Which architectural pattern is Sitecore XM Cloud built on?

• A. Monolithic architecture
• B. Microservices architecture
• C. Layered architecture
• D. Serverless architecture

Answer: (B)

Sitecore XM Cloud is built on a microservices architecture, which is characterized by being composed of small, independent services that communicate with each other through well-defined APIs. This architectural pattern allows for greater scalability, agility, and flexibility, as each microservice can be developed, deployed, and scaled independently.

In a microservices approach, each component of the application can be managed and updated without affecting the entire system, making it easier to implement changes and improvements. This is particularly beneficial for the dynamic needs of content management and delivery that Sitecore solutions address, allowing businesses to rapidly adapt to changing demands and technology landscapes.

By embracing this architecture, Sitecore XM Cloud can offer improved performance, fault isolation, and the ability to use different technologies across various services, which is essential for delivering a modern digital experience that integrates seamlessly with other systems and services.
