      What is Elastic Compute Service (ECS)?

      Elastic Compute Service (ECS) is a high-performance, stable, reliable, and scalable IaaS-level service provided by Alibaba Cloud. It is more convenient and efficient compared with physical servers. You can immediately acquire ECS instances and scale computing resources on-demand. ECS provides a variety of instance types that suit various business needs and help boost business growth.

      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.

      How are enhanced SSDs billed?

      Enhanced SSDs support both subscription and pay-as-you-go billing methods. For more information, visit the Pricing page.

      How is the public network usage of ECS instances billed?

      For details, see Billing of Internet bandwidth.

      For more information, see Pricing FAQ.

      What are enterprise-level instances? What are entry-level instances?

      Enterprise-level instances are a series of instance families released by Alibaba Cloud in September 2016. Enterprise-level instances feature high performance, consistent computing power, and balanced network performance. These instances have exclusive and consistent computing, storage, and netw
