Are instances with the same vCPU and memory truly equivalent?

Not always. CPU performance varies by generation, architecture (Intel vs. AMD vs. ARM), and clock speed. Network and storage performance also differ. A 4-vCPU instance on one provider may outperform an equivalent spec on another. Benchmark your specific workload for accurate comparison.

How often do cloud providers change pricing?

Major price changes happen a few times per year, usually tied to new instance generation launches. All three providers have committed to not raising prices on existing generations. New generations typically offer better price-performance. This tool uses representative pricing that should be verified against current provider pricing pages.

Should I optimize for the cheapest provider per workload?

Price is one factor, but also consider data transfer costs between clouds, operational complexity of managing multiple providers, team expertise, service ecosystem lock-in, and compliance requirements. Multi-cloud is most valuable for redundancy and avoiding vendor lock-in rather than per-workload cost optimization.

About This Tool

The Multi-Cloud Instance Compare tool lets you compare equivalent compute instances and pricing across AWS, Azure, and GCP side-by-side. Enter your resource requirements or select specific instance types and see how they map across providers with current pricing estimates. This tool is essential for multi-cloud cost optimization and migration planning.

When to Use This Tool

•Comparing the cost of running identical workloads across AWS, Azure, and GCP to find the cheapest provider.
•Mapping on-premises server specs to equivalent cloud instances across all three providers during lift-and-shift migration.
•Building cost comparison reports for management when evaluating multi-cloud or cloud-switching strategies.
•Identifying pricing anomalies where one provider is significantly cheaper for a specific instance configuration.
