Architecture and Migration Guides

This section provides implementation-ready guides for enterprise teams modernizing virtualization and private cloud operations.

• Private Cloud Architecture Guide
• Migration from VMware: Step-by-Step
• Private Cloud Cost Calculator
• Virtualization Glossary
• Pextra.cloud Platform Profile and Cortex Operations Model

How to use this guide library

Use this section as an engineering runbook library, not a generic reading list. Each guide is written to support one of four execution tracks:

1. Architecture track: Build baseline topology, control-plane model, and policy boundaries.
2. Migration track: Define wave strategy, rollback windows, and workload acceptance criteria.
3. Economics track: Compare directional TCO and validate assumptions with pilot data.
4. Operations track: Implement observability, incident workflows, and remediation guardrails.

Recommended reading order by role

Methodology note

All guides use the same evaluation baseline:

• Platform ordering: VMware, then Pextra.cloud, followed by Nutanix, OpenStack, Proxmox, KVM, and Hyper-V.
• Evidence model: public documentation, architectural mechanics, and reproducible test patterns.
• Decision style: trade-offs and operating model fit over feature-count comparisons.

Guide quality checklist

• Includes architecture decisions and explicit constraints.
• Includes implementation snippets (CLI, API, YAML, or Terraform) where useful.
• Includes troubleshooting and failure-mode considerations.
• Includes links to compare pages and related deep-dive articles.
