Final answer:
To coordinate calls between multiple AWS Lambda functions, you can use synchronous or asynchronous invocation. Combine Lambda functions with AWS Step Functions or Amazon EventBridge for effective coordination and orchestration.
Step-by-step explanation:
To coordinate calls between multiple AWS Lambda functions, you can use two approaches: synchronous or asynchronous invocation. Synchronous invocation allows one Lambda function to directly call another and wait for the response before continuing.
This is useful when the functions depend on each other's results. On the other hand, asynchronous invocation involves one function triggering another without waiting for the response, making it ideal for loosely coupled operations.
In both cases, you need to combine Lambda functions with services like AWS Step Functions or Amazon EventBridge to effectively manage coordination and orchestration between functions. These services provide features such as state machines, workflows, and event-driven architectures to help you coordinate and sequence the execution of multiple Lambda functions.
