  • Requirements ❖ Fast project bootstrap ❖ Easy/fast environment creation ❖ On call for a different project ( @5 AM )
  • Solutions
  • High availability ❖ Redundancy ➢ Multi-DC/-AZ/-Region deployments ❖ Self-healing systems ➢ AutoScaling ❖ Automation
  • x-Project Standardization ❖ CentOS ❖ Thor - configuration management & more ➢ Puppet + custom ENC ➢ Cloud-agnostic ❖ Monitoring tools ❖ Documentation format
  • x-Environment Standardization ❖ Puppet code ❖ Thor configuration layout ❖ Infrastructure as code ➢ Repeatable, versionable environments (end-to-end) ➢ Easy to scale ➢ Great on AWS/CloudFormation
  • Infrastructure as code ❖ CloudFormation primer ➢ Stack = JSON template + parameters ❖ Supports most of AWS ➢ EC2, RDS, Route53, etc. ❖ In-place update ❖ Try it!
  • First steps ❖ Thor/AWS ❖ Manual CloudFormation management ➢ Same (evolving) template ➢ Stored in git ➢ Parameters - but who cared? ❖ Fast ➢ Dev <3 ➢ Environment explosion
  • Too good to be true...
  • A week later... ❖ First mass template update ➢ about 1 day of (boring) work
  • A few days later... Again… … and again... Too many wasted days...
  • ❖ HDD - hate-driven development * ❖ Goals ➢ All in SCM ➢ Trivial (mass) stack updates ➢ Clone stacks ➢ Multi-AWS-account use Let there be clouds! *) by @jordansissel
  • Using clouds ❖ git-like CLI ➢ clouds {clone,update,edit...} stack... ❖ Stacks ➢ dumped in current directory ➢ including parameters ❖ Use your own favorite tools
  • Clouds internals ❖ Ruby/AWS SDK (it rocks!) ➢ Research week project ➢ 3 days of work ➢ 350 LOC (half for CLI)
  • Clouds benefits ❖ Easy to promote patches ➢ Mass updates take minutes ❖ New environment in minutes ➢ Dev self-service ❖ And more...
  • Demo
  • Conclusions ❖ Scaling DevOps ➢ Standardization ➢ Automation quickly pays off DO IT!
  • Thank you!
