Here are the main load balancer models, including their descriptions, advantages and disadvantages: 1. **Round Robin**: - **Description**: Distributes requests sequentially among available servers. - **Benefits**: Simple to implement and understand. - **Disadvantages**: Does not consider the current server load, which can lead to imbalances. 2. **Least Connections**: - **Description**: Directs the request to the server with the lowest number of active connections. - **Benefits**: Helps balance load more equitably. - **Disadvantages**: May not be effective in scenarios with long-lasting connections. 3. **IP Hash**: - **Description**: Uses the client's IP address to determine which server will fulfill the request. - **Benefits**: Ensures that requests from the same client are sent to the same server. - **Disadvantages**: May lead to uneven load distribution. 4. **Weighted Round Robin**: - **Description**: Assigns weights to servers, distributing more requests to the most capable servers. - **Benefits**: Flexible and allows optimization based on server capabilities. - **Disadvantages**: Complexity in setting up and maintaining weights. 5. **Least Response Time**: - **Description**: Directs the request to the server with the shortest response time. - **Benefits**: Improves user experience by reducing response times. - **Disadvantages**: Requires continuous monitoring and may introduce overhead. 6. **Geographic**: - **Description**: Directs the request to the server geographically closest to the client. - **Benefits**: Reduces network latency and improves user experience. - **Disadvantages**: May be affected by changes in network topology. 7. **Sticky Sessions**: - **Description**: Maintains the client's connection to the same server throughout the session. - **Benefits**: Essential for applications that require
