Fast Spring Boot AWS Lambdas with GraalVM

In my previous blog post I documented how to take a Java Spring Boot application and convert it into a serverless function, which can be run in the likes of AWS Lambda. Anyone who’s done this before knows that cold starts are a big downside – Java and Spring Boot are not known for their speedy startup times, and a typical full fat Spring Boot converted lambda can take anything from 10 to 90 seconds depending on how much memory and cpu you allocate it. This may lead you over-provision them to compensate for the cold starts, but that’s a...

Each meeting room had a touch screen setup outside of it, and from it you could see who’d booked the room, and also use it to book the room out if it was available. It had the right idea, but from talking to people I learnt that it wasn’t the most user-friendly, and that it had cost a pretty penny too! I’d been looking for an excuse to...
