Rules

On Infrastructure

• There is one system, not a collection of systems.
• The desired state of the system should be a known quantity.
• The "known quantity" must be machine parseable.
• The actual state of the system must self-correct to the desired state.
• The only authoritative source for the actual state of the system is the system.
