This topic describes available ECS instance families and their features, specifications, and application scenarios.

An ECS instance is the smallest unit that can provide compute capabilities and services for your business.

ECS instances are categorized into different instance families based on the business scenarios to which they can be applied. Each instance family is divided into different instance types based on their CPU and memory specifications. The ECS instance type defines the basic properties of an ECS instance: CPU (including CPU model and clock speed) and memory. When you create an instance, you must also configure the block storage, image, and network type in addition to the instance type.
Note The available instance families and types vary with region. You can go to the ECS Instance Types Available for Each Region page to view the instance types available in a region.
Enterprise scenarios have high requirements for business stability. Alibaba Cloud ECS instance families are divided into enterprise- and entry-level based on whether the instance families are suited for enterprise scenarios. Enterprise-level instance families offer consistent performance and dedicated resources. Each vCPU in enterprise-level instance families corresponds to an Intel ® Xeon ® core hyperthread.
Note For the differences between enterprise-level and entry-level instance families, see ECS instance FAQ.

You can upgrade or downgrade instances within or between certain instance families. For such instance families and the corresponding upgrade and downgrade rules, see Instance families that support instance type changes.

Some instance families are no longer available for purchase. For more information, see Phased-out instance types.

Alibaba Cloud ECS instances are categorized into the following instance families:

Instance specification metrics

Metric Description
Local storage Local storage, also called cache disks or local disks, refers to the disks attached to the physical servers where ECS instances are hosted. Local storage provides temporary block storage for instances. Local storage capacity is measured in GiB. Data stored in the local disks may be lost in some cases, such as when the compute resources (vCPU and memory) of an instance are released or an instance is migrated because the physical server is down. For more information, see Local disks.
Bandwidth The maximum bandwidth in one direction. Inbound bandwidth and outbound bandwidth are calculated separately.
Packet forwarding rate The maximum sum of inbound and outbound packet forwarding rates. For details about how to test the packet forwarding rate, see Test network performance.
NIC queues The maximum number of NIC queues that the primary NIC of an instance supports. If your instance type is not of an ECS Bare Metal Instance family, the maximum number of NIC queues supported by the secondary NIC is the same as that supported by the primary NIC.
ENIs Enterprise-level instance types that are equipped with two or more vCPUs support Elastic Network Interfaces (ENIs). Entry-level instance types that are equipped with four or more vCPUs support ENIs. For more information, see ENI overview.
