What and why?
Currently we have session affinity set to clientIP in a number of our apps including frontstage.
During performance testing it was discovered that one pod was serving all of the test script requests. Presumably because the requests are coming from a single sourceIP. It's not clear why session affinity was introduced and so the consequences of updating this need to be fully understood.
Options for session affinity:
Setting session affinity to none is not the same as removing the session affinity. None uses a 5-tuple hash (source IP address, the source port, the protocol, the destination IP address, destination port ). As the source ip is still included in this hash, we may need to remove the session affinity completely to prevent requests being served from a single pod when coming from a single source IP.
