Payara Server Rolling Upgrades

Any project, large or small, would ultimately like to follow industry best practices, such as continuous deployment.  In order to support this, applications must be deployed early and often.  This, in turn, triggers downtime and the users get affected by it because they could be logged out of the website, or worse, their work gets lost because the application's intermediate state is not saved - never mind the actual downtime during the application deployment process.

 

Rolling upgrades solve this problem in an efficient way!

 

Persistent EJB Timers in Payara Micro

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.

Flexible Clustering with Payara Server

Application server clustering provides a means to make application infrastructure more robust and perform better. However, it is often very inflexible and even a small change in the cluster topology can involve serious maintenance costs. Payara Server supports a new way of clustering based on Hazelcast, which brings much more flexibility, decreases maintenance costs and adds the benefit of JCache support out of the box.

 

Java EE Microservices Platforms & High Performance Java EE with JCache– jDays 2016

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.
