The Payara Monthly Catch: April 2022

Every month, we collate the very best content for our specific enterprise Java – Java EE, Jakarta EE and MicroProfile – community. We also look further afield, and where it applies, include interesting blogs, videos and articles on subjects such as DevOps, cloud computing, microservices, software architecture and more. 

TL;DR: We know our audience and if we think you will find something very useful when developing enterprise Java applications – it makes the cut! 

This month, we are still gearing up for the Jakarta EE10 release. This is a major release, and our CEO Steve Millidge talked about why alongside Ivar and Tanja from the Eclipse Foundation in our boldly-named webinar, ‘Why Jakarta EE 10 is the biggest thing to happen to Java in 20 years.’ You can watch it now.

A particulary strong article we saw this month was Nicolas Frankel on chopping the monolith. Microservices vs. monolithic often becomes a polarized debate. However, Steve reiterated in the above webinar that it isn’t a case of ‘either/or’, and this is also what Nicolas argues. Instead, a hybrid model, mixing the architectural styles, is what many developers choose. We love these more measured approaches, that don’t fall victim to the ‘buzz’.

Next month is likely to be a busy one, with the release of Jakarta EE 10 and the FINAL Payara 5 Community release scheduled. Find out a little more about what this will mean for you if you are using it here, though we will be following up with more blogs and a webinar. 

Enjoy the calm before Jakarta EE 10 with a great range of ‘How-to’ and informative pieces below.
