L4/L7 load balancers distribute traffic across multiple servers,
improving service stability, and automatic switchover on failure
delivers non-stop service.
All traffic hits one server, so a failure takes down the entire service
When traffic spikes from events or marketing, the server goes down
Server maintenance/updates require stopping the service, which is inconvenient
Distributes traffic to the best server using various algorithms such as Round Robin and Least Connection
Monitors server status in real time and automatically excludes failed servers
On server failure, immediately switches to healthy servers to guarantee non-stop service
Intelligently distributes traffic across multiple servers for stable service
