All About Google Cloud Load balancer Sticky session

Session stickiness or session persistence is responsible for the load balancer creating an affinity between a client and a particular network server. In fact, sticky sessions come in handy in improving user experience as well as optimizing resource usage.

According to our experts, a load balancer assigns a specific attribute to a user by issuing cookies or tracking its IP details. Furthermore, the load balancer can route all the requests of the user to a particular server during the session as per the tracking ID.

With the sticky session feature extended to the Google Cloud HTTP(S) Load balancer. In fact, the session affinity can be either by Client Cookie or Client IP. In fact, HTTP(S) offers different types of session affinity as seen here:

• Client IP affinity
• Header field affinity
• Generated cookie affinity
• HTTP Cookie affinity
• No Session affinity is set

Additionally, sticky sessions may make it difficult to keep servers in balance. An overloaded server accumulates too many sessions if some sticky sessions require more resources. This may cause the load balancer to shift a client to another server mid-session causing data loss.

Session stickiness offers the following benefits:

• Minimized data exchange

  Servers in the network do not need to exchange session data.
• RAM cache utilization

  It offers better utilization of the application’s RAM cache, leading to better responsiveness.
