What is microservices architecture and its advantage in MDC3?

• A. Monolithic architecture
• B. Microservices architecture decomposes apps into small, independently deployable services that communicate via lightweight protocols; advantages include scalability, fault isolation, and faster deployments in MDC3.
• C. A database design
• D. A data visualization approach

Answer: (B)

Microservices architecture is about breaking an application into small, independently deployable services that communicate with each other through lightweight protocols such as HTTP/REST or messaging. This arrangement lets you scale just the parts that need more resources, limits the impact of a failure to the specific service that encounters the issue (fault isolation), and enables faster deployments because only the affected service needs updating rather than the entire application. In MDC3, these benefits translate to greater agility, resilience, and faster release cycles across teams, which is why this approach is favored. The other options describe unrelated concepts like a monolithic architectural style, a database design, or a data visualization approach, which don’t capture how the system is structured and deployed in MDC3.
