FinOps and cloud sustainability mutually support each other through a similar approach to conscientious and responsibility technology usage that enables workload efficiency toward sustainable outcomes that benefit our planet. If you are doing one of these – you are amplifying the other.

Within the CNCF, projects related to FinOps are also progressing. OpenCost, which can be utilized in the Inform phase of the FinOps lifecycle, is noteworthy software for those who want to focus on FinOps going forward. This session will also introduce the overview and usage of OpenCost.
