SOA is an architectural model that allows to decree a structuring and a work fence for information systems, optimizing the reuse of code between processes, reducing the number of errors that are produced by the excess of data, and delivering results in standard formats. Along with service-oriented architecture examples like the Web Services (WS), which correspond to services whose importance is based on how it communicates through web channels using the standard language (WSDL) and a defined message model (SOAP).
Currently, companies have customized information systems designed to support each specific business area, whose origin in many cases corresponds to solutions implemented through different technologies, creating entire islands in terms of resource and information management.
Why should I implement SOA in my company?
The problem arises when operating between systems from different domains is necessary to achieve a common goal. In these cases, companies usually have integration processes that allow communication between the large systems that manage the core of the business, for example, to know the actual situation of the operational processes that support the information systems, critical components in the administrative tasks, and management decision making. At this point, it becomes essential to provide an inter-organizational software architecture that focuses on developing an enterprise application strategy that facilitates their integration and motivates the creation of services, rather than applications in which the final application simply manages the execution of a set of these services, adds its particular logic and presents an interface to the end-user in a standard way.
The SOA architecture proposes a much more efficient model, where the function’s code.
It is independent of how the integration is resolved; the function can be created in any programming language and reside on any technological platform in SOA. The architecture consists of three parts: a provider, an intermediary, and a client, between which there is no coupling.
Types of Service-Oriented Architecture.
This section presents some of the best options for service-oriented architectures. These options serve as a basis for the actual architecture types that can be added. The two options offered are data-centric architecture and distributed processing.
- Data-centric SOA.
This architecture is based on moving data to where it is needed. It does this with a message router and the data most requested by different services.
- Distributed Process SOA.
- The alternative to data-centric SOA is a distributed process architecture. It is called distributed because the process occurs in multiple locations, corresponding to any place where the system has data or process requirements.
- Reduces complexity with standards-based support compared to point-to-point integration.
- Reuses previously deployed shared services.
- Integrates with legacy applications, limiting maintenance and integration costs.
- Facilitates development because applications are reusable, easier to maintain, and can extend system functionality, making them securely available.
Service-oriented architecture examples are a new, and this discipline was devised from the first information systems created by establishing various ideas that have evolved. Today, it is vital to operate with a structure that optimizes every aspect of the business to compete in the market.
