This topic describes all phased-out instance types on the China site (aliyun.com). However, instance types sn1, sn2, n1, n2, and e3 are still available for purchase on the International site (alibabacloud.com).
Instructions for specifications
- The packet forwarding rate refers to the total number of inbound and outbound packets that can be processed by a network per second. For more information about how to test the packet forwarding rate, see Test network performance.
- NIC queues refer to the maximum number of NIC queues supported by the current instance type. By default, a CentOS 7.3 image uses the maximum number of NIC queues.
- Enterprise-level instance types that are equipped with two or more vCPUs support Elastic Network Interfaces (ENIs). Shared instance types that are equipped with four or more vCPUs support ENIs. For more information, see ENI overview.
Instance type upgrade
For information about the phased-out instance types that can be upgraded to new instance types, see Instance families supporting instance type changes.
