Learn what is service oriented architecture and its advantages and disadvantages?

Service-oriented architecture’s definition has always been a moving target. It evolved for several years before they published a white paper in 2007. Later, that paper grew into the due to its fragmented past, SOA has more than one definition. Service Oriented Infrastructure (SOA) is the organization of the components of a system according to the services they provide. The provider of the service and the requester are loosely coupled within the architecture allowing the services to operate independently of the platform on which they will be used. It is an approach to designing software in which components are arranged according to business processes.

These services are small functions which fulfill a specific task. They are well defined, self-contained, and fully functional programs. Think of the removable batteries we use in our devices. They may be used in a remote control, shaver, or children’s toy. Their functionality and ability to provide power are not only independent of the environment in which they are implemented, but also unaffected by other connected components. They provide a service.

Organizations use varying computer architectures with each having their respective advantages and disadvantages. We will now examine the advantages and disadvantages of Service Oriented Architecture.

Advantages

·         Services are Reusable

The services provided or requested are complete, self contained programs they are characterized by their reusability. Someone has already created the scissors. Why would someone else try to create their own if they needed to cut fabric services are reused many times in different applications irrespective of the other interacting components in that system. Let’s take a currency converter for example. Not only do financial websites use them, but popular blogs and websites add these services to make their content diversified, giving the user space to do different things.

·                  Services are Easily Maintained

Editing and updating any service implemented under SOA architecture is easy. You don’t need to update your system. Service is maintained by a third party and any amendment in this service won’t have an effect on your system. In most cases previous API work because it is functioning before.

·         Reliability

Services square measure typically tiny size as compared to the fulfledged application so it’s easier to correct and check the freelance services. SOA services are complete and selfcontained programs. This makes it easy for testing, debugging or any form of maintenance.

·         Availability

Services have an equivalent directory structure so customers can access the service information from an equivalent directory on every occasion. If any service has modified its location then additionally directory remains the same. This is very helpful for consumers.

·         Scalability

Any service obtaining several users then it is often simply scalable by attaching additional servers. This will create service out there all time to the users.  Ability of services to be successfully run on different servers within an environment increases the scalability and availability of the service.

·         High Quality Services

Providing a high quality service to the customers and servers the customer data will be in consistent and they are maintained in a high manner with great security.

• Directory Structure

Services have an equivalent directory structure so customers can access the service information from an equivalent directory on every occasion. If any service has modified its location then additionally directory remains the same. This is very helpful for consumers.

·         Increased Productivity

Services generated using SOA principles are independent of each other. So services are often utilized by multiple applications at an equivalent time service that have been versatile.

Disadvantages

• High Bandwidth Server

As therefore net service sends and receives messages and knowledge often times so it simply reaches high requests per day. So it involves a high-speed server with plenty of information measure to run an internet service.

• Extra Overload

In SOA, all inputs square measures its validity before it’s sent to the service. If you are victimization multiple services then it’ll overload your system with further computation.

• High Cost

It is expensive in terms of human resource, development, and technology. It is not affordable to many people.
