# Automated AMI and Snapshot Deletion
#
# @author Bobby Kozora
#
# This script will search for all instances having a tag named "Backup" with a value of "Backup".
# As soon as we have the instances list, we loop through each instance
# and reference the AMIs of that instance. We check that the latest daily backup
# succeeded then we store every image that's reached its DeleteOn tag's date for
# deletion. We then loop through the AMIs, deregister them and remove all the
# snapshots associated with that AMI.

NGINX Performance Tuning

Content Compressions and Decompression

• Documentation
  • NGINX http_gzip module
  • NGINX http_gunzip module
• Enable gzip. by default, we’re not going to compress the responses that we’re getting from proxied servers or any piece of content that isn’t HTML.
• But if one of our proxied servers happens to send us a pre-compressed response then we probably want to decompress it for clients that can’t handle gzip. In this situation, we’ll use the gunzip module

  $ vim /etc/nginx/nginx.conf
