Elastic Compute Service:ECS instance families

Last Updated:Mar 06, 2024

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.

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. 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 also configure the Elastic Block Storage (EBS) devices, image, and network type when you create an ECS instance.

Note

The available instance families and types vary based on regions. You can go to the ECS Instance Types Available for Each Region page to view the available instance types in each region.

Enterprise scenarios require high business stability. Alibaba Cloud ECS instance families are categorized into enterprise-level and shared instance families based on whether the instance families are suitable for enterprise scenarios. 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. For more information about the differences between enterprise-level and shared instance families, see Instance FAQ.

You can upgrade or downgrade instance types within the same instance family or across different instance families. For more information, see Instance families that support instance type changes.

For information about how to choose instance families based on scenarios, see Best practices for selecting instance types.

ECS instance families are categorized into the following categories based on their system architecture and use scenarios.

re6p, persistent memory-optimized instance family

For answers to commonly asked questions about persistent memory-optimized instances, see Instance FAQ.

Features:

  • This instance family uses Intel® OptaneTM persistent memory.

    Important

    The reliability of data stored in persistent memory depends on the reliability of persistent memory devices and the physical servers to which these devices are attached. This increases the risks of single points of failure (SPOFs). To ensure the reliability of application data, we recommend that you implement data redundancy at the application layer and use cloud disks for long-term data storage.

  • This instance family allows persistent memory to be used as memory or as local SSDs on instances of some instance types.

Instance type specifications

Specification

Description

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 baseline bandwidth

A network baseline bandwidth is the initial bandwidth that is allocated to a connection and represents the maximum transfer rate of the connection in normal cases. You can select network baseline bandwidths based on your business requirements. For more information, see Network bandwidth.

Network burst bandwidth

Specific instance types that belong to sixth-generation or later instance families support network burst bandwidths. When an instance has network burst credits, the instance can spend the credits to burst its network bandwidth beyond the baseline level. This allows you to obtain a higher transmission rate to handle burst peak traffic if your business traffic spikes. After the network burst credits are exhausted, the network bandwidth drop back to the baseline level. For more information, see the Burst bandwidth section in the "Network bandwidth" topic.

Packet forwarding rate (pps)

The sum of inbound and outbound packet forwarding rates. For information about how to test the packet forwarding rate of an instance, see Best practices for testing network performance.

Note

Instance type specifications are all verified and obtained within a test environment. In actual scenarios, the performance of an instance may vary based on other factors such as instance load, 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 with 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.

NIC queues

The maximum number of network interface controller (NIC) queues that are supported by the primary NIC of an instance. For the instance types other than ECS Bare Metal Instance types, the maximum number of NIC queues that are supported by a secondary NIC is the same as the maximum number of NIC queues that are supported by the primary NIC.

ENIs

The number of elastic network interfaces (ENIs) per instance, including one primary ENI.

Network cards

The total 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.
