What is a fundamental trait of Microservices architecture?

The fundamental trait of Microservices architecture is the ability to deploy smaller, interconnected services independently. This architectural style breaks down applications into manageable services that can be developed, deployed, and scaled individually. Each service typically runs in its own process and communicates with other services through APIs, which enhances modularity and allows development teams to work on different services simultaneously without affecting one another. This independence facilitates faster deployment cycles, better resource utilization, and makes it easier to adopt new technologies or upgrade individual components without the risk of impacting the entire system.

In contrast, options discussing dependency on a monolithic codebase, centralization of application logic, and unified data management do not align with the core principles of Microservices. Monolithic architectures are the opposite of microservices, as they centralize code in a single unit. Centralization of logic and data management also contradicts the decentralized nature of microservices, where each service may manage its own data independently, promoting flexibility and resilience.
