SOA: Businesses increasingly adopt SOA for greater Flexibility and Control

By Dick Weisinger

Services Oriented Architecture (SOA) is a software design methodology that modularizes software into discrete self-contained services.  Each service is designed to provide a tightly-defined function and is typically accessed over a network as a web service that can exchangesdata formatted in XML or JSON.  Applications are then built up by combining the component SOA services.  The SOA architecture is considered an IT best practice and it provides great flexibility for swapping in and out different services within an application and for sharing service capabilities between applications.

The benefits of SOA include control, agility and cost savings.  The software reusability that SOA provides allows businesses to more easily adopt to changing market conditions.

Sandra Rogers, analyst at IDC, said that “businesses need the ability  to adjust quickly to dynamic market conditions. Enterprises are now global and partner relationships are becoming increasingly complex. Entities within the value chain need to share processes—and the information that enables those processes—faster and more flexibly to maintain competitive advantage.  And they need to create a foundation that they can work with on an ongoing basis, rather than solving discrete needs one at a time.  Plus they need to address the continued pressure on IT organizations to reduce costs.”  SOA architecture is designed to help businesses do that.

The SOA market is on a rapid climb.  Between 2010 and 2012, the SOA market grew from $4.0 billion to $7.1 billion.  Wintergreen Research forecasts that SOA will grow to a $15.1 billion market by 2019.  Their estimate is that roughly 18,500 large companies worldwide are currently using SOA, and that there are another 14,800 smaller ’emerging’ companies with revenues between $300 million and $2 billion that are using SOA.
