What is session means here?
Why are we load balancing wrt to session?
Please explain with example
Hi Sumit.
Here are answer to your questions:
- In client-side load balancing for Twitter, “session” refers to a unit of interaction or connection between a client and a server which represents the duration of time during which a client interacts with a particular server.
- Load balancing distributes incoming requests across multiple servers to prevent any single server from overloading. However, if sessions are not considered, a user’s requests might bounce between different servers, leading to a disjointed experience.
Example: Let’s say a user logs into Twitter and starts browsing their timeline. Initially, their session is directed to Server A. As they continue using Twitter, they decide to post a tweet. Now, instead of directing this request back to Server A, which might already be handling a high load of other requests, the client-side load balancer redirects the tweet-posting request to Server B, which has lower load at that moment. This ensures that the user’s session remains responsive and unaffected by server load fluctuations.
Thank you.
