The Payara Monthly Catch: July 2021

Welcome to our July Payara Monthly Catch – a collection of articles, videos & podcasts around Java, Jakarta EE, MicroProfile, open source and cloud computing. This month, the list mixes up quirky content you may not have seen – weird programming facts, tips on using the Snowflake Database – to insight from some of the most esteemed experts in the industry. Payara Platform has also been appearing all over the web, as influencers and our community use it in demos and discuss our products in conferences. Find out where Payara can be found across external blogs, conferences and media outlets in our ‘Featuring Payara and Payarans’ section.

On the internal news side, we announced that Payara Server Community 6.2021.1.Alpha1 is now a Certified Jakarta EE 9.1 9.1 (Full Profile) Compatible Product! Even though we aren’t encouraging users to run Payara Server 6 in production yet – you can achieve the same result, migrating to Java SE 11, in Payara Server 5 – this is important news in the journey of Payara Platform products alongside Jakarta EE.

We also published a full summary of what we got up to for our annual team-bonding company event, Payara Week – from chocolate Payara fishes to cocktail making challenges, open source business model learning to daily workshops.
