Definition: Load Balancing is the process of distributing network or application traffic across multiple servers to ensure optimal performance, reliability, and resource utilization.
Types of Load Balancing:
Round Robin: Distributes requests in a rotating sequence among available servers.
Least Connections: Sends traffic to the server with the fewest active connections.
Geographic Routing: Directs users to the nearest data center or region for faster response times.
.
Benefits for Systems:
Improved Performance: Avoids overloading a single server and enhances response times.
High Availability: Maintains system uptime by redirecting traffic from failed servers.
Scalability: Easily accommodates increased user load by adding more servers.
Common Use Cases:
Web Hosting Services: Keeps websites responsive even during high traffic periods.
Cloud Infrastructure: Balances resources across virtual machines or containers.
E-commerce Platforms: Ensures a smooth shopping experience during sales or peak times.
