Server Load Balancer


Overview

Manage sudden spikes in traffic, minimize response time and maintain 99.99% availability of your web application with Server Load Balancer. Server Load Balancer monitors the health of servers and ensures high availability by automatically distributing application requests to servers with optimal performance in different availability zones.

Alibaba Cloud Server Load Balancer is built to cope with high volume traffic and each year in November is put to the test during Alibaba’s annual Global Shopping Festival. Alibaba relies on Server Load Balancer to provide uninterrupted service during the festival by switching requests between data centers and transferring transactions to the most available server. This includes transferring requests to servers located over 1,000 kilometers away, without missing a single transaction.
