A Conversation with Amazon CTO Werner Vogels - Software Engineering Daily

"Werner Vogels is the Chief Technology Officer at Amazon, where he has played a pivotal role in shaping the company’s technology vision for over two decades. Before joining Amazon in 2004, Werner was a research scientist at Cornell University where he focused on distributed systems and scalability, both of which are concepts that would later influence the design of AWS. He holds a PhD in computer science and has authored numerous academic papers on the reliability and performance of large-scale systems.

He is known for his pragmatic, customer-focused approach to technology and for championing ideas such as “you build it, you run it,” “APIs are forever,” and more recently, Frugal Architecting, which emphasizes cost-effective and sustainable software design."

The Frugal Architect

    "frugal" is not "cheap", it is looking for best value for money spent

Cost Aware Architectures Implement Cost Controls

Werner Vogels' 6 Rules for Good API Design - The New Stack

• APIs are Forever:  Once an API is created, it should never be deleted, or changed
• Never Break Backward Compatibility: Backward capability is a must.
• Work Backwards from Customer Use Cases: come up with a minimal and simplest form of API that you can actually offer,
• Create APIs That are Self Describing and Have a Clear, Specific Purpose
• Create APIs with Explicit and Well-Documented Failure Modes
• Avoid Leaking Implementation Details at All Costs
