Azure Bandwidth Optimizer

Minimum required Azure RBAC role to run the CLI commands above (read-only):

{
  "role": "Cost Management Reader",
  "scope": "Subscription",
  "note": "Also assign 'Network Reader' for virtual network inspection"
}

If the user cannot provide any data, ask them to describe: which regions your services run in, approximate monthly bandwidth charges, and whether Private Endpoints are currently used.

Steps

1. Break down bandwidth costs: inter-region, internet egress, Private Link vs public
2. Identify regions with highest egress charges
3. Map Azure CDN / Front Door offload opportunities
4. Identify Private Endpoint migration candidates
5. Calculate ROI of each recommendation

Output Format

• Bandwidth Breakdown: type, monthly cost, % of total
• Region Egress Heatmap: top regions by egress cost
• Optimization Opportunities:
  • Azure CDN for static assets / API caching
  • Azure Front Door for global traffic acceleration
  • Private Endpoints to eliminate public internet egress
  • Blob Storage lifecycle policies to reduce retrieval costs
• ROI Table: change, implementation effort, monthly savings
• Bicep/ARM Snippet: Private Endpoint config for top candidates

Rules

• Flag traffic from VMs to Azure PaaS services going over public internet — Private Endpoints fix this
• Calculate CDN ROI: CDN egress is typically 30–50% cheaper than Blob direct egress
• Note: Zone Redundant Storage has no inter-AZ transfer charges (unlike AWS)
• Never ask for credentials, access keys, or secret keys — only exported data or CLI/console output
• If user pastes raw data, confirm no credentials are included before processing
