Auto Scaling
Auto Scaling automatically adjusts the number of KEC instances used by your business based on the scaling policies that you set. Auto Scaling helps ensure that you have the correct number of KEC instances to meet your changing business needs.
Benefits
Automated Deployment
Auto Scaling automatically adds or removes KEC instances, with no manual intervention required.
Cost-Effectiveness
Auto Scaling helps you use the most appropriate number of KEC instances to meet the requirements of a specific business scenario.
High Availability
Auto Scaling monitors the health of KEC instances and automatically replaces unhealthy ones with new instances.
Flexible Configuration
Auto Scaling allows you to flexibly specify launch configurations and scaling policies based on your business needs.
Features
Automatic Scaling
Auto Scaling automatically adjusts KEC instances to ensure healthy business running.
Automatic Notification
Auto Scaling notifies you of changes in a scaling group in a timely manner.
Scheduled Scaling
Auto Scaling allows you to schedule scaling based on usual traffic changes to properly use KEC instances.
Custom Configuration
Auto Scaling supports different types of KEC instances to meet the requirements of different business scales and scenarios.
Scenarios
Scenarios
The requests from clients are forwarded to KEC instances by SLB. When the traffic changes rapidly, Auto Scaling automatically scales in or out KEC instances to cope with the changes.
Configure a Scheduled Task in Advance
If the time when KEC instances need to be scaled in or scaled out is determined, you can create a scheduled task in Auto Scaling. When the specified time arrives, Auto Scaling automatically adds or removes KEC instances.
Address Business Surges at Low Cost
To cope with a business surge, more KEC instances need to be deployed in advance to prevent the existing KEC instances from being overloaded due to the increase of CPU usage. When the business load decreases, KEC instances need to be removed based on the actual load. With Auto Scaling, you only need to create an alarm-triggered policy in advance. Auto Scaling then automatically determines whether a scale-in or scale-out is required based on the metric that you set. When the value of the specified metric reaches the threshold, Auto Scaling automatically adds or removes KEC instances in real time. This not only saves costs but also frees you from manual scaling operations.
Automatically Replace Unhealthy KEC Instances
To prevent unhealthy KEC instances from affecting your business, you must always take note of the running status of KEC instances and be prepared to resolve issues at any time. Auto Scaling can periodically check the health of KEC instances. When an unhealthy KEC instance is detected, Auto Scaling automatically launches a new KEC instance to replace the unhealthy one. You can check the operation records in scaling activity logs.
