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

ECS instances are categorized into multiple specification types, which are called type families, based on the business and scenarios. You may select various type families for one business scenario. Each type family contains multiple instance types with different CPU and memory specifications. ECS instance type includes the basic specifications of instances, including CPU model and clock speed. However, the attributes of a block storage, an image, and the network service of an ECS instance must also be defined simultaneously for the specific service type of the instance to be determined.
Note
The availability of instance type families and their types varies according to the regions and the amount of resources. Go to the purchase page to check the available instance types.

Alibaba Cloud ECS instances are categorized into the following type families according to business scenarios: enterprise-level instance type families and entry-level instance type families. Type families for enterprise-level computing feature stable performance and dedicated resources. For enterprise-level instances, each vCPU core is supported by one Intel Xeon CPU core through hyper-threading. For the differences, see Enterprise-level instances and entry-level instances FAQ.

Note
If you are using sn1, sn2, t1, s1, s2, s3, m1, m2, c1, c2, n1, n2, or e3, see Phased-out instance types.

Alibaba Cloud ECS instances are categorized into the following type families according to system structures and business scenarios:

* Cache disks, or Local disks, are the disks located on the physical servers (host machines) that ECS instances are hosted on. They provide temporary block level storage for instances.  In some cases, such as when the computing resources of an instance, including CPU and memory, are released, or an instance is in the downtime migration, data on the local disks is erased.  For more information, see Local disks.

** The maximum packet forwarding rate of inbound or outbound traffic. For more information about packet forwarding rate testing, see Test network performance.

*** The maximum number of NIC queues that an instance type supports.  If your instance is running CentOS 7.3, the maximum number of NIC queues is used by default.

**** An enterprise-level instance with 2 or more vCPU cores supports elastic network interfaces.  An entry-level instance with 4 or more vCPU cores supports elastic network interfaces.  For more information about elastic network interfaces, see Elastic network interfaces.
