Features that meet your needs in every scenario
Flexbile Puchasing Options
ECS provides flexible purchasing models such as subscription model, pay as you go, reserved instances, as well as preemptible instances to meet your different business needs.
You can make an Autoscaling group and your ECS instances in the group can automatically scale-out or scale-in according to the metrics or triggers or your choice such as CPU utilization or network utilization.
Auto Provisioning makes it easier for you to take advantage of preemptible instances. It will automatically pick the instances across instance families, availability zones and purchasing models according to your strategy such as 'lowest cost' and utilize preemptible instances as much as possible to maintain you ECS fleet at your desired capacity.
ECS allows you to turn off hyperthreading that is beneficial to certain workloads such as HPC. ECS also allows you to shut down certain amount of vCPUs in order to save licensing costs.
Dedicated Host Clusters
ECS provides Dedicated Host Clusters (DDH) so that the physical servers are dedicated to you without other tenants on it. You can place your virtual machines onto those servers according to your needs.

How to create an AccessKey?
Are fees still incurred after a pay-as-you-go ECS instance is stopped automatically due to an overdue payment or is manually stopped?
When the payment for a pay-as-you-go instance becomes overdue, the instance is automatically stopped and taken out of service.
You can stop a running pay-as-you-go instance in the ECS console or by calling the StopInstance operation. When the instance is stopped, its status changes to Stopped. Billing of pay-as-you-go instances in the Stopped state depends on their network types.
• VPC: The No Fees for Stopped Instances (VPC-Connected) feature takes effect on pay-as-you-go instances in VPCs. After the feature is enabled, pay-as-you-go instances in VPCs start being billed when they are created, stop being billed when they enter the Stopped state, and resume being billed when they are started again. With the feature enabled, the vCPUs, memory, and public IP addresses of a VPC-type ECS instance in the Stopped state will not incur any additional costs, but its data disks will continue to be billed. For more information, see No fees for stopped VPC instances.
• Classic network: ECS instances in classic networks will continue to be billed, even when they are in the Stopped state.
To which types of ECS instances is the No Fees for Stopped Instances (VPC-Connected) feature applicable?
The No Fees for Stopped Instances (VPC-Connected) feature is applicable to ECS instances that meet the following requirements:
• The network type of the instances is VPC.
• The instances use the pay-as-you-go billing method.
• The instances do not use local disks.
I have set Stop Mode to No Charges After Instance Is Stopped when stopping an instance. When I start this instance again, its public IP address changes. How do I keep the IP address from changing?
When an instance enters the No Fees for Stopped Instances state, its public IP address is released. When the instance is started again, it is assigned a new public IP address.
To retain the original public IP address of the instance, you can convert the IP address to an Elastic IP Address (EIP) before you stop the instance. For more information, see Convert an ECS public IP address in a VPC to an Elastic IP Address and ConvertNatPublicIpToEip.
Notice: After the IP address is converted to an EIP, you will be charged for the EIP while the instance is in the No Fees for Stopped Instances state. For more information, see Billing method of the EIP documentation.
Why has a pay-as-you-go bill been generated for my instance? What are the fees on the bill? You can copy your instance ID and perform the following steps to view the bill details:
1.Log on to the ECS console.
2.In the top navigation bar, choose Billing > User Center.
3.In the left-side navigation pane, choose Spending Summary > Instance Spending Detail.
4.Set the search criteria.
