What is SOA? SOA stands for “Service Oriented Architecture”. SOA is an architectural approach using technology to present business processes as reusable services. SOA is focused on the business and enables process transformation to new levels of integration, visualization, monitoring, and optimization.SOA is not a technology, it is a concept and a strategy for using technologies to build business automation solutions. SOA can be achieved through web services like BPEL. What is BPEL? BPEL stands for “Business Process Execution Language”. BPEL is a technology used to build programs in SOA architecture. Difference between SOA and BPEL SOA is an architecture and not a technology. BPEL is a technology to build SOA architectural programs. Advantages of SOA architecture and BPEL technology 9.

Being SOA an architectural concept rather than a technology it is concentrated on business rather than development or coding. 10. Using SOA architecture and BPEL technology you can integrate multiple legacy systems through reusable services/objects. 11. BPEL provides handshaking which means you can track what is happening to your input. If it is successfully processed or not. 12.
