Who suits for SOA?

The IT infrastructure which includes various business critical systems of an enterprise are built over a long period of time.They cannot always be made with latest technologies as their is already investment being made in earlier systems.The organizations which breathe change like oxygen have to think new ways in order to integrate all its existing systems,new or legacy, in order to orchestrate its business process with its partners,suppliers and customers.The IT strategies of organizations change with mergers and acquisitions and leads to more vendor or application specific systems, sometimes repeat of an application by different vendor, in such a scenario whole IT landscape of an organization becomes quite complex.




SOA has opened new vistas to re-orient business on disintegrating business processes into services based over business components in such a way that existing business solutions and previously non communicating systems can also fit into the big picture.In a way it has given organizations a leverage to build new possibilities in a cost effective manner.The cost is a major driving factor upon which enterprises are banking their hopes on SOA.

The business houses want agile systems but without paying more to IT organizations and this has led IT organization has challenge to provide cost effective solutions through integrating legacy systems with new agile systems having new business capabilities.The only way this can be achieved through transformations in approaches for business and IT organizations together.

Asynchronous Vs. Synchronous Communications

Synchronous (One thread):   1 thread -> |<---A---->||<----B---------->||<------C----->| Synchronous (multi-threaded):   thread A -> |<---A---->| \ thread B ------------> ->|<----B---------->| \ thread C ----------------------------------> ->|<------C----->|

WebSphere MQ Interview Questions

What is MQ and what does it do? Ans. MQ stands for MESSAGE QUEUEING. WebSphere MQ allows application programs to use message queuing to participate in message-driven processing. Application programs can communicate across different platforms by using the appropriate message queuing software products. What is Message driven process? Ans . When messages arrive on a queue, they can automatically start an application using triggering. If necessary, the applications can be stopped when the message (or messages) have been processed. What are advantages of the MQ? Ans. 1. Integration. 2. Asynchrony 3. Assured Delivery 4. Scalability. How does it support the Integration? Ans. Because the MQ is independent of the Operating System you use i.e. it may be Windows, Solaris,AIX.It is independent of the protocol (i.e. TCP/IP, LU6.2, SNA, NetBIOS, UDP).It is not required that both the sender and receiver should be running on the same platform What is Asynchrony? Ans. With messag

Advantages & Disadvantages of Synchronous / Asynchronous Communications?

  Asynchronous Communication Advantages: Requests need not be targeted to specific server. Service need not be available when request is made. No blocking, so resources could be freed.  Could use connectionless protocol Disadvantages: Response times are unpredictable. Error handling usually more complex.  Usually requires connection-oriented protocol.  Harder to design apps Synchronous Communication Advantages: Easy to program Outcome is known immediately  Error recovery easier (usually)  Better real-time response (usually) Disadvantages: Service must be up and ready. Requestor blocks, held resources are “tied up”.  Usually requires connection-oriented protocol
