About This Tool

VM Builder provides a structured approach to defining virtual machines and exporting deployment templates. It captures OS image, CPU, memory, storage, networking, and optional features, validating inputs against safe ranges. Conceptually, a VM is modeled as a resource with explicit parameters; the tool then generates a provider-agnostic template and a human-readable summary. Users benefit from repeatable configurations, audit trails, and faster provisioning. The tool also estimates cost per hour based on region pricing and resource mix, aiding budgeting and capacity planning. Output blocks are suitable for Terraform, CloudFormation, or cloud-init, enabling seamless IaC workflows. Use cases include evaluating VM shapes for development, staging, and production, or rapidly bootstrapping standardized environments across teams. Unique value lies in integrated validation, presets for common shapes, and exportable templates with consistent resource naming and tagging. Core features include multi-field input, range validation, presets, cost estimation, and deployment-ready templates; optional fields support GPU, licensing, SSH keys, and tags for governance and security. Example: a 4 vCPU, 16 GB RAM, 100 GB SSD VM in us-east-1 yields a YAML/JSON template and a cost estimate for budgeting and procurement decisions.

How to Use

  1. Provide inputs: specify VM name, OS image, vCPU, RAM, disk size, storage type, and region.
  2. (Optional) Add advanced options: GPU, licensing, SSH keys, tags.
  3. Run calculation: tool validates inputs and generates a deployment-ready block.
  4. Review outputs: YAML/JSON snippet, cost estimate, and recommended defaults.
  5. Export or copy: save the config and pricing summary to use in cloud provisioning.

Frequently Asked Questions

Find Quick Answers

What outputs does VM Builder generate?
VM Builder outputs deployment-ready templates in YAML and JSON plus a cost estimate per hour. Templates are compatible with IaC tooling (Terraform, CloudFormation) and can be adapted for cloud-init or provider-specific formats.
Can I compare configurations?
Yes. You can create multiple presets or configurations, run validations, and view side-by-side summaries and cost estimates to select the best fit for capacity and budget.
Are pricing estimates exact?
Estimates use region-based unit costs and current storage multipliers. Final billing depends on provider pricing, actual usage, and any discounts or commitments.
What OS images are supported?
Common Linux and Windows images are supported as image IDs or aliases. The tool validates OS-image-region compatibility and permits custom image IDs for enterprise catalogs.
