SOA for dummies - Basics and best practices

Posted by Blogger Name. Category:

SOA is a interesting feature which is getting evolved in current trend and below practices will give a clear basics of SOA to dummies too.


How SOA Evolved

Technology advancements have primarily driven software architecture over the last three decades. It started with the use of applications that were built on Mainframe (monolithic applications). These changed into applications, which provided power to end-user desktops through the introduction of client-server architectures (such as, 2 and 3 tier). To satisfy the need for distributed processing, middleware components were introduced to harness the power of various heterogeneous applications distributed across the enterprise (composite systems with middleware). However, along with these developments, it was also important to address the problem of managing and evolving change. Applications designed with SOA principles were intended to address reuse and maintainability for aligning applications with changing business needs, rather than building applications influenced by new technology advances.

An SOA can help your organization…
  • Enhance business agility.
  • Synchronize IT with business.
  • Break the barriers between business units and business partners.
  • Lower the expense of maintaining IT systems.
  • Focus resources on innovation rather than maintenance.
  • Speed up delivery of web services to meet business demands.
  • Provide support for IT process automation.
  • Protect IT investments by building on existing infrastructure.
        To be successful, your organization must become increasingly flexible. That means your underlying IT infrastructure must keep pace with today’s quickly changing business dynamics. To achieve that agility, companies adopt Service-oriented Architecture (SOA) so its basics and practices need to be know to us.

         SOA supports the delivery of IT as a service. It permits your business processes to drive the definition, creation, and execution of services that can be shared and reused across your enterprise. SOA changes the way you think about the traditional IT architecture. It produces an end to monolithic, rigid, application architectures and the high maintenance costs associated with them.
