The Payara Monthly Catch: August 2022

August is typically a quiet month, and whilst this is the case in terms of industry announcements, there have been incredible learning resources and general Java articles created. Here, we have rounded up some of the best of them, covering DevOps, cloud computing, Java, Jakarta EE, MicroProfile and open source.

We loved seeing Java getting some much needed love in two pieces of content that went viral: 'Don’t call it a comeback: Why Java is still champ' andthisReddit post. As theEclipse Foundation Executive DirectorMike Milinkovich put it, "Java has been around now for 25 years and I believe that it’s going to be around for another 25 years. I think it’s undergoing a renaissance, both from a technology perspective, but just as importantly from an ecosystem perspective." We are proud to be one of the open source vendors making use of freely available Java technology to innovate and build that ecosystem! 

Watch out for us in September. We'll be atJConfin Chicago, where one of our experts Fabio will be delivering his popular talk on integration testing. And we have a very exciting webinar coming up in partnership withAzul, where we will take onGraalVMand AOT Compilation - suggesting that new isn't always better, and there are reasons you should stick with JIT. Sign uphere.

In the meantime, we hope you enjoy the top content we have collated for you - get stuck in!
