Introduction

In today's business world, competition is fierce and relentless. As a result, maximizing uptime while reducing downtime and its expenses is a top priority. In particular, users now expect applications to deliver consistent performance, regardless of unexpected challenges. Payara Server offers a high availability (HA) architecture that is designed to keep your business operational at all times. This blog post explores the components and configurations needed to create a highly available Payara Server environment, ensuring your applications remain accessible and responsive.

Avast ye, Payara Community! We are ready to chart our course for new horizons in June, but before we do, let's take a moment to look at all the treasures our old salts developed to power up your Java and Jakarta EE applications. We've collected the best pearls and gems in our latest roundup - check them out now!

All aboard, Payara Community! It's time to hoist the sails and set course for new adventures in May. But before we do, let's take a look back at the treasures we uncovered in April. We've gathered our favorite catches from the depths to share with you, ready to power up your Jakarta EE applications and propel you towards success! Join us as we navigate through the highlights of the month in our latest roundup

Introduction

The asadmin Command Line Interface (CLI) is a mean of controlling Payara Server from the command line (or terminal, if you prefer). It allows you to start, stop or edit the server in a number of ways. While to some the administration console is the go-to for any administration that needs to be done, the CLI can be a potentially quicker and easier way of performing any administration tasks, particularly when dealing with headless servers, i.e. a server without a GUI.  

When dealing with complex distributed systems, decoupled, asynchronous communications may be more suited to support the exchange of information between different parts of a system, or even completely different systems. In effect, this decoupling makes it possible for different parts of a system to interact without being directly connected, enhancing scalability and fault tolerance. It is possible to set up such communications through a messaging platform like Apache Kafka and design highly scalable applications.

Our new eBook - available to download here - discusses how to use Apache Kafka for Jakarta EE Platforms that use Payara Server. 

Ahoy, Payara Community! Here's an overview of our fresh catch for March, where we've reeled in our favorite bits from the depths for you to enjoy and power up your Jakarta EE applications!

Greetings Payara Community! Enjoy our favourite bits we gathered in our monthly catch for January.

The Payara Platform is a comprehensive ecosystem designed to meet the diverse needs of today's enterprise Java developers like you, offering robust solutions for Jakarta EE applications. The Platform is split into two main products, namely Payara Server and Payara Micro.

Sealed classes are a powerful feature introduced in Java 15 that allows developers to control the inheritance hierarchy of a class. In this blog, we will explore the concept of sealed classes in the context of Jakarta EE, a set of specifications for building enterprise applications in Java.
