What is load balancing?
Typical data centers receive millions of requests per second. To handle this volume, thousands of servers work together to share the load. A load balancer (LB) distributes incoming client requests across a pool of available servers. Its primary job is to divide traffic fairly to prevent any single server from crashing due to overload.
Note: Here, it’s important to consider how incoming requests will be distributed across all available servers.
Why do we need load balancers?
The load balancer is the first point of contact inside a data center after the firewall. While low-traffic services may not require one, load balancers provide critical capabilities as traffic increases:
Scalability: You can add servers to increase capacity seamlessly. Load balancers make upscaling or downscaling transparent to ...
