Elastic Compute Service:Overview of ECS instance families

Last Updated:Sep 30, 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 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

    • Enterprise-level instances belong to a series of instance families that Alibaba Cloud introduced in September 2016. Enterprise-level instance families provide high performance, consistent computing power, and balanced network performance. Enterprise-level instance families have exclusive and consistent computing, storage, and network resources, and are suitable for enterprise scenarios that require high business stability.

    • Entry-level instance families are a series of instance families intended for small and medium-sized websites or individual developers. Entry-level instances share resources, in contrast with enterprise-level instances that each have their own exclusive resources. As a result, entry-level instances do not provide consistent computing performance, but cost less.

    • ECS Bare Metal Instance families combine the strengths of both physical machines and ECS instances to deliver powerful and robust computing capabilities. Using virtualization 2.0, ECS Bare Metal Instance provides your business applications with direct access to the processor and memory resources of the underlying servers without virtualization overheads. ECS Bare Metal Instance retains the hardware feature sets such as Intel VT-x and resource isolation capabilities of physical machines, which is ideal for applications that need to run in non-virtualization environments on the cloud.

    • High-performance computing instance families allow you to aggregate and scale computing capabilities and perform parallel computation to solve major challenges across multiple fields, including science, engineering, and commerce.

    • Heterogeneous computing refers to computing performed by a system that contains computational units that use different instruction sets and architectures. In heterogeneous computing instance families, dedicated hardware is used in scenarios for which the hardware is best suited. In specific scenarios, heterogeneous computing instance families can outperform non-heterogeneous computing instance families by one or more orders of magnitude.

  • Naming conventions for instance types

    Each instance family name is in the ecs.<Instance family> format. Each instance type name is in the ecs.<Instance family>.<nx>large format.

    • ecs: is the product code of ECS.

    • <Instance family>: consists of an instance family name body and an instance family name suffix.

      Note

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.

  • CPU base frequency: also known as core frequency, refers to the standard rate at which a processor is running without overclocking or special optimization. The CPU base frequency is the operating speed specified by the designer of a processor and is the typical clock speed at which the processor reliably runs under typical workloads.

  • CPU turbo frequency: refers to the maximum clock frequency that the core frequency of a processor can temporarily achieve.

Memory

  • Memory: stores and retrieves data that can be quickly accessed on an ECS instance. Memory temporarily stores data generated when the ECS instance is running programs and processing data. If the ECS instance is shut down or restarted, the data stored in memory is lost.

  • Persistent memory: provides a lower access rate compared with regular memory. When an ECS instance is stopped or restarted, data in persistent memory is retained.

  • Encrypted memory: uses encryption techniques to protect data in 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

  • Network baseline bandwidth: refers to the maximum amount of data that can be transmitted over a network connection in a specific period of time, which is the initial bandwidth setting for a network connection. You can select network baseline bandwidths based on your business requirements. For more information, see Network bandwidth.

  • Network burst bandwidth: is supported by specific instance types that belong to sixth-generation or later instance families. 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 traffic spikes. After the network burst credits are exhausted, the network bandwidth drops back to the baseline level. Network burst bandwidth is a way to utilize idle resources. No service level agreement (SLA) commitments are made for network burst bandwidth. For more information, see the Burst bandwidth section of the "Network bandwidth" topic.

  • Full-duplex network bandwidth: is supported by instance types that belong to seventh-generation or later instance families. Based on the full-duplex network bandwidth, the inbound and outbound bandwidths can reach the preset bandwidth values, without affecting each other. For more information, see the corresponding performance metrics in each instance family of this topic. An instance can send and receive packets at full rates. For more information, see the Internal bandwidth section of the "Network bandwidth" topic.

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 baseline bandwidth: is the maximum disk bandwidth that an instance type can consistently support for disks in compliance with an SLA commitment.

  • Disk burst bandwidth: is the disk bandwidth to which an instance type can burst. Disk burst bandwidths are time-limited and dependent on the number of disk bandwidth resources that an instance provides. No SLA commitments are made for disk burst bandwidths.

Disk IOPS

  • Baseline IOPS: is the maximum IOPS that an instance type can consistently support for cloud disks in compliance with an SLA commitment.

  • Burst IOPS: is the IOPS to which an instance type can burst. Burst IOPS is time-limited and dependent on the number of I/O resources that an instance provides. No SLA commitments are made for burst IOPS.

Burst performance

  • Average baseline CPU performance: The amount of CPU capacity that is continuously provisioned to a burstable instance.

  • CPU credits per hour: When a burstable instance starts, it begins to consume CPU credits to maintain its computing performance. The instance earns CPU credits at a specific rate that varies based on the instance type. The number of CPU credits that a vCPU can earn per hour varies based on the instance type. The CPU credits per hour column in the instance type table indicates the CPU credits that all vCPUs of a burstable instance can earn per hour.

  • Maximum CPU credit balance: The maximum number of CPU credits that a burstable instance can earn within a 24-hour period. The CPU credit balance is valid for up to 24 hours. Each burstable instance earns CPU credits at a specific rate based on the instance type and can accrue only a limited number of credits in the CPU credit balance.

g7t, security-enhanced general-purpose instance family

Features:

  • This instance family supports up to 256 GiB of encrypted memory and confidential computing based on Intel® Software Guard Extensions (SGX) to protect the confidentiality and integrity of essential code and data from malware attacks.

  • This instance family supports Virtual SGX (vSGX) and allows you to select instance types based on your business requirements.

    Important

    If you use keys (such as SGX sealing keys) that are bound to hardware to encrypt the data of an instance within an Intel SGX enclave, the encrypted data cannot be decrypted after the host of the instance is changed. We recommend that you perform data redundancy and backup at the application layer to ensure application reliability.

  • This instance family implements trusted boot based on TCM or TPM chips. During a trusted boot, all modules in the boot chain from the underlying server to the guest operating system are measured and verified.

  • 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.

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.

    Note

    For more information, see Configure the usage mode of persistent memory.

  • This instance family provides the ecs.re6p-redis.<nx>large instance types for Redis applications.

    Note

    ecs.re6p-redis.<nx>large instance types are exclusively provided for Redis applications. Persistent memory on instances of these instance types is used as memory by default and cannot be re-configured as local SSDs. For information about how to deploy a Redis application, see Deploy Redis on persistent memory-optimized instances.
