Use Case Scenarios of Session Persistence in Load Balancer
Session persistence in load balancer setups is crucial for various use case scenarios in system design, ensuring seamless user experiences, efficient resource utilization, and enhanced application reliability. Here are some common use case scenarios:
- E-commerce Websites:
- In an e-commerce website, maintaining session persistence ensures that users’ shopping carts remain consistent across multiple requests and interactions.
- When a user adds items to their cart, updates quantities, or proceeds to checkout, session persistence ensures that their session remains tied to the same backend server, preventing cart items from being lost or reset during the shopping session.
- Online Banking and Financial Services:
- For online banking applications, session persistence is critical for maintaining secure and uninterrupted user sessions.
- Session affinity ensures that users remain connected to the same server during their banking session, preserving authentication status, transaction history, and sensitive account information.
- This helps prevent unauthorized access and enhances the overall security of the banking application.
- Gaming Platforms:
- In multiplayer online gaming platforms, session persistence ensures that players remain connected to the same game server throughout their gaming session.
- This enables continuity in gameplay, preserves player progress, and maintains synchronization of game state across multiple players.
- Session persistence also facilitates features like in-game chat, player inventory management, and leaderboard tracking.
- Collaborative Software and Productivity Tools:
- Collaborative software applications, such as project management tools or document editing platforms, rely on session persistence to maintain user sessions and document states.
- Session affinity ensures that team members collaborating on the same project or document are routed to the same server, allowing real-time updates, concurrent editing, and seamless collaboration without data conflicts or version inconsistencies.
Load Balancer Session Persistence
Load Balancer Session Persistence explores how load balancers manage user sessions in web applications. It explains how these systems evenly distribute incoming traffic across multiple servers to maintain stability and prevent overload. The article will help to understand the concept of session persistence, where load balancers ensure that a user’s requests consistently reach the same server during a session.
