We’re not going to lie to you—we ran out of themes and catchy titles for the rules in this chapter. But even without a theme these rules are important. Two of these rules deal with the competencies of your team; one cautions you not to over-rely on third-party solutions for scale, and the other urges you to build the necessary competencies to be world class for each portion of your technology architecture and infrastructure. One rule outlines the foolishness of relying on stored procedures for business logic, including the hazards to scale and long-term costs to your company. Yet another rule examines the need for products to be designed from day one with monitoring in mind.
