Multi Cloud Cost Management Software for AWS, Azure, and GCP Cost Optimization
Three clouds, three billing formats, three different words for the same server. Costanalyst normalizes AWS, Azure, and Google Cloud into one view, so the monthly number takes minutes instead of a spreadsheet weekend.

In short
Multi cloud cost management is the practice of tracking, allocating, and reducing spend across more than one cloud provider in a single view. The hard part is not collecting the data, it is normalizing it: AWS, Azure, and Google Cloud use different billing formats, different resource names, and different discount mechanics, so a raw side-by-side comparison is meaningless. Costanalyst connects all three read-only, maps them to a common structure, allocates spend by team across providers, and prices each savings opportunity in dollars. It never changes a resource.
What you get
Multi-cloud cost management, built for finance and platform teams
One normalized view
AWS, Azure, and Google Cloud billing mapped to a common cost structure, so compute is compute and storage is storage no matter which provider issued the invoice.
Allocation that crosses providers
A team that runs services on two clouds gets one number, not two. Spend is attributed by team, product, and environment across every provider at once.
Discount coverage per cloud
Savings Plans and Reserved Instances on AWS, reservations and savings plans on Azure, committed use discounts on Google Cloud. Each checked against your real baseline, on its own terms.
Anomalies wherever they start
A spike in any provider is caught against that provider normal pattern and flagged before the invoice lands, rather than being averaged away in a combined total.
How it works
From connected to saving in four steps
Connect each cloud read-only
Grant read-only access to AWS, Azure, and Google Cloud billing. We never get permission to create, change, or delete a resource in any of them.
Normalize the data
Costanalyst maps each provider billing export to a common structure, so the same question gets the same answer regardless of which cloud it lands in.
See the whole picture
One view of total cloud spend, broken out by provider, team, product, and environment, with your SaaS subscriptions alongside it.
Act per provider
Recommendations arrive in each cloud own terms, priced in dollars. Your team makes the change, and the next invoice reflects it.
Questions people ask
Multi-cloud cost management, answered
What is multi cloud cost management?
Multi cloud cost management is the practice of tracking, allocating, and optimizing spend across more than one cloud provider from a single view. It covers unifying billing data that arrives in different formats, attributing spend to teams whose services span providers, comparing costs on a like-for-like basis, and managing each provider discount programs separately, since none of them transfer.
Why is multi cloud cost management harder than single cloud?
Because the three providers do not agree on anything that matters. They use different billing exports, different resource taxonomies, different tagging rules, and completely different discount mechanics. Add that each native console can only see its own cloud, and the total ends up being assembled by hand in a spreadsheet every month, which is slow and quietly wrong.
Can I use AWS Cost Explorer for multi cloud?
No. AWS Cost Explorer only sees AWS, Microsoft Cost Management only sees Azure, and Google Cloud billing reports only see Google Cloud. Each is free and genuinely good within its own boundary. The moment you run a second cloud, the native tools stop being able to answer your actual question, which is what total infrastructure costs and who is spending it.
What are the best multi cloud cost management tools?
It depends on what you need. Vantage and Finout are strong general multi-cloud platforms, IBM Cloudability and Flexera One lead enterprise governance, CloudZero is best for unit economics, and Costanalyst covers cloud and SaaS spend together with public self-serve pricing. We compare twelve of them honestly, including where each one beats us, in our cloud cost management tools buyer guide.
How do you allocate costs across multiple clouds?
Start by agreeing on one allocation dimension that exists everywhere, usually team or product, and map each provider native construct to it: AWS accounts and tags, Azure subscriptions and resource groups, Google Cloud projects and labels. Perfect tagging in three clouds never happens, so use rules to attribute the gaps rather than waiting for a cleanup project that will not finish.
Does multi cloud actually cost more than single cloud?
Often, yes, and it is worth being honest about it. You lose discount leverage by splitting committed spend across providers, you pay egress to move data between them, and you carry the operational cost of teams knowing three platforms. Multi cloud can still be the right call for resilience, acquisition, or specific services. Just make the decision with the cost visible rather than discovering it later.
