Cloud Provider Support

Cloud Provider Support

AWS, Azure, Google Cloud, and Oracle Cloud all support native FOCUS-formatted billing exports, though implementation maturity and version support vary across providers.

The Big Four

All four major cloud infrastructure providers committed to native FOCUS support alongside the v1.0 GA release in June 2024. This was a pivotal moment — it meant practitioners could get standardized billing data directly from their providers without needing the focus-converter.

Amazon Web Services (AWS)

Status: FOCUS 1.0 in General Availability

AWS provides FOCUS-formatted data through the Data Exports feature in the Billing and Cost Management console. Key details:

  • Access via console, CLI, or SDKs
  • Export format: Parquet (recommended) or CSV
  • Based on the CUR (Cost and Usage Report) infrastructure
  • AWS includes provider-specific columns with the x_ prefix alongside FOCUS columns
  • Available under Data Exports → create a FOCUS 1.0 export

AWS was an early mover on FOCUS support, previewing FOCUS exports before the GA release and making them generally available alongside the v1.0 announcement.

Microsoft Azure

Status: FOCUS 1.2 billing exports in Public Preview (as of late 2025)

Azure has been one of the most active FOCUS supporters, both in specification development and implementation:

  • FOCUS data is available through Azure Cost Management exports
  • Microsoft publishes an extensive “Learning FOCUS” blog series covering cost columns, charge types, pricing models, commitment discounts, and prices/quantities
  • Azure’s FinOps toolkit includes FOCUS-formatted sample data
  • Microsoft’s FinOps team is a significant contributor to the specification itself
  • Some fields in the v1.2 preview exports are still being populated

Google Cloud Platform (GCP)

Status: FOCUS 1.0 support

GCP takes a BigQuery-native approach to FOCUS:

  • Provides a FOCUS BigQuery view over your billing dataset
  • Includes a Looker Template for visualizing FOCUS-formatted data
  • The BigQuery approach means FOCUS data is immediately queryable via SQL without exporting files
  • Google Cloud’s blog highlighted FOCUS v1.0 GA as a milestone for cloud cost transparency

Oracle Cloud Infrastructure (OCI)

Status: FOCUS support in cost reports

Oracle provides FOCUS-formatted data through their cost management tools. As one of the four founding cloud supporters, OCI’s inclusion demonstrates FOCUS’s reach beyond the “big three” hyperscalers.

Vendor Support for FOCUS 1.2

The Linux Foundation’s December 2025 press release (alongside the v1.3 launch) announced expanded vendor support for FOCUS 1.2, indicating that cloud providers are actively implementing the newer spec versions. The pace of adoption has been encouraging — providers are generally tracking within 6–12 months of spec releases.

Native vs. Converter Approach

ApproachProsCons
Native FOCUS exportProvider-maintained, always current, no tooling overheadVersion support may lag latest spec, provider-specific quirks
focus-converterWorks with historical data, transparent mapping logicRequires Python tooling, best-effort mapping, maintenance burden

For new implementations, native exports are the recommended approach. The converter is primarily useful for historical data conversion and for providers not yet supporting native FOCUS.

Key Points

  • All four major cloud providers (AWS, Azure, GCP, Oracle) support native FOCUS exports
  • Implementation maturity varies — Azure is furthest along with v1.2 preview support
  • Provider-specific data is preserved through x_ custom columns
  • The GCP approach (BigQuery view) is architecturally different from AWS/Azure’s export-based approach
  • Over 90% of enterprises use multi-cloud — making cross-provider FOCUS data critically useful
