For years, monolithic systems were the dominant option due to their ease of development and deployment. However, with the rise of digital business, the need for greater flexibility and scalability drove the adoption of microservices-based architectures .
Microservices brought with them multiple benefits, such as the ability to scale services independently. However, they also introduced significant challenges: managing a large number of services, communicating between them, and the operational complexity resulting from monitoring, logging, and distributed deployments.
To address these challenges without compromising the benefits of both approaches, the Selective Service-Oriented Architecture (SSOA) approach emerges . This hybrid architecture balances the country email list modularity of a monolith with the scalability of microservices, allowing businesses to evolve their architecture as needed without the operational overhead of full-blown microservices.
What is Selective Service-Oriented Architecture (SSOA)?
Selective Service-Oriented Architecture (SSOA) is an architectural pattern that combines the simplicity of a modular monolith with the flexibility of microservices. Its central principle is selective extraction , meaning that only those components that require scalability or greater autonomy are externalized as microservices. The rest of the system remains a modular monolithic core focused on the organization's key functionalities, ensuring ease of maintenance and operation.
Instead of breaking down the entire application into microservices from the ground up, SSOA allows you to evolve the architecture progressively , identifying which parts of the system require independence and scalability. For example, modules such as authentication, payment processing, or real-time analytics can be extracted as microservices without unnecessarily fragmenting other areas of the system.
