Question - Explain Connection Draining
Answer -
Connection Draining is an AWS service that allows us to serve current requests on the servers that are either being decommissioned or updated.
By enabling this Connection Draining, we let the Load Balancer make an outgoing instance finish its existing requests for a set length of time before sending it any new requests. A departing instance will immediately go off if Connection Draining is not enabled, and all pending requests will fail.
