We are operating a paid online game and 10 folded our traffic within 3 days. That makes us extremely happy, but also quite stressed out because our servers are getting to their limits.
We need short term help by someone who has extensive experience tuning a Java, spring boot, Hibernate application running on an ec2 Host connected to an amazon managed Postgres instance.
your payment will be royally! we intend to throw dollars at the problem until it goes away.
The impression that I get from HN comment threads is that developer time is expensive and so "the right way" to handle problems like this is to simply spin up more and more EC2 instances until the problem eventually goes away.
