Robust and efficient application servers are essential for companies relying on software applications, whether these support e-commerce platforms, financial services portals or internal operations.  To help ensure smooth operations, deliver seamless services to users and generate revenue, it’s important that the runtime in place can offer maximum uptime to reduce cost while optimizing performance, profitability and user satisfaction. 

In this blog post, we share insights from industry players on the impact of unexpected application server issues and downtime as well as how to reduce them.   

Start-ups are hotbeds of innovation, where speed, agility and resourcefulness are key to success. But in the world of enterprise Java applications, managing complex cloud deployment infrastructure can quickly become a bottleneck and take up considerable time from your developers. To address these issues and streamline cloud deployments, we created Payara Cloud.

Deploying applications on Payara Cloud offers numerous advantages, including ease of use and scalability. However, like any platform, you might encounter some common issues. The good news is that these problems are typically easy to resolve. Below, we’ll explore common issues, compiled based on the expertise of our service team. For detailed steps and additional support, refer to our comprehensive troubleshooting guide.

Development productivity is crucial in Enterprise Java and Jakarta EE application development, supporting the delivery of high-quality software solutions quickly and efficiently. As a result, it is necessary to focus on streamlining development processes, optimizing resource utilization and empowering developers to work more effectively. Payara Micro Maven Plugin, Version 1, introduces a powerful tool – Dev Mode – designed to supercharge your development experience with Payara Micro. 

In our latest User Guide - available to download here - we look at this plugin, exploring its features, configurations and usage to help developers unlock stratospheric levels of productivity.

We are launching a new video series: Quick Fire Java with Payara! The first episode sees Payara Product Manager, Rudy De Busscher, discuss "Hype-Driven Development"; software investments based on "buzz" around a trend or product, rather than whether it actually works for your specific use case. 

Payara Microでは、Webアプリケーションを自己完結型で簡単に実行することができます。2016年5月のPayara Serverリリースからは、WARファイルの内容とPayara Microを構成するクラスやリソースを束ねる “Uber JAR” を作成する簡単な方法があります。

この “Uber” Jarは、Dockerコンテナ内でアプリケーションを実行するための最良の方法ではないことに注意してください。アプリケーションに小さなコード変更を加えるたびに、バイナリ全体のアップデートが必要になるためです。より良い方法は、Payara Microインスタンスを起動して、インストールが必要なアプリケーションを指定することです。詳細については Payara Micro Docker Image documentation をご覧ください。

At Payara Services, we have long been advocates of the benefits of using DevOps practices not only in the development of our products (like Payara Server & Payara Micro), but also in the core of our expert advice to our user base with our blog containing arguments for using DevOps practices, details of DevOps tools and new developments that benefit it.

This is an updated blog of the original which was published in May 2016

Payara Server provides the Health Check Service for automatic self-monitoring in order to detect future problems as soon as possible. When enabled, the Health Check Service periodically checks some low level metrics. Whenever it detects that a threshold is not met, it triggers alert notifications that allow to detect undesired behavior and predict possible failures. All of these automatic checks are very lightweight and run with a negligible impact on performance.

Back in 2016, we wrote about the importance of automation in taking applications from development to production with Payara Server. Since then, there have been a lot of changes both in Payara Server and Payara Micro and the wider tech landscape.

As a Java EE developer, I sometimes envy how fast it’s possible to see the result of a code change in a running application with interpreted languages like PHP or JavaScript. With Java, it’s always necessary to rebuild the source code in bytecode, which can be then safely updated only by restarting the whole application. And all developers know that restoring the desired state of the application after a fresh restart takes time and is tedious.
