Continuing our introductory blog series, this blog will demonstrate how to set up a simple Hazelcast cluster of two instances.
In contrast to a development environment, where a single server is enough to act as a "proof of concept", in production it is usually necessary to look at reliably hosting your application across multiple redundant hosts to guarantee a reliable service and allow for future scaling. With Payara Server, it is possible to easily create and add instances to clusters using Hazelcast, making configuration of a distributed application a breeze.
Continuando con nuestra serie de introducción, este blog va a demostrar como configurar un cluster sencillo de dos instancias mediante Hazelcast.
When developing an application on Payara Server, it is very common to deploy directly to a local Domain Admin Server (DAS) instance, since this is the easiest and most straightforward way to test some code quickly from an IDE. When taking an application further towards production, however, it is highly likely that a domain with several standalone or clustered instances will be used across remote hosts. In this case, it will be very hard to ignore an aspect of Payara Server that may not have been obvious before this point - the concept of nodes.
This blog post will cover both what a node is and the types of nodes available with Payara Server.
Cuando se desarrolla una aplicación en Payara Server, es muy común desplegar directamente en la instancia local del Servidor de Administrador de Dominios (DAS), ya que esta es la forma más sencilla y directa para probar rápidamente las aplicaciones desplegadas en su desarrollo. Al llevar una aplicación a producción, sin embargo, es muy probable que se utilice un dominio con varias instancias independientes o en cluster que residen en múltiples servidores remotos. En este caso, sería muy difícil ignorar un aspecto de Payara Server que puede no haber sido obvio hasta ahora - el concepto de nodos.
Kick-starting yet another year, we are pleased to announce our largest release yet - Payara Server 184.108.40.206. Building on a year's worth of updates and improvements, in this release, you can find 18 brand new features and over 60 new fixes and enhancements for Payara Server & Payara Micro! Given the size of the additions, look out for detailed blogs in the near future. For now, check out below for a summary of the changes in 171 release, and have a look at the full release notes.
In the first blog of this series, we configured our Apache Web Server. Our next step will be to set up request forwarding to send traffic to Payara Server. If you need guidance on installing Payara Server on Ubuntu, we already have a blog post covering the installation of a JDK and Payara Server which we would recommend you read before continuing with this blog.
In this blog series, we will aim to give an overview of the basics of using Payara Server in a production scenario using Apache Web Server (sometimes called httpd) and Ubuntu 16.04. Many of the concepts described in these blogs do not rely on the tools we are using here and can be applied to other scenarios.
