Stateless services and sticky sessions
Why do horizontally scaled stateless web services generally avoid sticky sessions?
Options
- 1Because session state stored in a node's memory cannot be served by other nodes after a failover or scale event
- 2Because the load balancer would hash on the client IP, which shifts behind NAT and corporate proxies
- 3Because HTTP is connectionless by design and therefore cannot persist cookie state across separate requests
- 4Because binding a client to one node would permanently double that node's memory footprint for every request
