Which AWS services can a company use to achieve a loosely coupled architecture? (Choose two.)
Which AWS services can a company use to achieve a loosely coupled architecture? (Choose two.)
To achieve a loosely coupled architecture, it is important to use services that facilitate asynchronous communication and workflow orchestration. Amazon Simple Queue Service (Amazon SQS) is a fully managed message queuing service that allows components of a distributed application to communicate asynchronously, decoupling the sender and receiver components. AWS Step Functions, on the other hand, is a serverless function orchestrator that coordinates and sequences various AWS services into serverless workflows, enabling scalability and resilience while maintaining loose coupling between components. Therefore, the appropriate services to achieve a loosely coupled architecture are Amazon SQS and AWS Step Functions.
**B. Amazon Simple Queue Service (Amazon SQS):** SQS is a fully managed message queuing service that enables decoupling of the components in a distributed system. It allows components to communicate asynchronously, promoting loose coupling. **E. AWS Step Functions:** Step Functions is a serverless function orchestrator that allows you to coordinate multiple AWS services into serverless workflows. It helps in creating loosely coupled, flexible systems by defining workflows that connect various services. So, the correct choices are B and E.
To achieve a loosely coupled architecture, services that enable asynchronous communication and decouple components are essential. Two services that support this goal are: B. Amazon Simple Queue Service (Amazon SQS): SQS is a fully managed message queuing service that allows components of a distributed application to communicate asynchronously. It helps decouple the sender and receiver components, providing flexibility and fault tolerance. E. AWS Step Functions: AWS Step Functions allow you to coordinate and sequence AWS services, including Lambda functions, in a serverless workflow. It helps in creating workflows that are scalable, resilient, and loosely coupled. While options A, C, and D (Amazon WorkSpaces, Amazon Connect, and AWS Trusted Advisor) are useful in various scenarios, they do not specifically contribute to achieving a loosely coupled architecture as directly as SQS and Step Functions.
