Cloud Computing Calculators
AWS, Azure, Google Cloud and OCI sizing and cost, virtualization, Kubernetes platforms, FinOps, CDN and edge.
Cost and capacity estimators for cloud infrastructure: compute instance pricing, reserved and spot savings, storage and data-transfer costs, and sizing for common managed services. The point is to make a bill's structure visible — which meter drives the cost — before you build.
Every price is an editable input with an example default. Providers change list prices and regional rates regularly, so replace the defaults with figures from your provider's current price list.
