What is FOCUS™?

The FinOps Cost and Usage Specification (FOCUS™) is an open-source specification that defines clear requirements for cloud vendors to produce consistent cost and usage datasets.

Supported by the FinOps Foundation, FOCUS™ aims to reduce complexity for FinOps Practitioners so they can drive data-driven decision-making and maximize the business value of cloud, while making their skills more transferable across clouds, tools, and organizations.

“With FOCUS™, we believe your billing data will be even more accessible and useful so you can get more of your time back and focus on cost management, cost savings, and cost optimization."

Anne Johnston

VP of Engineering Cloud Costs

”The basics of good decision-making and execution require clarity of information. FOCUS™ goes a long way to making that possible and we look forward to even greater innovation in the years ahead.”

Tim O'Brien

Senior Director of Engineering

“We’re thrilled to see FOCUS™ gathering momentum. Having a vendor-neutral view of all cloud resources will enable us to better engage with cloud partners and better serve our customers and shareholders.”

Who uses FOCUS™?

FinOps Practitioners

With unified billing data, you spend more time on FinOps and less time on data normalization, and can refocus efforts on iteratively improving high-priority FinOps Capabilities. With FOCUS™, Practitioners also gain transferrable data skills.

Cloud Vendors

FOCUS™ helps Cloud Service Providers, SaaS Vendors, and other Independent Software Vendors (ISVs) who generate cloud billing data by easing adoption of their offerings and accelerating usage of cloud infrastructure and software.

FinOps Vendors

With FOCUS™, FinOps vendors needn’t spend development resources building data normalization functionality. Instead, those resources can be spent developing support for other FinOps Capabilities that customers need.

The FOCUS™ initiative aims to build and maintain an open standard for cloud billing data and garner adoption across all major cloud vendors.

Version 1.0 introduces common taxonomy, terminology, and metrics for billing datasets produced by large Cloud Service Providers (CSPs). The Specification, however, aims to be extensible to other cloud SaaS billing datasets, including networking, observability, and security tools.

Future updates are expected to add support for SaaS providers and even on-premises datasets.
