Enhanced Networking provides higher I/O performance and lower CPU utilization by using SR-IOV (Single Root I/O Virtualization). You enable it by selecting an instance type that supports it and ensuring the appropriate drivers are installed on the OS.

Check Support via CLI

Steps to Enable

1
Choose a supported instance type (e.g., C5, M5, R5).
2
Ensure the necessary drivers (ena or ixgbevf) are installed on the AMI.
3
For most modern AMIs, ENA (Elastic Network Adapter) is enabled by default.
4
Verify by checking the 'ENA Support' attribute on the instance.
