Enterprise Integration for Beginners

First I want to tell you that this is not a 1 minute tutorial as the “Sams Teach Yourself” series. This is about deploying your next WSO2 server (first server you deploy after following this tutorial) in 1 minute . Enough talking and let me take you straight in to the task. The concepts and the configurations I am describing here can be used in any kind of scalable deployment with WSO2 products. Below is a diagram of a system which we normally see in an enterprise integration project. Here you can see there are 3 set of systems and a number of WSO2 servers in the entire deployment. The generic approach to this kind of deployment is to first do the end to end implementation within the development setup and then move these configurations in to QA and Production systems. When you are installing your QA or production environment, you need to make sure all the things that done within the development setup are there in the production setup in a seamless manner. You d...

Installing puppet on red hat linux based system This blog post will guide you through installing puppet as a master/agent configuration in a RedHat Linux based systems. This is nothing other than collecting the important information mentioned in the puppetlabs web site. What I have done is collecting pieces of information which is scettered through the puppet web site with adding my own experiences which I have gathered during setting up on my environment. 1. Choose a Package Source Puppet Labs provides an official package repo at yum.puppetlabs.com. It contains up-to-date packages, and can install Puppet and its prerequisites without requiring any other external repositories. This information applies to RHEL itself, as well as any distributions that maintain binary compatibility with it, including but not limited to CentOS, Scientific Linux, Oracle Linux, and Ascendos. Enabling this repository will let you install Puppet without requiring any other external...

What is Puppet? Puppet is IT automation software that helps system administrators manage infrastructure throughout its lifecycle, from provisioning and configuration to orchestration and reporting. Using Puppet, you can easily automate repetitive tasks, quickly deploy critical applications, and proactively manage change, scaling from 10s of servers to 1000s, on-premise or in the cloud. How the puppet works? It works like this..Puppet agent is a daemon that runs on all the client servers(the servers where you require some configuration, or the servers which are going to be managed using puppet.) All the clients which are to be managed will have puppet agent installed on them, and are called nodes in puppet. Puppet Master: This machine contains all the configuration for different hosts. Puppet master will run as a daemon on this master server. Puppet Agent: This is the daemon that will run on all the servers, which are to be managed using p...
