Major Migrations Made Easy by Tim Te Beek @ Spring I/O 2022

I'll write a more comprehensive review of Spring I/O 2022 in Barcelona soon. Until then, I'll post recordings of some of the talks I've found most intriguing during that conference. One of those talks was given by software engineer Tim te Beek on OpenRewrite - a tool for complex source code refactoring (e.g., framework migrations, vulnerability patches, and API migrations): Mostly focused on Java for the time being, OpenRewrite is a tremendously useful tool when it comes to refactoring the source code of ...

In other - only slightly more technical - terms, HTTP status codes can be categorised as: 1**: Informational 2** Successful 3**: Redirects 4**: Client errors 5**: Server error

New Stratospheric Blog Post on Faster Amazon ECS Container Deployments

This week, we published a new Stratospheric blog post on how we achieved faster Amazon ECS Container deployments.

Stratospheric Online Course: Early-Bird Offer

Earlier his week, we finally released the first iteration of the Stratospheric Online Course - a companion course to our ebook "Stratospheric - From Zero to Production with Spring Boot and AWS"!
