Cloud adoption has never been stronger, growing at 22% year-over-year to reach $95.3 billion in Q2 of 2025 alone.[1] However, it’s clear that many businesses are struggling with cloud cost control and performance optimization. Depending on the source, cloud waste averages from 32% to 47% of cloud budget, with 75% of surveyed organizations reporting increasing cloud wastage.[2]
Cost control and optimization becomes even more challenging with multi-cloud environments, as providers offer starkly different pricing and usage structures. For example, some base costs on compute power while others use storage or data transfer. That means cost control and optimization for multi-cloud environments requires more than contract management or the elimination of unnecessary add-ons. Rather, it’s an integrated approach to optimization, focusing on maximizing usage, improving efficiency, and extracting real value from multi-cloud environments.
As we point out in a past article comparing the biggest cloud providers—AWS, Azure, and Google Cloud—each provider handles billing and tracks usage in very different ways. This makes it very difficult to compare costs and benefits for organizations who do not have internal or third-party experts on cloud optimization. For example, AWS charges by the hour for cloud servers; Azure tracks daily usage; GCP uses both compute and memory.[3]
Additionally, without specific expertise in each cloud provider, organizations suffer from “semantic debt”, where the terminology, metrics, and billing structures differ so much that less obvious fees and costs cannot be anticipated and thus avoided.[4] The outcome of these issues means that 65% of companies are essentially “guesstimating” their costs and data management in a multi-cloud environment.[5]
While the nature of multi-cloud usage and billing presents inherent challenges, there are steps to illuminate blind spots and reduce unexpected cost spikes, including:
Not only do cloud providers bill according to different metrics and usage factors, but each cloud provider also uses different billing formats—ranging from extremely detailed CSVs to BigQuery. A “tidy data” approach for billing information, with one observation per row, one variable per column, and one value per cell, can help to normalize billing information.[6] While it does require effort to set up, the payoff is worth the effort. It provides a uniform structure for diverging billing formats, and this normalized data can be combined with APIs and microservices going forward.
Standardized tagging is a powerful tool for multi-cloud cost allocation. Some basic strategies across cloud platforms include:
While the actual tagging strategy should be determined by your organization’s structure, there are multiple approaches to implementation. Additionally, your platform provider may be able to offer specific tagging tools. For example, AWS Service Control Policies, Azure Policy, and GCP Organization Policy with automation are all tools that can help to normalize tagging.[8]
Third-party dashboards can bring billing information from multiple sources into a “single pane of glass.” While the choice of dashboard is highly dependent on the organization’s specific needs, leading platforms can show critical insights, including:[9]
Rightsizing helps match instance types and sizes to actual workload needs. While simple in concept, it’s powerful when properly implemented, cutting multi-cloud costs by 30-60%.[10] Some basic strategies include:
As different platforms bill by different usage factors, businesses can use a detailed rightsizing approach to cut costs, choosing providers whose instance types best match specific tasks and qualifications.[11]
Once you fully understand your usage and each platform’s most optimal applications, commitment-based discounts can slash pricing across providers by up to 72%.[12] While standardized instances offer the greatest savings, convertible reserved instances can combine savings with flexibility.
For those who go further in depth, you can combine different reserved instances for specific applications. For example, you could use AWS Reserved Instances for regular workloads and Azure Reserved Instances for critical apps.[13]
Idle resources are an obvious drain on budgets, but the challenge is identifying them in time to make adjustments that produce savings. By setting automated alerts according to resource deployment, administrators can spot and avert potential waste before monthly billing reviews. Some potential examples include automatic shutdowns of non-production environments during off-hours, resources that scale based on demand, and systems that clean up unused resources.[14]
While many management approaches consider cost management as a secondary consideration, FinOps makes financial responsibility an integral part of all technical decisions. In practice that means organizations should define ownership of cloud spending, resource provisioning, and cost monitoring across teams along with clear budget thresholds.[15]
By combining this FinOps approach to cloud computing with automation tools, organizations can ensure that cloud expenses correlate to business value.
Cloud providers offer native tools to track costs, but they are not designed to play well across platforms. There are several third-party tools that seek to bridge the gap between providers, offering data standardization across multi-cloud environments.
While the choice is dependent on the individual organization’s tech stack and needs, key selection factors include:[16]
As cloud adoption continues to accelerate, the complexities of multi-cloud billing present both challenges and opportunities to optimize cloud computing costs. By implementing comprehensive visibility through normalized billing and consistent tagging, strategically optimizing resources across platforms, and automating cost controls with FinOps best practices, businesses can make cloud spending both predictable and predicated upon real value.
However, the reality is that multi-cloud cost control and performance optimization requires extensive knowledge of each cloud provider. Rather than navigating this complex landscape alone, a cloud and infrastructure specialist like IPC Tech can develop a customized approach for your specific business needs and objectives.
