Use Auto Scaling to Automatically Adjust Web Resources

The following lab primarily uses Alibaba Cloud Auto Scaling. In this lab, a common website architecture is built, which consists of Server Load Balancer (SLB), ApsaraDB for RDS (RDS), ApsaraDB for Redis (Redis), and Elastic Compute Service (ECS). Among these components, SLB is used as the server load balancer, RDS is used as the database, Redis is used as the cache, and ECS is used as the web server. Auto Scaling scales the number of ECS instances based on service requests.
