A
Think parallel
B
Implement elasticity
C
Stop guessing capacity
D
Decouple components

Explanation
The correct answer is Decouple components because:
-
Microservices architecture is fundamentally based on the principle of decoupling components - breaking down applications into smaller, independent services that can be developed, deployed, and scaled separately
-
Decoupling allows each microservice to function independently, communicate through well-defined APIs, and be maintained without affecting other services
-
This aligns with AWS Well-Architected Framework's design principle of building loosely coupled systems
Why other options are incorrect:
-
Think parallel: Focuses on parallel processing and concurrent operations, not specifically on microservices architecture
-
Implement elasticity: Refers to scaling resources up and down based on demand, which is important but not the core principle for microservices
-
Stop guessing capacity: Relates to capacity planning and right-sizing resources, not the architectural pattern for microservices
Decoupling components enables the independent development, deployment, and scaling that defines microservices architecture.
