AWS Certified Developer Associate DVA-C02 Practice Question
A developer is designing a new cloud-native application. To ensure the application is resilient, scalable, and easy to maintain, individual services should be able to be updated independently without affecting other services. Which design principle should the developer primarily follow to achieve this goal?
A loosely coupled design reduces the interdependencies between components in a system. This allows individual components or services to be developed, deployed, and scaled independently, which enhances the overall flexibility, resilience, and maintainability of the application. Tightly coupled designs, in contrast, have strong dependencies that make changes difficult. Monolithic design often results in a tightly coupled system. Stateless design is a related but different concept, focusing on not storing session data on the server between requests.
