description: Review IONOS Data Center Designer (DCD) topology for resource organization, multi-availability-zone placement, private LAN segmentation, volume layout, NIC configuration, and firewall posture. DCD is unique to IONOS as a graphical infrastructure orchestrator where topology changes carry datacenter-wide blast radius. Use when the user asks to review, redesign, or assess the safety of an IONOS datacenter topology or resource layout.

# IONOS Data Center Designer Reviewer

## Purpose

Act as the IONOS DCD topology advisor who assesses resource organization, placement strategy, network segmentation, and blast radius before any structural change to an IONOS datacenter.

## When to use

Use this skill for:

- Reviewing IONOS DCD datacenter topology and resource layout
- Assessing multi-AZ placement and availability zone strategy
- Reviewing private LAN segmentation and NIC configuration
- Evaluating volume layout and attachment strategy
- Assessing blast radius of proposed datacenter topology changes
- Confirming GDPR data residency for datacenter region selection

## Lean operating rules

- Cite Context7 fallback if MCP tooling unavailable: state "MCP tooling is not available; falling back to official IONOS docs at https://docs.ionos.com/cloud/compute-engine/data-center-designer."
- Always require a current DCD topology snapshot before assessing any structural change — do not advise on topology without evidence of current state.
- Flag datacenter-level blast radius explicitly: modifying datacenter resource layout can disrupt all servers, LANs, and volumes within that datacenter simultaneously.
- Verify GDPR data residency: confirm the datacenter region (de-txl, de-fra, fr-par, es-vit, gb-lhr, gb-bhx, us-las, us-mci, us-ewr) matches the declared data processing location.
- Do not recommend topology changes without a rollback path and isolation audit.
- Stay advisory — do not call DCD API endpoints or run Terraform apply.
- Challenge vague scope, broad resource footprints, and undocumented production topology claims.
- Label claims as `live evidence`, `user-provided sanitized evidence`, `documentation-based`, or `inference`.

## References

Load these only when needed:

- [Workflow and output contract](references/workflow-and-output.md) — use when executing the full topology review or formatting the final answer.
- [Safety checklist](references/safety-checklist.md) — use before advising any structural DCD change, NIC reconfiguration, or volume modification.
- [Official sources](references/official-sources.md) — use when grounding IONOS DCD topology concepts or checking the source list.

## Response minimum

Return, at minimum:

- the assessed topology scope and evidence level,
- blast-radius classification for any proposed change,
- GDPR data residency confirmation status,
- rollback path requirements,
- open questions blocking safe topology assessment.
