Enterprise architecture (EA) ensures business-IT alignment. Service-Oriented Architecture (SOA) bridges the gap between business and IT through well defined, business aligned services....
The objectives of EA and SOA are quite similar. However, while EA is a framework that covers all dimensions of enterprise IT architecture, SOA provides an architectural strategy that uses the concept of a 'service' as the underpinning business-IT alignment entity.

Enterprises are gravitating towards service-oriented architecture (SOA) to re-design their IT for the future. As with all other technologies, the adoption of SOA involves risks. These risks often manifest themselves during an SOA solution implementation and...
arise primarily due to insufficient detailing in the design of the SOA. This paper identifies some of the risks across different viewpoints of an overall SOA-based enterprise architecture. Awareness of these risks can help designers and architects adopt appropriate measures to continuously evaluate and mitigate them.
More and more companies are adopting SOA on a large scale. However, companies are also realizing that there are impediments to successful SOA adoption and growth. ...

Information technology systems used to last for a long time. Organization re-structuring was uncommon, as business did not demand it. But with ever-shrinking business cycles, IT must quickly adapt to changing business needs. Present-day IT systems must be built to change...
and organizational structure and culture must reflect this change for efficiency. The modern-day enterprise demands its resources - technology, people and processes - should be plug-and-play ready to help it to become an agile enterprise.
