Use Things you Understand! Learn the fundamentals to understand the layers of abstraction! And remember that we don't live in a world with unlimited resources!These are advice from our recent conversation with Ernst Ambichl, Chief Product Architect at Dynatrace, who has started his performance career in the late 80s building the first load testing tools for databases which later became one of the most successful performance engineering tools in the market.Tune in and learn about how Ernst has evolved from being a performance engineer to become an advocate for "Designing and Architecting for Performance". Ernst explains how important good upfront analysis of performance requirements and characteristics of the underlying infrastructure is, how to define baselines and constantly evaluate your changes against your goals.On a personal note: I want to say THANK YOU Ernst for being one of my personal mentors over the past 20+ years. You inspired me with your passion about performance and building resilient systems
