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 sale 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 offers multiple instance types based on their CPU and memory specifications. 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 applications 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 corresponds to a hyperthread of an Intel® Xeon® 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 instance type selection.

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

Note
  • 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 is based on the 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. Changes to the host of an instance of this instance family may cause failures to decrypt data. Proceed with caution.
  • By default, auto failover is disabled. You can enable it. For more information, see Modify instance maintenance attributes. Auto failover causes the host of an instance to change. Changes to the host of an instance of this instance family may cause failures to decrypt data. 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 security-enhanced instances.
  • You can go to the ECS Instance Types Available for Each Region page to view the instance types available in each region.

  • Intel SGX is based on the 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. Changes to the host of an instance of this instance family may cause failures to decrypt data. Proceed with caution.
  • By default, auto failover is disabled. You can enable it. For more information, see Modify instance maintenance attributes. Auto failover causes the host of an instance to change. Changes to the host of an instance of this instance family may cause failures to decrypt data. 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 security-enhanced instances.

r5, memory-optimized instance family

Features:
  • Compute:
    • Offers a CPU-to-memory ratio of 1:8.
    • Uses 2.5 GHz Intel® Xeon® Platinum 8163 (Skylake) or Intel® Xeon® Platinum 8269CY (Cascade Lake) processors for consistent computing performance.
      Note Instances of this instance family may be deployed on different server platforms. If your business requires all instances to be deployed on the same server platform, we recommend that you use the r6, r6e, or r7 instance family instead.
  • Storage:
    • Is an instance family in which all instances are I/O optimized.
    • Supports ESSDs, standard SSDs, and ultra disks.
      Note The maximum performance of disks varies based on instance families. A single instance of this instance family can deliver up to 200,000 IOPS. For higher storage I/O performance, we recommend that you use g6se.
  • Network:
    • Supports IPv6.
    • Provides ultra-high packet forwarding rates.
    • Provides high network performance based on large computing capacity.
  • Applicable scenarios:
    • Scenarios where large volumes of packets are received and transmitted, such as on-screen video comments and telecom data forwarding
    • High-performance databases and in-memory databases
    • Data analysis, data mining, and distributed memory caching
    • Enterprise-level memory-intensive applications such as Hadoop clusters and Spark clusters

d2c, compute-intensive big data instance family

Features
  • Is equipped with high-capacity and high-throughput local SATA HDDs and provides a maximum bandwidth of 35 Gbit/s among instances.
  • Supports online replacement and hot swapping of damaged disks to avoid instance shutdown.
    If a local disk fails, you will receive a notification about the system event. You can respond to the system event by initiating the process of fixing the damaged disk. For more information, see Overview of system events on ECS instances equipped with local disks.
    Notice After you initiate the process of fixing the damaged disk, data in the damaged disk cannot be recovered.
  • Compute:

    • Supports enhanced SSDs (ESSDs), standard SSDs, and ultra disks.
  • Network:
    • Supports IPv6.
    • Provides high network performance based on large computing capacity.
  • Applicable scenarios:
    • Big data computing and storage business scenarios in which services such as Hadoop MapReduce, HDFS, Hive, and HBase are used
