FOCUS: The Universal Translator for Cloud Bills
Your Friendly Guide to the FinOps Open Cost and Usage Specification
🧩 What is FOCUS? (The Universal Translator for Cloud Bills)
Picture this: You're running a restaurant with ingredients from four different suppliers 🍅 🥩 🧀 🥦. Each supplier sends you invoices using completely different formats, item codes, and pricing structures. One lists tomatoes as "produce-red-round," another as "TOM-LRG," and yet another just calls them "item #4401".
That's exactly what happens with cloud bills from AWS, Azure, Google Cloud, and Oracle. They all speak different languages when it comes to billing.
FOCUS (FinOps Open Cost and Usage Specification) is like having a universal translator for all these different cloud bills. It's a technical specification that normalizes billing data across cloud vendors, so you:
- 🔍Don't need to learn each cloud's unique billing format
- 🧮Can easily compare costs across different providers
- ⏱️Spend less time on data normalization, more on finding savings
- 🔄Can move your FinOps skills between companies and clouds
In the simplest terms, FOCUS lets you understand all cloud bills using one common language, making cloud cost management much easier.
🏠 The Story of How FOCUS Came to Be
From multi-cloud chaos to standardized billing formats.
🌪️ The Multi-Cloud Chaos Era
Before FOCUS, the cloud billing world was pure chaos:
- 💸Each cloud provider invented their own billing format
- 📊AWS had hundreds of services with thousands of line items
- 🧩Azure used completely different terminology for the same concepts
- 🤷♂️Google Cloud structured their export yet another way
- 😱Oracle Cloud? Yep, another format to learn
The result? FinOps teams wasted precious time just trying to figure out what everything meant before they could start finding savings. Small teams were especially hurt—who has time to become an expert in four different billing systems?
🧠 The Solution: FOCUS
In 2023, the FinOps Foundation (part of the Linux Foundation) said "enough is enough" and created the FOCUS project.
Their mission was simple but ambitious:
- Create one standard format for all cloud billing data
- Get all major cloud providers to support it
- Make it freely available as an open specification
- Help FinOps practitioners focus on value, not data wrangling
By 2024, FOCUS 1.0 achieved General Availability, and all four major cloud providers—AWS, Microsoft, Google, and Oracle—announced support. By 2025, FOCUS 1.2 expanded to include SaaS and PaaS billing data, making it truly universal.
🥘 How FOCUS Works (In Plain English)
Understanding the standardized format that makes cloud bills comparable.
Think of FOCUS like a recipe standardization system. Instead of each cloud using their own secret recipe codes, FOCUS creates one standard cookbook with clear ingredient names.
🍲 The Basic Ingredients (Key FOCUS Columns)
Every FOCUS dataset includes standardized columns like:
- 📆ChargePeriodStart/End:When the charge happened
- 💰ListCost:The original "sticker price" before discounts
- 💵BilledCost:What actually showed up on your invoice
- 🏷️EffectiveCost:The true cost after all discounts and amortization
- 🏢ResourceGroup:What team or project used this resource
- 🧩ServiceCategory:What type of service this is (compute, storage, etc.)
- 🔍Region/AvailabilityZone:Where the resources are located
🧁 The Magic of Cost Normalization
The real magic happens with how FOCUS standardizes different types of costs:
ListCost
Shows original prices so you can measure discount effectiveness
BilledCost
Matches your invoices for accounting reconciliation
EffectiveCost
Shows true economic cost including amortized commitments
With these standard definitions, you can finally answer questions like "What's our true discount percentage across all clouds?" or "Which team uses the most cloud resources regardless of provider?"
🌍 The FOCUS Ecosystem (Who's Using It)
Explore the growing adoption of FOCUS across cloud providers and organizations.
FOCUS has rapidly become the universal language of cloud billing, with widespread adoption across the ecosystem:
☁️ Cloud Providers
