12. LIFE WOULD BE AMAZING IF WE ONLY HAD TO WORRY ABOUT BUSINESS LOGIC
13. BUT
14. WE HAVE TO CARE ABOUT SERVERS bugs in production! version mismatches! kernel issues! hardware failures! security holes! architecture mismatches! missing hardware instructions! virtualization bugs! performance drops! server bills! client latency! bandwidth costs! internet!!1! omg hakx!
15. how do we make servers look like code?
17. full-featured Turing-complete very well supported
18. class nginx { package { 'nginx': ensure => latest } service { 'nginx': ensure => running } file { '/etc/nginx/nginx.conf': ensure => present, source => 'puppet:///modules/nginx/nginx.conf', notify => Service['nginx'], } }
