SOA stands for Service Oriented Architecture and it is this architectural set up that aids in better performance and efficiency. SOA is like a really good delegator of work. In a setup where each system has its own unique set of requirements and working, SOA steps in to delegate work in an effective way. By streamlining the process and narrowing down each system so that it functions perfectly within its own set of output goals, SOA helps achieve maximum utility and efficiency.
In today’s time, the demands of the market on the IT sector are huge and ever increasing. The need is to create an interface that is both customer friendly as well as manageable. Where SOA steps in, is in this niche position where it caters to the needs of both IT and commerce. A common example would be banking services. If a customer needs to access a certain banking service he just logs into the site and the SOA system, working behind the operation of the service, will the customer to the appropriate service. These banking services could be some independent services that are not specifically coded for any particular bank. Instead some common services could handle similar operations for all the banks, based on the input parameters. This is a huge advantage of SOA.
SOA’s flexibility is one of the key features that will ensure its longevity. Over time, each business has to adapt, mould and accommodate changes. If a service has to be changed, it can be done easily as most of them exist as web services that are loosely coupled and just need to be linked. This ease of access and of change ensures that SOA has advantages that cannot be ignored or undermined. But it is also a reality that SOA, like all other IT services, will be built upon and improved.
What works against SOA is exactly its vast extent of utility. This means that most of the people who end up using SOA are not sure of how exactly to implement it efficiently. It is because they comprehend the product’s utility but not it’s functioning. This leads to underachieved potential for the product itself. SOA needs to become more agile and lighter with times. The bulkiness of the system needs to be greatly reduced in order to extract maximum benefit out of SOA.
Because SOA is essentially an architecture, it is imperative that the companies design their own web layouts accordingly. This also means that if SOA is not employed accurately, it could do more harm than good. It increases cost and complexity whereas it is meant to reduce both. Therefore a major flaw of SOA is its prerequisite demand for an organized system. If employed on a system that is already in a state of chaos, then SOA could prove detrimental.
With the given set of uses and drawbacks, it is clear that SOA is not a one-time wonder. Its technological reservoir is something that is needed today and tomorrow.
