Lambda invocation ways
◉ Event (async)
○ Lambda function doesn’t send
a response back to the event
source.
○ Events are queued before
being used to invoke the
Lambda function (retry
policies)
○ Used by S3, SNS
◉ Request-Response (sync)
○ Forces Lambda to execute the
function synchronously and
return the response to the
caller.
○ Used by API Gateway, AWS
Console, AWS SDK, etc.
