Lots of Goodies
The AMI contains many new features, many of which were added in response to requests from our customers. Here’s a summary:
Kernel 4.9.51 – Based on the 4.9 stable kernel series, this kernel includes the ENA 1.3.0 driver along with support for TCP Bottleneck Bandwidth and RTT (BBR). Read my post, Elastic Network Adapter – High-Performance Network Interface for Amazon EC2 to learn more about ENA. Read the Release Notes to learn how to enable BBR.
Amazon SSM Agent – The Amazon SSM Agent is now installed by default. This means that you can now use EC2 Run Command to configure and run scripts on your instances with no further setup. To learn more, read Executing Commands Using Systems Manager Run Command or Manage Instances at Scale Without SSH Access Using EC2 Run Command.

OpenSSL – The AMI now uses OpenSSL 1.0.2k.
HTTP/2 – The HTTP/2 protocol is now supported by the AMI’s httpd24, nginx, and curl packages.
