Tools Allowing Me to Sleep Better
1) nginx - a load balancer I have running on ec2 between running instances of osdir.com. If one goes down the others handle it all.
2) persistentFS - persistent storage for EC2 on S3 which operates exactly like a mounted filesystem. Rawk! for all you/we who don’t have access to AWS’s persistent storage for EC2 yet. Also soooooo beautiful for backups (which help me sleep better).
3) Large EC2 instances. They’re expensive, but the power, my god the power!
4) AWS’s firewalls. Let AWS block all the badboys (except ports you open).
5) XXXX Firewall. Not saying which, but it hooks up to iptables automagically.
6) Postfix. I killled sendmail on one of my servers the other day, installed postfix instead and watched the avg cpu load drop considerably.
