ECS comprises the following major components: instances, images, Block Storage devices, snapshots, security groups, and networks. For more information, see What is ECS?
|ECS instance||You are billed based on the instance type that you choose. The instance type determines

|Public bandwidth||An ECS instance can access the Internet through the following methods:
|Snapshot||Snapshots are billed based on the storage space usage.|
- Subscription: a billing method that allows you to pay for an instance upfront to use for the subscription period. The subscription billing method is suited for common services without traffic spikes, such as web services. For more information, see Subscription.
- Pay-as-you-go: a billing method that allows you to use an instance and pay afterwards for the resources it uses. The pay-as-you-go billing method is suited for scenarios with traffic spikes, such as temporary scaling, interim testing, and scientific computing. For more information, see Pay-as-you-go.
For more information about the difference between subscription and pay-as-you-go, see Comparison of billing methods.
Images can be used only along with ECS instances. Windows reserved instances can be used to offset image bills.
