Session Persistence
Consistent hashing also allows for session persistence (or “sticky sessions”), where requests from the same client are consistently routed to the same backend server. This is useful for maintaining stateful connections, such as in web applications that require users to stay connected to the same server for the duration of their session.
Overall, consistent hashing in load balancers provides a scalable and efficient way to distribute traffic across backend servers while maintaining a degree of consistency and minimizing disruptions during server additions or removals.
Is Consistent Hashing used in Load Balancer?
Yes, Consistent Hashing is commonly used in load balancers to distribute traffic across a set of backend servers or nodes.
Below is an explanation of how it works:
