Introduction
Alibaba Cloud Application Load Balancer (ALB) is a Layer 7 load balancing service that is designed to handle large-scale, modern web application traffic. It intelligently distributes incoming HTTP/HTTPS requests to multiple backend servers such as ECS instances or containers based on advanced and customizable routing rules. This enables high availability, scalability, and better fault tolerance for applications hosted on Alibaba Cloud.
