If an Enterprise decides to go and adopt the Service Oriented Architecture and implement the change, it has to sure analyze and understand the Benefits of SOA and if it is really essential.
Here are some of the benefits or advantages of Service Oriented Architecture.
- Increased Intrinsic Interoperability
- Increased Federation
- Increased ROI
- Increased Organizational Agility
- Increased Vendor Diversification Options
- Reduced IT Burden
Increased Intrinsic Interoperability
Interoperability applies to sharing of data between the applications. The more interoperable they are, easier it is for them to exchange information. Applications that run in silo need to be integrated. Integration is a process that causes Interoperability
The goal of SOA is to have the interoperability built into the service thus eliminating the need for integration. Interoperability can be attained by decidedly applying the design principles and standards.
Federated IT Environment refers to one where applications and resources and combined and united but also their individual autonomy and self-governance is maintained. SOA strives to increase the federated aspect of the Enterprise environment. It does it by creating standardized and composable services, which creates a natural harmony across the enterprise between the applications and services.
Measuring the ROI of an enterprise solution can be difficult but it can be obvious when looked at from a long term perspective.
Traditional silo applications tend to grow over time and create complex environment which can be a very difficult to maintain and enhance.
SOA proposes creation of agnostic solution logic that can be used for multiple purposes, thus it has the benefit of re-usability. Re-usability of solution logic in services can increased ROI in long term
Increased Organizational Agility
Agility on the organizational level refers to its ability to quickly respond to a change. SOA is very much seeking to improve organizational agility.
When SOA principles are applied across the enterprise, it results in implementation of services which are standardized and reusable and agnostic to one particular business process and application environment. As these number of services increases, and request for new change can be easily met by reusing the existing services and developing on them as required. This results in quicker project delivery and quicker adaptation to changes.
Increased Vendor Diversification Options
By designing a Service Oriented Architecture in alignment with but neutral to major vendor SOA platforms and by positioning service contracts as standard endpoints across the enterprise, proprietary service implementation details can be abstracted. This enables the organization to have more options to diversify their enterprises as required.
Reduced IT Burden
Successfully applying the Service Oriented principles and designs results in an enterprise with reduced redundancy, reduced size and operational cost and reduced overhead. This can benefit the organization through dramatic increase in efficiency and reduction in cost.
Those are some of the benefits of Service Oriented Architecture.
