers often looked for a reason /place to introduce go. So might be helpful info for him haha.

      I don’t recall which Java environment was used; I’m not a Java developer so some of those technical details went in one ear and right out the other. They did implement snapstart for Java lambdas and that made the warm start time similar to Go. But the runtime performance isn’t even close after they put a bunch of effort into trying to optimize it.

      I truly can’t recommend anything other than Go for lambdas. It’s better by every metric and it’s a lot easier to manage your infrastructure (just a single binary file with no file or environmental dependencies; it doesn’t get any more straightforward than that.) I’d definitely recommend doing a PoC to compare performance for your specific workload in Java vs. Go. As long as you have devs capable of writing Go, it’s a real winner. If you don’t, I’d still go with nodejs lambdas over Java; Java still seems to require a lot of tweaking to get its performance comparable. It’s a 30 year old swiss army knife, and it shows.

        Thanks for your answer.

        There is a lot of improvementsn happening in the Java space , so that might change over the next years.

        It’s better by every metric and it’s a lot easier to manage your infrastructure (just a single binary file with no file or environmental dependencies; it doesn’t get any more straightforward than that.)

        With these new native builds you also get a single binary file as far as I know ( I’m still kinda new to Java) and much better startup times. So today Java might perform a little better in this comparison.

        But I take it as a good chance for getting a chance to introduce go as a language.
