Last time, I attended a meetup about using Java in serverless architecture! The session was led by Kamil, who has over 20 years in IT and has spent the last 3 years leading the migration of big monolithic systems to microservices on AWS. His experience with large-scale projects was really inspiring.
During the meetup, we saw a practical guide for AWS Lambda with Java. Kamil showed step by step how to create a simple “Hello World”, pack it into a JAR file, create a Lambda in AWS, attach the JAR, make a handler, and set up a trigger using AWS API Gateway. We tested the Lambda with REST calls (“arrows” from API Gateway) – and everything worked perfectly the first time!
There was also discussion about whether Java is the best choice for Lambda, costs, and some interesting serverless tips.
No pizza this time 🍕, but the meetup was very useful and showed how to build serverless functions in Java in a simple and practical way.
If you want to start learning AWS Lambda with Java, I definitely recommend these meetups!
