Here’s the same list but unconstrained by a fixed-width text box so you can actually read it. 🙂
- 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.
- The entire system must be deployable using source media and text files.
On Buying Software
- Keep the components in the infrastructure simple so it will be better understood.
- All products must authenticate and authorize from external, configurable sources.
- Use small tools that interoperate well, not one “do everything poorly” product.
- Do not implement any product that no one in your organization has administered.
- “Administered” does not mean saw it in a rigged demo, online or otherwise.
- If you must deploy the product, hire someone who has implemented it before to do so.
- Do not author any code you would not buy.
- Do not implement any product that does not provide an API.
- The provided API must have all functionality that the application provides.
- The provided API must be tailored to more than one language and platform.
- Source code counts as an API, and may be restricted to one language or platform.
- The API must include functional examples and not requre someone to be an expert on the product to use.
- Do not use any product with configurations that are not machine parseable and machine writeable.
- All data stored in the product must be machine readable and writeable by applications other than the product itself.
- Writing hacks around the deficiencies in a product should be less work than writing the product’s functionality.
- Keep the disparity in your architecture to an absolute minimum.
- Use Set Theory to accomplish this.
- Do not improve manual processes if you can automate them instead.
- Do not buy software that requires bare-metal.
- Manual data transfers and datastores maintained manually are to be avoided.
