Understanding Cloud Platform Costs
Cloud platforms like AWS, Azure, and Google Cloud offer a vast array of services, and understanding their pricing models can be complex. This calculator provides a simplified estimate based on three fundamental components:
1. Compute Instances (Virtual Machines/Containers)
This refers to the virtual servers or containers that run your applications. Costs are typically based on:
- Number of Instances: How many virtual machines or containers you are running.
- vCPU Cores per Instance: The processing power allocated to each instance. More cores generally mean higher cost.
- GB RAM per Instance: The memory allocated to each instance. More RAM also increases cost.
- Hourly Cost: Cloud providers charge for compute resources on an hourly or per-second basis. Our calculator uses an average monthly hour count (730 hours) to project monthly costs.
Example: Running 2 instances, each with 4 vCPUs and 8GB RAM, at $0.03/vCPU/hour and $0.004/GB RAM/hour would contribute significantly to your compute bill.
2. Block Storage
This is the persistent storage attached to your compute instances, similar to a hard drive. Costs are usually calculated per gigabyte per month.
- Monthly Block Storage (GB): The total amount of storage you provision.
- Monthly Block Storage Cost per GB: The rate charged by the cloud provider for each gigabyte of storage per month.
Example: If you need 500 GB of block storage at $0.08/GB/month, your storage cost would be $40 per month.
3. Outbound Data Transfer (Egress)
This is the cost associated with data moving out of the cloud provider's network to the internet or other regions. Inbound data transfer (ingress) is often free or very low cost, but egress can be a significant expense.
- Monthly Outbound Data Transfer (GB): The total volume of data your applications send out of the cloud.
- Outbound Data Transfer Cost per GB: The rate charged for each gigabyte of data transferred out.
Example: Transferring 1000 GB (1 TB) of data out of the cloud at $0.09/GB would cost $90.
Important Considerations (Beyond This Calculator)
While this calculator covers core infrastructure, actual cloud costs can include many other factors:
- Managed Services: Databases (e.g., RDS, Azure SQL), serverless functions (Lambda, Azure Functions), message queues, etc.
- Networking: Load balancers, VPNs, dedicated connections, private IPs.
- Specialized Storage: Object storage (S3, Blob Storage), archival storage, file storage.
- Licenses: Operating system licenses (e.g., Windows Server), database licenses.
- Support Plans: Premium support tiers.
- Data Ingress: While often free, some services might charge.
- Reserved Instances/Savings Plans: Long-term commitments can significantly reduce compute costs.
- Geographic Region: Costs can vary by data center region.
This estimator is a starting point to help you budget and understand the primary drivers of your cloud infrastructure spend. Always refer to the specific pricing pages of your chosen cloud provider for exact and detailed cost breakdowns.
