An Elastic Compute Service (ECS) instance is the smallest unit that can provide compute capabilities and services for your business. Compute capabilities vary based on instance types. This topic describes available ECS instance families, including their features, specifications, and application scenarios.

ECS instances are categorized into different instance families based on their usage scenarios. Each instance family is divided into different instance types based on their CPU and memory specifications. ECS instance type defines the basic properties of an ECS instance, such as CPU, 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 have high requirements for business stability. Alibaba Cloud ECS instance families are divided 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. Each vCPU in an enterprise-level instance family corresponds to a hyperthread of the 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 an instance family or across 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 divided into the following categories based on the system architecture and usage scenarios.

Enterprise-level computing instance families based on the x86 architecture
Recommended intance families Other available instance families
Enterprise-level heterogeneous computing instance families

d2s, storage intensive big data instance family

Features
  • Is an instance family in which all instances are I/O optimized.
  • Supports ESSDs, standard SSDs, and ultra disks.
  • Is attached with high-capacity local SATA HDDs that have high throughput and has a maximum of 35 Gbit/s bandwidth 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 to fix the damaged disk. For more information, see Overview of system events on ECS instances equipped with local disks.
    • If a backup disk is available on the physical machine, Alibaba Cloud will replace the damaged disk with the backup disk online.
    • If no backup disks are available on the physical machine, the disk hardware must be replaced manually before Alibaba Cloud can replace the damaged disk.
    Notice After you start the process to fix the damaged disk, data in the damaged disk cannot be recovered.
  • Uses 2.5 GHz Intel ® Xeon ® Platinum 8163 (Skylake) processors.
