GreenOps: seven levers that cut 30% of your cloud bill.

GreenOps is the application of FinOps and SRE practices to a dual goal: reducing both the cost AND the carbon footprint of an infrastructure, without degrading SLOs. Where FinOps looks first at the bill and SRE at reliability, GreenOps treats both as a single budget: every euro and every gram of CO2 spent must be justified by delivered value. The founding principle fits in one sentence: the most sustainable code is the code you don't write, and the cheapest resource is the one you don't provision.

On the infrastructure of a mobility scale-up, a micro-services rework combined with systematic profiling and dynamic scaling cut the cloud bill by 30% at constant service, same SLOs, better resilience. On the AI inference workload of a European bank, moving to a hybrid RAG architecture divided inference cost by 10. These are not one-shot optimizations: every lever is instrumented (cost/carbon budgets, observability) to prevent drift once the team has moved on.

The seven levers to activate range from the fastest (right-sizing, shutting down idle environments, choosing low-carbon regions) to the most structural (application profiling, dynamic scaling, frugal runtimes, event-driven architecture). None requires sacrificing performance: done well, they improve it, because a lean system is a system you understand.
