AWS is expanding the Extras catalog in HAQM Linux 2 to include AWS-optimized variants of new Linux Kernel releases. Starting today, an AWS-optimized Linux Kernel 4.19 is now available in HAQM Linux 2 in the Extras channel. The new kernel includes enhancements such as improved performance on A1 instances and higher bandwidth with lower latency on smaller instance types. The Linux Kernel 4.14 continues to be available as the pre-installed and default kernel in HAQM Linux 2 and receives long-term support.
Extras in HAQM Linux 2 provide access to bleeding-edge software such new versions of language runtimes, toolchains, databases, and web stacks on a stable long-term supported Operating System (OS) to alleviate the compromise between OS stability and software freshness. Going forward, AWS will make additional kernels available via Extras.
You can install and use the 4.19 Kernel by running sudo amazon-linux-extras install kernel-ng and rebooting your instance. Feedback on HAQM Linux 2 can be provided through your designated AWS representative or the HAQM Linux Discussion Forum.
