How is the world's largest storage system, AWS S3 built? I found the best person to talk about this: Mai-Lan Tomsen Bukovec, who has been heading up S3 for 13 years (!) S3's scale is something else (tens of millions of hard drives, eleven 9s of durability (!!) and heavy usage of formal methods, microservices dedicated to durability, amongst others.) Watch or listen: • YouTube: • Spotify: • Apple: Brought to you by: • @statsig — ⁠ The unified platform for flags, analytics, experiments, and more. • @SonarSource – The makers of SonarQube, the industry standard for automated code review. Check out their latest State of Code Developer Survey report: • @WorkOS – Everything you need to make your app enterprise ready.

One thing that got my attention is how much the AWS team thinks about "the commitment to the byte." As Mai-Lan told me: "Every day I come in, where I feel a personal sense of commitment to your byte, to the preservation of your byte, to the usefulness of your byte, to the ability for you to think about what your application does next and not the types of storage that you need or how you grow it. And that deep sense of ownership and that deep sense of commitment is a very common thread across our data teams. We know that at the end of the day, every modern business is a data business."
