AWS Lambda is a serverless compute service that can run code in response to predetermined events or conditions and automatically manage all the computing resources required for those processes. Customizing and connecting these services requires code. What is AWS Lambda? Where does Lambda fit in the AWS ecosystem?

Faster detection of a bad connection is accomplished when there’s a lower value, while latency or intermittent network issues may be better served by increasing it slightly – although overly long timeouts can result in application hang-ups with little chance for an established link. The latter refers to how long a socket can remain inactive.
