Which design principle should be considered when architecting in the AWS Cloud?
Think of servers as non-disposable resources
Use synchronous integration of services
Design loosely coupled components
Implement the least permissive rules for security groups
Explanations:
In AWS, it is recommended to treat servers as disposable resources. This means designing for scalability and resilience, where instances can be terminated and replaced without significant impact on the application.
Synchronous integration can lead to tight coupling between services, making them less flexible and resilient. It is better to design systems that allow for asynchronous communication to improve decoupling and fault tolerance.
Designing loosely coupled components is a fundamental principle in AWS architecture. It allows for independent scaling, easier updates, and improved resilience, as components can fail without impacting others.
While implementing least privilege for security is important, security groups are typically designed to allow specific traffic rather than being set to least permissive rules by default. Best practices involve creating a secure network without necessarily making every security group as restrictive as possible.
