Enterprise Integration for Beginners

Distributed systems has come a long way from where it started and have a long way to go. With more and more people connected through telecommunication technology over the largest distributed system on the planet which is the internet, the demand for an efficient distributed architecture is ever so important today. This is not a tutorial on distributed systems though. Rather some thoughts on building a futuristic distributed system which addresses the challenges of the modern needs keeping the focus at the messaging styles. In a distributed system, messaging plays a pivotal role. Data flows from one system to another through messages. Different protocols and formats are used to share data within a distributed system as messages or events. Another key aspect of messaging is the nature of communication The below post explains different messaging styles and how those can be used to build a future proof distributed system for the enterprise. https://medium.com/@chanakaudaya/a-futuris...

Distributed systems (to be exact, distributed computer systems) has come a long way from where it was started. At the very beginning, one computer could only do one particular task at a time. If we need multiple tasks to be done in parallel, we need to have multiple computers running in parallel. But running them parallel was not enough for building a truly distributed system since it requires a mechanism to communicate between different computers (or programs running on these computers). This requirement of exchanging (sharing) data across multiple computers triggered the idea of the message-oriented communication where two computers share data across using a message which wraps the data. There were few other mechanisms like file sharing, database sharing also came into the picture.

Well I guess you have come to this page with the intention of learning something about Apache Axis2. If you search for google the word "Apache Axis2", you may get millions of pages. But most of them have some pre-requisites before teaching you about Apache Axis2. My intention with this post is to share my experience about learning Apache Axis2 from level zero. If you have used a computer and know how it works, that would be enough. Since you have used computers, you might know what it does. It does some computing task for you. All the processing, memory, power, data all the components are within a single place and that is what you called your personal computer. That is enough for processing your word document, print your photograph and many more personal things. Let's think about something bigger than your computing need. Think about a bank doing day to day transactions on their hundreds of branches and each one of them are connected with each other. In this scenario,...
