operations staff
AUTOMATED CONFIG CHANGES

TERMINOLOGY
• What do I mean by infrastructure?

databases
•
load balancers
•
firewalls
• Code
• Anything that is written and executed to do a job
INFRASTRUCTURE AS CODE

EUREKA!
• Other SysAdmins love it and add more
“code” to it
• No tests, code is brittle.
CODE IS BETTER!
