SOA-Service Oriented Architecture
A service-oriented architecture (SOA) is an architectural pattern in computer software design in which application components provide services to other components via a communications protocol, typically over a network. The principles of service-orientation are independent of any vendor, product or technology.
- A service-oriented architecture is essentially a collection of services.
- These services communicate with each other.
- The communication can involve either simple data passing or it could involve two or more services coordinating some activity.
- Some means of connecting services to each other is needed.
- Service-oriented architectures are not a new thing.
- The first service-oriented architecture for many people in the past was with the use DCOM or Object Request Brokers (ORBs) based on the CORBA specification.
SOA Stands for Service oriented architecture
- SOA is a software architectural pattern
- SOA is an approach to developing enterprises systems by loosely coupling interoperable services
- Service orchestration is the main theme that makes SOA work
Backbone of SOA is a service
Service is a self contained, re-usable unit of software that can execute a particular task and that can be invoked from multiple systems developed in various platforms. For instance, retrieving your bank account balance.
If a service-oriented architecture is to be effective, we need a clear understanding of the term service. A service is a function that is well-defined, self-contained, and does not depend on the context or state of other services.
Application or service orchestration is the process of integrating two or more applications and /or services together to automate a process.
SOA Based Integration platform
- Insurance claim application (Client app)
- Customer service
- Claim validity service
- Balance status service
- Debit balance service
SOA helps in the following scenarios
- SOA helps identify functions used by multiple systems or applications and bundle them into reusable, self – contained services.
- SOA promotes using standards, which is critical in any integration because standards create a common baseline for all parties to work on.
- SOA enhances the integration capability with the flexibility to plug in, change, or update services almost seamlessly to clients with SOA’s decoupling capabilities.
- Some organisations aren’t willing to give up their tried and tested technologies. In these cases, SOA can help by wrapping legacy applications in standardized ways, enabling their exposure in a standards based environment suited for integration and reuse.
- Applications are loosely coupled
- Location transparency
- Improved Testability
- High availability
