Which solution will meet these requirements?
Use an Amazon Simple Queue Service (Amazon SQS) queue to store events and invoke the Lambda function.
Use an AWS Step Functions state machine to pass events to the Lambda function.
Use an Amazon EventBridge rule to pass events to the Lambda function.
Use an Amazon Simple Notification Service (Amazon SNS) topic to store events and Invoke the Lambda function.
Explanations:
Using Amazon SQS allows decoupling of the service calls. Events can be queued and processed by Lambda, ensuring all calls are eventually completed even if third-party services experience delays.
AWS Step Functions can manage state and workflow, but they do not inherently decouple calls like SQS. While they can handle asynchronous workflows, they are not designed primarily for decoupling third-party service calls.
Amazon EventBridge is primarily for event-driven architectures and does not provide the queueing mechanism necessary for decoupling service calls. It can trigger Lambda functions but does not ensure message durability.
Amazon SNS is a publish/subscribe service and is not designed for ensuring message delivery like SQS. It does not provide the queueing mechanism necessary to handle asynchronous th
As I see it, the answer is:
Use an Amazon Simple Queue Service (Amazon SQS) queue to store events and invoke the Lambda function.
