Why Is Service Oriented Architecture Important

Service-oriented architecture (SOA) is an increasingly popular way for businesses to reduce time-to-market and streamline operations. It is quickly becoming the go-to architectural model for enterprise-level operations. The reason for this is that it lends itself well to agile development, streamlining processes and facilitating the efficient production of the goods and services needed to meet customer expectations.

At its core, SOA is a methodology for developing applications and services by breaking complex tasks into modular components. This modularity allows developers to create services with maximum reuse, meaning they are limited only by their own creativity. This concept of ‘building applications from components’ has been around for a long time, but SOA takes it to the next level by making components more self-contained and agnostic to infrastructure. This dramatically simplifies the structure of an application, enabling the easy scalability and reuse of components.

The use of SOA allows hundreds or even thousands of services and components to be tied together in a single application. By using SOA, developers can efficiently combine all these components into a larger service stack. This service stack is also very easy to maintain, since developers can quickly recognize and isolate any faulty components. SOA is also very flexible, since it enables developers to create single-function components that are not dependent on the rest of the application.

SOA is also known for improving integration. It can easily tie together different types of information from different sources. For example, an SOA system can integrate customer information from multiple data sources and offer a single customer view. This makes it easy for customer service reps to get a quick view of a single customer and make decisions based on a unified source of data.

Security is another area where SOA shines. It is designed to protect applications and services against unauthorized access. This is achieved by providing a secure ‘tunnel’ through which all traffic is routed. This tunnel enables applications to be securely transmitted and received, while protecting them from malicious attacks.

Finally, SOA also helps businesses reduce operational costs. By using SOA to create a reliable architecture, businesses can remove duplicated services and eliminate redundant systems. This reduces maintenance costs, since fewer computers and servers need to be managed and maintained.

Benefits for Businesses

The use of SOA can provide many benefits for businesses. One of the main benefits is that it can help to accelerate the development process. By breaking complex tasks into smaller and more manageable pieces, developers can quickly build applications that meet customer requirements. Additionally, the modularity of SOA also helps to ensure that the application is of high quality.

Another benefit of SOA is that it can provide a platform for rapidly deploying new services and components. SOA makes it easy for developers to quickly add components and services to an application, allowing it to quickly adapt to changing market conditions. This flexibility also makes it easier to integrate with legacy systems, allowing businesses to capitalize on existing investments.

Finally, SOA can help to improve customer satisfaction by providing users with an efficient and effective way to interact with the application. By breaking the application down into smaller components, users are able to find the specific services and functions they need without having to navigate the entire application. This improves the user experience and makes it easier for customers to find and consume the services they need.


In summary, SOA has shown to be an excellent way for businesses to speed up their operations, reduce costs and increase customer satisfaction. It is quickly becoming the standard for developing enterprise-level applications, and it will likely remain so for the foreseeable future.

Advantages of SOA

The advantages of SOA are many, but the most significant benefit is undoubtedly its scalability. By breaking complex tasks into smaller components and allowing them to be reused, developers can rapidly build applications and services. This scalability also allows applications to be easily extended and updated, ensuring they can quickly adapt to changing customer requirements. Additionally, the use of SOA also helps to improve integration, security and reduce operational costs.

Business Case for SOA

The business case for utilizing SOA as an architectural platform is clear – it is more efficient, cost-effective and reliable than traditional approaches. The ability to quickly develop applications and scale them up to meet customer requirements has proven to be a major benefit for businesses. Additionally, the modularity of SOA means that applications can be easily maintained and extended, allowing them to meet ever-changing customer needs. Finally, the improved integration, security and reduced operational costs provided by SOA make it an ideal solution for modern businesses.

Alternatives to SOA

Although SOA is the preferred architectural model for enterprise-level applications, there are a variety of alternatives that can also be used. For example, microservices are becoming increasingly popular as a way to break down monolithic applications into smaller components. Additionally, there are also a variety of NoSQL databases available which can offer high performance for applications with large datasets. Finally, serverless computing is also emerging as an alternative to traditional applications, allowing developers to quickly develop, deploy and scale applications without having to manage servers.
