The Payara Monthly Catch: January 2022

Photo of Priya Khaira-Hanks by Priya Khaira-Hanks

It's the first month of 2022 and we've already seen some fantastic news, articles, podcasts and videos related to Java, Jakarta EE, MicroProfile, cloud programming, DevOps and open source. We've collected some of our favourites in our monthly roundup. 

It's the time to evaluate your practices and look to the year ahead. So expect quite a few 2022 guides and roundups below: fromJava predictions in generalto some much neededsecurity auditing tipsin the wake of the Log4Shell vulnerability. 

There has been a lot of bold content this month, with experts not afraid to challenge commonly held views. For example, Ralph Soika queries if Spring Bootreally is state of the art anymore; Holly Cumminsquestions an indiscriminate approach to cloud native, and our own Rudy De Busscher asks:is Red Hat OpenShift really saving you hassle, or is the vendor lock-in too big a price to pay

This all fits with Payara's attitude of right problem = right solution. It seems the entireJava community is waking up to the fact that buzzwords and exciting tech simplify our view of the Java /Jakarta EE ecosystem, and really it's more about finding what is right for you specifically. If you haven't seen it yet, make sure to watchPayara's take on "Hype-Driven Development", explaining why technology likeKubernetes, reactive programming and Ahead-of-Time Compilation can be overrated and may actually not be right for smaller businesses. 

We've also had some birthdays to celebrate! The Eclipse Foundation- the open source organisation that stewards our core technologyJakarta EEand of which we are a member -turned 18 this month. Happy 21st birthday toIntelliJ IDEA, an IDE Payara is compatible with (we announced our updated plugin, now supporting Version 2021.3 and newer, this month too). Again in the theme of new not always equalling better, the benefits of working with a 26-year-old programming language is an ecosystem of strong, established supporting organisations and technologies: perfect for Enteprises that need stability and security most of all.
