[All DevOps SRE Questions]

Microservices are independent services that are developed, deployed, and maintained separately.

Which of the following BEST justifies the use of this application architecture?

Show Suggested Answer Hide Answer
Suggested Answer: A

Comprehensive and Detailed Explanation From Exact Extract:

SRE supports microservices architecture because it improves reliability by reducing blast radius, allowing independent deployments, and enabling scalable autonomous teams. The SRE Book notes: ''Microservices enable teams to independently iterate and improve reliability without the constraints of large monolithic systems.'' (SRE Book -- Distributed Systems). One of the strongest reasons to adopt microservices is modernizing and refactoring large legacy monoliths, allowing them to be broken into independently deployable, maintainable components.

Option A is therefore the best justification.

Options B, C, and D may involve architectural choices, but they do not explain why microservices are the preferred architecture for reliability and scalability.

Thus, A is correct.

Wait, can microservices really help with UI modernization? Seems off.

I lean towards A as well, but I wonder if C could apply in some cases where simplicity is key.

I practiced a question similar to this, and I think D makes sense for quick iterations, but it doesn't really capture the essence of microservices.

I'm not entirely sure, but I feel like B could also be relevant since a better UI might need a different architecture.

I remember we discussed how microservices help with modernizing legacy systems, so I think A might be the right choice.
