Elastic Compute Service:retired ECS instance types

Last Updated:Mar 07, 2024

This topic describes all retired instance types on the China site (aliyun.com). However, the sn1, sn2, n1, n2, and e3 instance types are still available for purchase on the International site (alibabacloud.com).

Instance type changes

If you are using a retired instance type, we recommend that you change it to another instance type that is available for purchase. For information about the supported changes between instance types, see Instance families that support instance type changes.

Instance type specifications

Specification

Description

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 baseline bandwidth

A network baseline bandwidth is the initial bandwidth that is allocated to a connection and represents the maximum transfer rate of the connection in normal cases. You can select network baseline bandwidths based on your business requirements. For more information, see Network bandwidth.

Network burst bandwidth

Specific instance types that belong to sixth-generation or later instance families support network burst bandwidths. 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 burst peak traffic if your business traffic spikes. After the network burst credits are exhausted, the network bandwidth drop back to the baseline level. For more information, see the Burst bandwidth section in the "Network bandwidth" topic.

Packet forwarding rate (pps)

The sum of inbound and outbound packet forwarding rates. For information about how to test the packet forwarding rate of an instance, see Best practices for testing network performance.

Note

Instance type specifications are all verified and obtained within a test environment. In actual scenarios, the performance of an instance may vary based on other factors such as instance load, 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 with 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.

NIC queues

The maximum number of network interface controller (NIC) queues that are supported by the primary NIC of an instance. For the instance types other than ECS Bare Metal Instance types, the maximum number of NIC queues that are supported by a secondary NIC is the same as the maximum number of NIC queues that are supported by the primary NIC.

ENIs

The number of elastic network interfaces (ENIs) per instance, including one primary ENI.

Network cards

The total 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.
