Description: Session Persistence of the Elastic Load Balancer is a fundamental feature that allows the load balancer to link a user’s session to a specific target, such as a server in a group of instances. This means that once a user starts a session and is directed to a particular server, all subsequent requests from that user will be sent to the same server for the duration of the session. This functionality is crucial for applications that require session state, such as those handling shopping carts or temporary user data. Without session persistence, a load balancer could direct a user’s requests to different servers, which could result in an inconsistent user experience and data loss. Persistence can be implemented in various ways, including cookies, IP addresses, or using session identifiers. This feature not only enhances the user experience but also optimizes system performance by reducing the load on servers, as it minimizes re-authentication requests and maintains continuity in data handling. In summary, Session Persistence is essential to ensure that web applications operate smoothly and efficiently, providing a more coherent and satisfying user experience.
