The Standards in Utilization Of SOA
Like any standards that are being proposed, SOA, or Service Oriented Architecture, has its own set of requirements so that any system can be made to interface properly with all other SOA enabled systems.
There are varying degrees of these requirements and depending on what your network is using, you may need to uprate or upgrade certain aspects of the hardware or software to comply with the SOA initiative.
Simply put, the requirements for using SOA is more how a typical software application is structured rather what command it uses. More often than not, there are certain built in external translators that these software may already contain and that it only needs and external system to make full use of its capability.
Certain sets of requirements for SOA system integration refers to how the application was designed. You may hear terms like granularity, service contract, service loose coupling, and so on that refers to how independent these software programs can be with respect to other software programs that are being used within its bounds.
Plainly put, a typical program that operates within this standard can be operated with minimal external dependencies. This means that this particular program must be able to function within its own operating space with minimal external systems being employed to make it function properly.
Another requirement that SOA needs is how a system can operate using reusable logic. Most software programs have single use programming logic built into them. This means that this logic is only good for examining and deciding on a single aspect of the operation of the program itself. With reusability, the design of the program is such that a lot of its core logic systems can be used any number of times by any different systems within the program. This makes the program more compact and limits wasted space for use in other things.
Other things that SOA require are systems to be adaptable, autonomous, engaged in a loose form of communication agreement with other systems and what can be called the ability of a system to handle unforeseen unprogrammed variables. Being adaptable means that the system must be in such a way that it is built with as many systems that it may encounter in its service life and use it to its maximum potential.
Being autonomous means that a system that uses SOA has the logic to decide on their own what it needs to do. This does not mean that it has to have artificial intelligence, it only means that it know enough of what the system is to be able to use it effectively.
The last one generally means that a system has to be built in such a way that it may react favorable or logically when it encounters a scenario that it was not programmed for. Much like those self-learning systems, not just robots, but computers systems that have the built in programming to get around a particular problem that it was not programmed for. SOA currently still has many things to be debated upon when it comes to what final requirements are to be used for the future SOA standards.
