Assumptions

• this environment is like a long running customer environment
  • tools already installed

  • everything managed
  • real certs / self signed too (to replicate reality)
• contract is from customer to chef
  • story is of top value
• environment is shared across all users
  • intent is to create customer (enterprise) empathy and expose flaws in our tools in customer-like environments
• dev work in these environments may break the environment
  • follow our own support protocols to restore service
  • follow bug flow to remediate issues
• can be used to validate break/fix
• values solution approach approach over practitioner approach

Requirements
