2908 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

  4. Architecture Cost Modelling beginner

    Every feature branch gets its own environment - one small always-on service, a managed NAT gateway, a load balancer and a small managed database. Roughly what does one idle environment cost per month at 2026 cloud list prices, and what does that imply for 60 open branches?

    On 8 August 2024 Hugging Face announced it had acquired XetHub, a 14-person storage startup, describing it as its largest acquisition to that date. Continuing on Git LFS, or building content-defined chunking in-house, were the alternatives. What cost model separates the three, and where would copying this be a mistake?
