Auto Scaling (AS) provides you a highly efficient management policy for computing resources. You can set the time to execute management policy regularly or create a real-time monitoring policy to manage the number of CVM instances and deploy the environment for the instances, to ensure that your business runs smoothly. AS automatically increases the number of CVM instances during demand surges to maintain good performance and decreases the number during lulls to reduce costs.
AS automatically creates and removes CVM instances in a real time and dynamic way based on the business load, ensuring that you are running the optimal number of instances without manual intervention.
AS helps you maintain an optimal number of instances for variable business demands. When the demand rises, AS will automatically add new CVM instances rapidly, and when the demand drops, AS will automatically remove unnecessary instances accordingly. This improves device utilization and reduces the costs of deployment and instances.
AS allows you to set a schedule to plan the scaling activities to deal with regular changes in business load (e.g. scaling up at 21:00 every day).
AS automatically checks instances' health. Once AS detects a faulty instance, it will automatically create a healthy instance to replace the faulty one. This ensures that your application is getting the computing capacity as you expect so that your business can run normally and smoothly.
Easy to Audit
When using auto scaling, the user can record the trigger conditions, time, involved instances and success/failure reasons related to each scaling event. Visualized tracking, querying interfaces and SMS notifications are provided to help you locate root causes as soon as possible for prompt solution.
