SOA encompasses a set of design principles that structure system development and provide means for integrating components into a coherent and decentralized system. SOA-based computing packages functionalities into a set of interoperable services, which can be integrated into different software systems belonging to separate business domains.
There are two major roles within Service-oriented Architecture: Service provider: The service provider is the maintainer of the service and the organization that makes available one or more services for others to use. To advertise services, the provider can publish them in a registry, together with a service contract that specifies the nature of the service, how to use it, the requirements for the service, and the fees charged.
Service consumer: The service consumer can locate the service metadata in the registry and develop the required client components to bind and use the service. Skip to content. Change Language.

Service Reusability divides the services with the intent of reusing as much as possible to avoid spending resources on building the same code and configurations.
Service Statelessness whereby services do not withhold information from one state to another in the client application. Service Composability breaks down larger problems into smaller elements, segmenting the service into modules, making it more manageable.
Service Interoperability governs the use of standards e. XML to ensure larger usability and compatibility. A service-oriented architecture SOA works as an components provider of application services to other components over a network. Service-oriented architecture makes it easier for software components to work with each other over multiple networks.
Service-oriented architecture is implemented with web services based on WSDL and SOAP , to be more accessible over standard internet protocols that are on independent platforms and programming languages. Service-oriented architecture has 3 major objectives all of which focus on parts of the application cycle: 1 Structure process and software components as services — making it easier for software developers to create applications in a consistent way. Microservices architecture software is largely an updated implementation of service-oriented architecture SOA.
The software components are created as services to be used via APIs ensuring security and best practices, just as in traditional service-oriented architectures. Service oriented architecture has a testing phase so that the end is satisfied in terms of the quality of the product. Service oriented architecture testing is not limited to layers and web service, it is the overall testing of the whole architecture.
The testing process is within three layers in architecture: Service Consumers, Process Layers, and Service layers. Testing can be divided into four different tiers:. A broker may be public or private. A service requester finds a service in a service broker or service registry and then will connect with the service provider to receive the service. The concept of services introduced by service-oriented architecture has become what is now a central component of modern cloud computing and virtualization in things like middleware and microservices.
Because of their similarities, SOA and microservices architecture are often confused. The main characteristic that can help differentiate between them is their scope: SOA is an enterprise-wide approach to architecture, while microservices is an implementation strategy within application development teams. They also communicate to their respective components differently, with SOA using an ESB while microservices can communicate with each other statelessly, through language-agnostic APIs.
The language-agnostic aspect of APIs in microservices also allows dev teams to choose what tools they want to work with. In these ways, microservices can be more tolerant and flexible. SOA is also sometimes confused with Software-as-a-service. SaaS is a form of cloud computing that delivers a cloud application—and all its underlying IT infrastructure and platforms—to users. Users interact with the software through a web browser on their computer or mobile devices. Because of advancements in container technology, microservices have become the foundation for cloud-native applications—loosely-coupled microservices that are deployed in Linux containers and connected through APIs or a mesh network for message routing.
