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.   

It's Nugget Friday again, and we're excited to bring you another valuable titbit to our beloved coders! In this instalment of our Friday Nugget series, we're diving into a common yet essential task for developers, especially when handling data read from a file, network or database: converting an InputStream to a String in Java. Knowing how to do this is crucial for efficiently managing IO and data processing tasks.

Innovation is at the core of some of the most exciting software applications currently available and in development. It's important to recognize these solutions, as the stories behind them can inspire developers as well demonstrate the real-world impact of a reliable and future-oriented application server in pushing boundaries in software development. In line with this commitment, we're delighted to shine a spotlight on Payara Community member, TechnoLynx, by interviewing its CEO and Founder, Balázs Keszthelyi. In this blog post, he discusses what the organization does, its applications and how it uses Payara to power key applications.

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.

'Java' can be considered an umbrella term encompassing different technologies rather than a single element or solution. This webinar with Simon Ritter from Azul  & Luqman Saeed from Payara - watch here - shed a light on what different Java aspects and components,  illustrating how software developers can leverage these technologies, including runtime options, to deliver highly effective applications.

The Payara Platform promises aggressive compatibility. Because we focus on providing an excellent application server, we do not seek to lock you in to a product suite or any particular tools. As you see in this blog, this is also true in the case of which implementation of the Jakarta Persistence API specification you choose to use. We explain why we run automatically with EclipseLink, but also why and how you may switch to Hibernate. 

Choose the tool that is right for your specific use case. 

Avanzando más nuestra serie de blogs de introducción, esta entrada mostrará como puedes escalar de forma dinámica tu cluster, y como Payara Server maneja la conmutación por fallas entre miembros del cluster.

See here for the original version in English language.

La conmutación por fallas es la habilidad de continuar proporcionando acceso a nuestro sitio web o aplicación en el caso de que un servidor falle. Es una parte importante de un servicio que goza de alta disponibilidad, cuyo objetivo es minimizar los tiempos de inactividad a lo largo de tu infraestructura de servicios.

Taking our introductory series onwards, this blog will look at how you set up a simple Payara Server cluster on Windows using the native remote control protocol, DCOM. We will set up two instances on Windows 10, controlled by a third Domain Administration Server (DAS) instance on Windows 7 via DCOM, and cluster them together using Hazelcast. Finally, we will deploy our trusty clusterjsp application to demonstrate how the data is being shared across our instances.

Further developing our introductory blog series, this post will look at how you can dynamically scale your cluster, and how Payara Server handles failover between cluster members.

Failover is the ability to continue to provide access to your website or application in the event of a server failing. It is an important part of high availability hosting, which aims to minimise downtime across your server infrastructure.

This article continues our introductory blog series on setting up a simple cluster with Payara Server, carrying straight on from our last blog where we set up load balancer on our cluster.

By clustering our Payara Servers together and balancing traffic between them with Apache Web Server we keep the benefits of having our application accessible from a single URL and gain the resilience and expansion prospects from having our application deployed across multiple instances.
