Load Balancers in 1 diagram and 91 words
Explained as simply as possible… but not simpler.
A load balancer distributes network traffic across multiple servers so no single one gets overwhelmed.
It sits between clients and servers, rerouting traffic if a server fails to keep things running smoothly.
This helps ensure fast, reliable access to apps and services.
You need to know
Common ways to share traffic: round-robin, least connections, and IP hash.
Load balancers ping servers regularly to make sure they’re up before sending traffic.
They can be hardware devices, software, or cloud-based services.
