What is SOA? 

Service Oriented  Architecture, also known as SOA for its acronym in English (Service-Oriented Architectures) , is a type of software architecture that allows its elements. Defines the use of services (concrete programs or tasks with a specific function) to support business requirements.

In conclusion, an SOA architecture allows the integration of software elements that are implemented and maintained separately, allowing them to communicate with each other and work together to form software applications in different systems.  

What characteristics identify an SOA architecture? 

  • The services are autonomous. Each SOA service is independently maintained and developed.  
  • The services are distributable. They can be located anywhere on the network as long as it supports the required communication protocols.  
  • Services can be broken down. Each SOA service is independent of the others and can be replaced or upgraded without breaking the applications it connects.  
  • Services do not share classes. In an SOA architecture, services share contracts and schemas when they communicate, not inner classes.  
  • Services are policy compliant. I understand policies as the definition of characteristics such as transport, protocol or security.  

How do I know the difference between SOA and Microservices? 

  1. Component sharing:   While Microservices minimize the sharing of components across the network, SOA takes full advantage of it. Something that impacts the latency of the environment, making SOA-based systems slower.
  2. Service granularity:  In an SOA architecture, services are more versatile in terms of their business functionality, while Microservices are made up of highly specialized, single-purpose services. 
  3. Coordination:  In an SOA architecture, it is necessary to coordinate with various groups to attend to business requests, while Microservices are generally not coordinated with each other. 
  4. Middleware:   Microservices work with an API layer created between services and service consumers, while a SOA architecture it uses Middleware for its communication, a fact that adds additional capabilities such as mediation and routing, message enhancement, messages and transformation of protocols, etc. 
  5. Heterogeneous interoperability:   If our goal is to achieve the integration of various systems using different protocols in a heterogeneous environment, the best option is an SOA approach. However, a microservices approach will be preferable if all services can be exposed and the same remote access protocol must be used, as with Microservices, we try to simplify the architecture pattern by reducing the number of integration options.  

What are the benefits of implementing an SOA architecture in a company? 

  1. Increase the alignment between business and technology.  The SOA perspective promotes cooperative work between business and IT teams, unlike more traditional models for project management, which are based on business units that express their needs to IT areas for implementation.  
  2. Increase the ROI of IT initiatives.   An SOA approach allows solutions to be created in less time and at a lower cost, since, for example, an SOA approach proposes that the functionalities common to the business must be reusable: the functionality is developed once and is reused for whatever is needed.  
  3. Increases organizational agility.  The cooperation between IT and business teams allows them to seize and create market opportunities in a more agile way.  
  4. We reduce the operational burden of IT: We reduce the cost of maintenance, administration, and development efforts with the standardization and normalization of services.  
  5. We increase interoperability. We promote transparent communication without intermediaries, which allows us to reduce integration efforts in the different systems of the IT environment.  
  6. Increases association:  Improves the ability to distribute and organize the company into logical units that can function independently, as long as they comply with the same government policies and guidelines, thus allowing the company and its departments to evolve quickly. 

If in your company you are considering implementing a project for the adoption of an SOA architecture or any other that involves your ICT infrastructure, at services we can help you with its implementation and start-up. Contact us and our advisors will contact you as soon as possible.
