Question

A new application will run across multiple Amazon ECS tasks. Front-end application logic will process data and then pass that data to a back-end ECS task to perform further processing and write the data to a datastore. The Architect would like to reduce-interdependencies so failures do no impact other components.

Which solution should the Architect use?

Answer 1

To minimize interdependencies and failure impacts in an Amazon ECS application, the Architect should use a microservices architecture with an API Gateway, service discovery, and circuit breakers.

Step-by-step explanation:

To reduce interdependencies and minimize the impact of failures on other components in an Amazon ECS application, an Architect should implement a microservices architecture. By structuring the application as a collection of loosely coupled microservices, each ECS task will run independently.

This means if one service fails, it does not necessarily cause the other services to fail. To enhance this architecture, the Architect could incorporate an API Gateway to manage traffic and ensure smooth communication between the front-end and back-end ECS tasks.

Another recommendation is to use service discovery mechanisms to dynamically discover and communicate with other services or tasks in the ecosystem without hardcoding service endpoints. This approach improves flexibility and resilience as services can be added, removed, or modified without affecting the overall application flow.

Lastly, the Architect should consider implementing circuit breakers for each service interaction. Circuit breakers prevent failures from cascading to other services by cutting off the connection to the failing service, allowing the rest of the application to continue functioning normally while the issue is being resolved.
