Auto Scaling Service – Pricing Overview
The Auto Scaling service itself is free of charge. You do not incur any additional costs for using Auto Scaling to automatically manage the number of computing instances based on demand. This means that setting up scaling groups, configuring scaling policies, and using the Auto Scaling interface or APIs will not result in extra charges.
However, it is important to note that while Auto Scaling as a feature or management tool is free, the underlying resources it controls are not. You will be billed for any services that Auto Scaling creates, removes, or manages on your behalf. These associated services typically include:
CVM Instances (Cloud Virtual Machines)
- When Auto Scaling automatically launches new CVM instances to handle increased traffic or workloads, you will be charged for those instances at the standard rates.
- This includes charges based on the instance type, CPU, memory, storage (system and data disks), bandwidth, and any other attached resources.
- If you manually add CVM instances to an Auto Scaling group, those too will continue to accrue regular charges.
Storage Services
- If your CVM instances use cloud storage (e.g., Cloud Block Storage, SSDs, HDDs), these will incur separate storage costs.
- Auto Scaling does not manage storage directly, but instances it provisions may have associated disks, which are billable.
Load Balancers
- Auto Scaling is often used in conjunction with Load Balancers (such as CLB or ELB) to distribute traffic across scaled instances.
- The use of load balancers incurs charges based on usage, data transfer, and number of connections.
Network and Bandwidth
- Internet or internal traffic generated by scaled instances will be billed based on your configured bandwidth package or pay-as-you-go model.
- Auto Scaling doesn't add extra fees for network configuration, but scaled instances using bandwidth will still be charged.
