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
```

Adding trusted root certificates to the server

Mac OS X

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ~/new-root-certificate.crt
sudo security delete-certificate -c "<name of existing certificate>"

Windows

certutil -addstore -f "ROOT" new-root-certificate.crt

	# 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.
