The problems boils down to the fact that these years maybe BPEL has been marketed for something which isn't: that is a Business Process Management framework.īPEL is made up for service orchestration, that is publishing new services as a function of other services. In my opinion BPEL and BPM are quite different things so they cannot even be compared. The Service-oriented movement to agility and loose coupling demands a shift from traditional, waterfall styles of development (design-build-test-deploy-manage) to iterative approaches to continuous Service modelingĤ4.What do you think about BPEL and BPM ? How do they compare? Successful SOA adoption requires a cultural shift in the way IT is done. The critical flaw in thinking is confusing the technology that sits beneath the Services level of abstraction and the mechanism by which Services are accessed with the architectural approach that aims to decouple the implementation from the consumption and focus on sustainable architecture that allows for continuous change. Put it this way, SOA is nothing more than Web Services and standardized middleware. In my opinion one of the biggest obstacle in the movement towards SOA adoption is the organization’s own IT department.Too many people in the IT organization conceive SOA as a technology concept only, and as such think of SOA as just a set of technologies and infrastructure for exposing, securing, running, and managing Services. It uses annotations and other JDK 5.0 features.Ĥ3.How would you convince my IT department to adopt SOA? This option assumesthat the container has exclusive access to the persistentstore and therefore it doesn’t need to synchronizethe in-memory bean state from the persistent store at the beginning of each transaction. You could activate the "Commit Option A" that is the container caches entity bean state between transactions.
