SOA

SOA (Service Oriented Architecture) become a buzzword in technology arena. I started to hear this from two to 3 years back but don’t know what exactly even now. I mean the implementation point of view. SOA is mostly related to integrating various systems may be working in different platforms,technology etc. SOA gives a common language or plug-in type architecture to communicate with different system. The ROI of SOA is pretty impressive. Some figures shows like if it requires $40000-$50000 to integrate system without SOA in place it requires just 3000-5000 $ to build the same if the SOA is already in place. SOA always gives long term benefits for long term big projects. You should have a long term vision to reap the benefits of SOA. Because of this it’s very difficult to convince the benefit of SOA and also the initial investment will be more compared to the projects without SOA in place. One other challenge that companies are facing is that the shortage of skilled professionals. There may be chance of performance issue also as it involves various systems and chances of network issues /performance issues are more. Another challenge is ofcourse managing interrelated systems. Challenges to ensure the security for the complete/part systems involved is also there.
