A whole generation of developers has been told “cloud-first.” This column collects data, case studies, and commentary on the real economics—and traps—of public cloud rental models.

A user consulted about distributed databases, but he wasn’t dealing with data bursting through server cabinet doors—rather, he’d fallen into another cloud computing pig-butchering scam.

Tencent Cloud’s epic global outage after Double 11 set industry records. How should we evaluate and view this failure, and what lessons can we learn from it?

S3 is no longer “cheap” with the evolution of hardware, and other challengers such as cloudflare R2.

Hardware is interesting again, developments in CPUs and SSDs remain largely unnoticed by the majority of devs. A whole generation of developers is obscured by cloud hype and marketing noise.

At the SACC 2023 FinOps session, I fiercely criticized cloud vendors. This is a transcript of my speech, introducing the ultimate FinOps concept — cloud-exit and its implementation path.

Public cloud margins worse than sand mining—why are pig-butchering schemes losing money? Resource-selling models heading toward price wars, open source alternatives breaking monopoly dreams!
