AGENDA
• Configuration Management as a concept
• Infrastructure as code
• Rich tooling nature for *nix platforms
• PowerShell as the configuration tool
• Puppet and PowerShell
MANUAL CONFIG CHANGES
• People are rubbish!• Cut corners• Make mistakes• Techniques differ from person to person
• amount of work = Work hours * Number of operations staff
AUTOMATED CONFIG CHANGES
• Machines are reliable in what they do!
• amount of work = Number of machines * 24
TERMINOLOGY
• What do I mean by infrastructure?
• webserver
• databases
• load balancers
• firewalls
• Code
• Anything that is written and executed to do a job
INFRASTRUCTURE AS CODE
• SysAdmin writes ssh loop in bash – EUREKA!
• Other SysAdmins love it and add more “code” to it
• No tests, code is brittle.
SUMMARY
• Infrastructure as Code is a much better way of interacting with our systems
• Great tooling to help us do this
• PowerShell is a windows automation framework that keeps getting better
• Puppet and PowerShell work excellently together
• Windows server management should no longer be tough
