Which of the following is an architectural design principle of the AWS Well-Architected Framework?
A
Loosely couple components
B
Build monolithic systems
C
Scale vertically, not horizontally
D
Use third-party software
Explanation:
The AWS Well-Architected Framework emphasizes loose coupling as a key architectural design principle. Loose coupling allows components to be developed, deployed, and scaled independently, making the system more resilient and easier to maintain. This contrasts with monolithic systems (option B), which are tightly coupled and harder to scale and maintain. Horizontal scaling (option C) is preferred over vertical scaling in cloud environments, and while third-party software (option D) can be used, it's not a core architectural principle of the framework.
