Design principles for cloud-based systems

Key design principles, addressing the challenges of systems on the cloud:

• Design to run at massive scale (see 20 Obstacles to Scalability).
• Design with the expectation of subcomponent failure (see Chapter 7 of The Datacenter as a Computer, 2d. Ed.).
• Control latency caused by the high-percentile instances (see The Tail at Scale).
• Test failure resistance by inducing failures in production systems (see The Antifragile Organization).
• For each service, trade off consistency, availability, and mitigation (see CAP Twelve Years Later).
• Design for performance monitoring and adjusting the system (see On Designing and Deploying Internet-scale Services).
