Alibaba Cloud Auto Scaling provides the following functions:
Scales up ECS instances horizontally according to your business needs by automatically adding or removing ECS instances.
Supports Sever Load Balancer configuration. When ECS instances are added or removed, Auto Scaling also adds or removes corresponding ECS instances from Sever Load Balancer instances.
Supports the RDS access whitelist. When ECS instances are added or removed, Auto Scaling will also add or remove their IP addresses from the RDS access whitelist.
On demand: Allocates resources to where they are needed, removing a user’s need to predict demand and minimizing the impact of traffic bursts.
Automated: Automatically creates and releases ECS instances based on templates. Configures access whitelists for the Server Load Balancer and RDS services.
Rich: Allows configuration of multiple scaling modes simultaneously, such as timing, dynamic, custom, fixed, and healthy modes. External monitoring systems can be accessed through APIs.
Smart: Suits various complicated scenarios through smart scheduling.
Video production and hosting: Auto Scaling allows video companies to automatically scale their resources to handle rising demands for popular events and programs.
Video streaming: Companies that cannot predict their business loads can use Auto Scaling to automatically scale their resources based on CPU usage, loads, or bandwidth usage.
Gaming: Auto Scaling can regularly scale up the system at pre-defined intervals. For example, scaling can be started at 12:00 AM and again from 6:00 PM to 9:00 PM, in order to effectively manage peak traffic intervals.
