Service-oriented architecture (SOA): High-impact Strategies – What You Need to Know: Definitions, Adoptions, Impact, Benefits, Maturity, Vendors.
SOA is an architectural style whose goal is to achieve loose coupling among interacting software agents. However, it has a certain number of disadvantages. For example, SOA does not involve synchronized thinking. The SOA process demands illogical steps that may not be relevant to the model, but is still taken into consideration. SOA modelled surroundings comprise of many services that involves a large amount of executables to perform tasks. Such a model can cause a single application to generate millions of executables. Managing and providing information on how services interact is a complicated task. Such an asynchronous logic becomes very complex for both the user and the machine. As SOA does not need logical thinking, the events that came before and are about to occur, are irrelevant for the SOA model. As a result, SOA finds it difficult to track activity.
The SOA model does not involve programs that are object oriented. The presence of such indistinctness renders the model obsolete, because of which the program gets locked into the event driven structure. SOA involves XML layers that require program analysis and composition. In the absence of binary code technology, the applications may run slower and require more working power, which increases costs. Besides, SOA does not possess the ability of integrated computer operations.The random accessing of memory is slow and deviates from the original plan of execution.
