Why You Don't Need to Worry About Scaling Your Spring Web App
When writing a new Spring web app, teams often have some nagging scaling doubts: – How many users can my app simultaneously handle? – How fast will my @RestControllers dash out those JSON responses? – How much memory, CPU, or I/O does my application need? – How much money do I need to spend on hosting? Surprisingly, there's very little advice out there on how to sensibly approach these questions in a practical way—apart from simply autoscaling random Kubernetes pods into oblivion. In this #almostnoslides session, Marco Behler uses an IDE, a pen tablet, and a few libraries to give a deep, practical understanding of the following: – Throughput and latency: How to (reliably) find out how many users your Spring app can handle – CPU/memory/IO: How much (or how little) your app actually needs – Hosting: What server your app needs By the end of this talk, you’ll have learned solid load-testing processes and skills that make sure you never have to worry about scaling your Spring web apps again.
