Does AWS network load balancer support sticky sessions?

Last updated on September 25, 2022 @ 6:38 pm

PRO TIP: Yes, AWS network load balancer does support sticky sessions. However, you should be aware that there are some potential issues that can occur when using sticky sessions. These include:

1. increased latency due to the need to route traffic through the load balancer;

2. potential for increased costs if your traffic volume is high;

3. possible security risks if sticky sessions are not properly configured.

AWS network load balancer (NLB) supports sticky sessions, which allows a client to remain connected to the load balancer even if the client’s session is inactive for a predefined amount of time. This helps to keep the load balancer up and running and reduces the need for the client to re-authenticate when it reconnects.
