What is FOCUS?

FOCUS (FinOps Open Cost & Usage Specification) is an open standard for cloud billing data that provides consistent, normalized cost and usage data across cloud providers like AWS, Azure, and Google Cloud.

  • Standardize cost data across cloud providers
  • Simplify financial analysis and reporting
  • Enable consistent FinOps practices
  • Improve cost optimization and allocation
