问题 I have an ELB and 3 nodes behind it. Can someone please explain me what will ELB do in these scenarios: Client Request -> ELB -> Node1 fails in the middle of the request (ELB timeout) Client Request -> ELB -> Node1 timeouts (Server timeout and health check haven't kicked in yet) Particularly I'm wondering if ELB retries the request to another node? I made a test and it doesn't seem to, but maybe there's a setting that I've missed. Thanks, 回答1: The AWS Elastic Load Balancing service uses
