Invocation models

  • Synchronous. Service waits for the result returned by Lambda.
  • Asynchronous. Fire and forget model. Service waits for acknowledgment from Lambda that the message received, and then continues with its own execution.
  • Poll based. Lambda polls on your behalf

Integrations with other services
