Both Payara Server and Payara Micro can cluster together and share data using Hazelcast. Out-of-the-box, there is no configuration needed, since Hazelcast uses multicast to discover and join other cluster members. However, when running in cloud environments like AWS, for example, there are a lot of things which can stop discovery being quite so straightforward. The key thing is that Multicast is not available, meaning another discovery strategy is needed; the most common generic alternative is to use TCP, but this assumes that you know at least the intended subnet that your cluster members will be in ahead of time.

In case you missed the news earlier this week - we are pleased to announce a new release of Payara Micro and Payara MicroProfile 171 to start the new year with a bang! With this new release, we have implemented substantial changes that are meant to improve the stability and usability of both 'regular' and MicroProfile version of Payara Micro. As is usual with our releases, keep special attention to our blog in the following weeks to read detailed articles on these changes and features to take full advantage of them!

For Payara support customers, LTS - Long Term Support - has been introduced for both Payara Micro and Payara MicroProfile so you can expect a full year of patch releases which only include fixes - great news for users who value stability over new features (find out more about the support services here)! 

All new changes and features introduced in this release are also included in Payara MicroProfile unless explicitly stated.

In our continuing series on alternatives for commercial Oracle GlassFish features , in this article we are looking at Hazelcast - a replacement for Oracle's Coherence ActiveCache.

Payara Micro is packed with most of the features and APIs that come with Payara Server Full Profile even though it doesn't entirely support whole Jakarta EE Full Profile. As an example, Payara Micro supports persistent EJB Timers, which are only required by the Jakarta EE Full Profile and not by the Web Profile. In Payara Micro, it's possible to use persistent EJB Timers, which are stored across your micro instances inside the distributed data grid as long as at least one instance in the data grid is up and running.

As part of the new features introduced with the release of Payara Server 162, you can now form a cluster of Payara Server instances using the concept of Hazelcast “Lite Nodes”. This can help you create more flexible cluster topologies.

Recently I attended as a speaker at my second jDays, a great conference in a great venue in Gothenburg. jDays is a fantastic conference as it is small enough to easily meet people and network and discuss tech, while at the same time big enough to run multiple tracks so there is always a session on that you’ll be interested in.
