This is a legacy API which has been hidden and will no longer be updated. We recommend using the new Auto Scaling API 3.0 which is standardized and faster.
Welcome to use Tencent Cloud Auto Scaling (AS)!
Auto Scaling (AS) can automatically adjust computing resources according to users' business needs and policies. AS can properly increase or decrease CVM instances and complete the configuration based on the scheduled, periodic or monitoring policies specified by users. It can automatically increase CVM instances to ensure smooth and healthy business operations when business demands are soaring, and reduce CVM instances to save resources and costs when business demands are decreasing.
Users can perform such operations such as managing scaling groups and setting scaling configurations. For information on supported operations, please refer to API Overview.
Before using these APIs, please make sure that you have a thorough understanding of AS Product Overview and calling methods.
