FinOps
FinOps is the practice of managing cloud spend as a shared responsibility between engineering, finance, and leadership — using real-time cost data to make trade-offs, instead of finding out the bill was too high after the invoice arrives.
FinOps (a blend of “finance” and “DevOps”) is a set of practices for managing cloud costs collaboratively, instead of treating the bill as something only finance sees once a month. The core idea: engineers who provision cloud resources need to see the cost of what they provision, in near real time, so cost becomes part of the same decision as performance or reliability — not a surprise found weeks later.
A mature FinOps practice usually has three phases running continuously: Inform (everyone can see what they’re spending and why), Optimize (acting on that visibility — right-sizing, Reserved Instances, Spot, cleaning up unused resources), and Operate (making cost a standing part of how the team plans and reviews work, not a one-time cleanup project).
The most common failure mode is treating FinOps as a single audit rather than an ongoing practice — costs creep back up within months if nobody owns visibility after the initial cleanup.
