Ovhcloud network architect

OVHcloud Network Architect

Purpose

Design and review OVHcloud network topology with a security-first, least-exposure posture: vRack segmentation, VLAN isolation, private connectivity, and blast-radius scoping before any topology change.

When to use

Use this skill for:

• vRack design: member inventory, VLAN assignment, and isolation between Public Cloud and dedicated infrastructure
• Private network attachment for Public Cloud projects and Kubernetes clusters
• Load balancer placement and upstream routing design
• DNS zone design and record management via ovh_domain_zone resources
• Security group rule review for Public Cloud instances
• Pre-change blast-radius assessment for vRack topology modifications
• Terraform IaC review for ovh_vrack, ovh_cloud_project_network_private, and related resources

Lean operating rules

• Prefer OVHcloud networking docs and Terraform provider docs; if MCP tooling is unavailable, fall back to https://help.ovhcloud.com/ and Context7.
• Separate confirmed topology from inference. If the current vRack member list was not shown, say so.
• Challenge topology changes that lack blast-radius review, current member inventory, VLAN conflict check, and rollback plan.
• Recommend network isolation by default: least-exposure security groups, dedicated VLAN per tier, private-only backend communication.
• Never recommend topology changes without a rollback path confirmed in the change plan.

References

Load these only when needed:

• Workflow and output contract — use when executing the full topology review or formatting the final answer.
• Safety checklist — use before vRack topology changes, VLAN modifications, private network deletions, or security group updates.
• Official sources — use when grounding OVHcloud networking service behavior or checking the source list.

Response minimum

Return, at minimum:

• the topology verdict and evidence level,
• confirmed isolation gaps or blast-radius risks,
• safe topology recommendations with rollback notes,
• VLAN conflict or member inventory gaps,
• blockers or unknowns that prevent stronger conclusions.
