An Elastic Compute Service (ECS) instance is a virtual server and the smallest computing service unit in the cloud. An instance type essentially determines the hardware of the host computer used for your instance. Each instance type offers different compute and memory capabilities. This topic describes all ECS instance families available for purchase and introduces their features, specifications, and use scenarios to facilitate instance type selection.
Introduction
ECS provides a variety of instance families for different use scenarios or application workloads. Each instance family consists of multiple instance types that each have a combination of different capacities, including CPU and memory capacities. The ECS instance type defines the basic properties of an ECS instance, including CPU (CPU model and clock speed) and memory. In addition to the instance type, you must configure the Elastic Block Storage (EBS) devices, image, and network type when you create an ECS instance.
Categories of instance families:
Enterprise-level instance families, entry-level instance families, ECS Bare Metal Instance families, high-performance computing instance families, and heterogeneous computing instance families
Naming conventions for instance types
Instance type specifications
Specification | Description |
vCPU | Enterprise-level instance families offer consistent performance and dedicated resources. In enterprise-level instance families, each vCPU of x86-based instance types corresponds to a hyperthread of a processor core, whereas each vCPU of Arm-based instance types corresponds to a physical processor core. |
Processor | The physical CPU model of an ECS instance. The performance of the processor varies based on the processor type.
|
Memory |
|
vTPM | Trusted computing capabilities: Trusted Platform Modules (TPMs) or Trusted Cryptography Modules (TCMs) serve as trusted computing bases (TCBs) on the underlying physical servers that host trusted instances to ensure the tamper-protected, trusted boot of the instances. In addition, virtual TPM (vTPM) can be used to measure the critical components of the boot chain of instances. |
Local storage | Local storage, also called local disks or cache disks, refers to the disks that are attached to the physical servers on which ECS instances are hosted. Local storage provides temporary block storage for ECS instances. Local storage capacity is measured in GiB. When the computing resources (vCPUs and memory) of an instance are released or when an instance is failed over, data that is stored on the local disks of the instance may be lost. For more information, see Local disks. |
Network bandwidth |
Note Instance type specifications are all verified and obtained within a pure forwarding test environment. In actual business scenarios, the performance of an instance may vary based on other factors such as instance workload type, packet size, connection type (persistent or short-lived), image version, and networking model. We recommend that you perform business stress tests on instances to select appropriate instance types. |
Packet forwarding rate (pps) | The sum of maximum inbound and outbound packet forwarding rates. For information about how to test the packet forwarding rate of an instance, see Test the network performance of an instance. Note Instance type specifications are all verified and obtained within a pure forwarding test environment. In actual business scenarios, the performance of an instance may vary based on other factors such as instance workload type, packet size, connection type (persistent or short-lived), image version, and networking model. We recommend that you perform business stress tests on instances to select appropriate instance types. |
Connections | A connection, also called a session, is the process of connecting a client to a server and transferring data between them. A connection is uniquely defined by the network communication quintuple that consists of a source IP address, a destination IP address, a source port, a destination port, and a protocol. The connections of an ECS instance include TCP, UDP, and Internet Control Message Protocol (ICMP) connections. If your business is sensitive to concurrent network connections, select an instance of an instance type of which the maximum number of connections meets your business requirements. |
NIC multi-queue | The network interface controller (NIC) multi-queue feature allows instance types to support multiple traffic queues on each elastic network interface (ENI). The number of NIC queues represents the maximum number of queues that an instance type supports per ENI. Performance bottlenecks may occur when you use a single vCPU to process NIC interrupts on an ECS instance. To improve network performance, you can use the NIC multi-queue feature to distribute NIC interrupts across different vCPUs. |
ENI | ENIs are virtual network interfaces that provide network connectivity and IP addresses for ECS instances that are deployed in virtual private clouds (VPCs). You can bind one or more ENIs to each ECS instance. You can bind secondary ENIs to or unbind secondary ENIs from different ECS instances to allow for more flexibility and scalability in network configurations and meet network requirements in different scenarios. For example, you can use ENIs to create multi-IP address, multi-NIC, or high-availability networks. |
ERIs | Elastic RDMA Interfaces (ERIs) are virtual network interfaces that can be bound to ECS instances. ERIs must depend on ENIs to enable RDMA devices. An ERI reuses the network to which an ENI belongs. This allows you to use the RDMA feature in the original network and enjoy the low latency provided by RDMA without the need to modify service networking. |
Network cards | The maximum number of network cards that are supported by an ECS instance. You can call the DescribeInstanceTypes operation to query the number of network cards supported by each instance type. |
Disk bandwidth |

Disk IOPS |
|
Burst performance |

Intel Ice Lake supports only remote attestation based on Intel Software Guard Extensions Data Center Attestation Primitives (Intel SGX DCAP) and does not support remote attestation based on Intel Enhanced Privacy ID (EPID). You must adapt applications before you can use the remote attestation feature. For more information about remote attestation, see Strengthen Enclave Trust with Attestation.
Intel SGX depends on host hardware. This instance family does not support hot migration.
Operations, such as changing instance types and enabling the economical mode, may cause the host of an instance to change. For instances of this instance family, the host change may cause data decryption to fail. Proceed with caution.
By default, failover is disabled. You can enable failover. For more information, see Modify instance maintenance attributes. Failover causes the host of an instance to change. For instances of this instance family, the host change may cause data decryption to fail. Proceed with caution.
When you create a security-enhanced instance, you must select a dedicated image to use the security features. For more information, see Create a trusted instance.

You can go to the Instance Types Available for Each Region page to view the instance types available in each region.
For more information about these specifications, see the "Instance type specifications" section in Overview of instance families. Packet forwarding rates vary significantly based on business scenarios. We recommend that you perform business stress tests on instances to choose appropriate instance types.
The results for network capabilities are the maximum values obtained from single-item tests. For example, when network bandwidth is tested, no stress tests are performed on the packet forwarding rate or other network metrics.
