## Architecture Decision and Tradeoffs
When designing server infrastructure solutions with Windows Server, consider these key architectural trade-offs:
| Approach | Best For | Tradeoff |
|----------|----------|----------|
| Managed / platform service | Rapid delivery, reduced ops burden | Less customisation, potential vendor lock-in |
| Custom / self-hosted | Full control, advanced tuning | Higher operational overhead and cost |
> **Recommendation:** Start with the managed approach for most workloads and move to custom only when specific requirements demand it.
## Validation and Versioning
- Last validated: April 2026
- Validate examples against your tenant, region, and SKU constraints before production rollout.
- Keep module, CLI, and SDK versions pinned in automation pipelines and review quarterly.
## Security and Governance Considerations
- Apply least-privilege access using RBAC roles and just-in-time elevation for admin tasks.
- Store secrets in managed secret stores and avoid embedding credentials in scripts or source files.
- Enable audit logging, data protection policies, and periodic access reviews for regulated workloads.
## Cost and Performance Notes
- Define budgets and alerts, then monitor usage and cost trends continuously after go-live.
- Baseline performance with synthetic and real-user checks before and after major changes.
- Scale resources with measured thresholds and revisit sizing after usage pattern changes.

## Key Takeaways
- DNS provides name resolution with zones, records, and DNSSEC
- DHCP automates IP address assignment with scopes and failover
- VPN enables secure remote access with multiple protocols
- DirectAccess provides always-on VPN for domain-joined machines
- Network Policy Server delivers RADIUS authentication and 802.1X
- Software-Defined Networking offers programmatic network control
- Network performance tuning improves throughput and latency
- Monitoring tools track network health and troubleshoot issues
## Next Steps
