How does SFCC support microservices architecture?

Salesforce Commerce Cloud (SFCC) supports microservices architecture primarily through the integration of independent services via APIs. This approach allows different services to communicate and interact without being tightly coupled to one another, which is a hallmark of microservices architecture.

In a microservices environment, each service can be developed, deployed, and scaled independently. This not only increases flexibility but also enhances the overall resilience of the application, as issues in one service do not impact others. By leveraging APIs, SFCC allows developers to create modular applications where services can be added or modified without requiring significant changes to the entire system.

The focus on API connectivity aligns with modern development practices, enabling businesses to integrate third-party services or systems more easily, customize their solutions, and innovate faster. Thus, the use of APIs represents a fundamental principle of microservices architecture, which is effectively utilized within SFCC.

Other options do not support the microservices concept effectively. Direct database access would create tight coupling between services and the data layer, which contradicts the modularity principle. Monolithic application techniques imply a single deployment unit, which is the opposite of the decentralized nature of microservices. Furthermore, limiting service connections would hinder flexibility and scalability, essential components of a microservices architecture.
