AWS Certified Cloud Practitioner — Question 314

Using Amazon Elastic Container Service (Amazon ECS) to break down a monolithic architecture into microservices is an example of:

Answer options

• A. a loosely coupled architecture.
• B. a tightly coupled architecture.
• C. a stateless architecture.
• D. a stateful architecture.

Correct answer: A

Explanation

Deconstructing a monolith into microservices with Amazon Elastic Container Service (Amazon ECS) reduces interdependencies, resulting in a loosely coupled architecture where components can be developed and scaled independently. Tightly coupled architectures have high dependencies between components, while stateless and stateful designs refer to how session data is managed rather than how services are integrated.
