Overview

Microsoft’s current application-delivery service is Azure Front Door Standard or Premium. Azure CDN Standard from Microsoft (classic) remains available to existing profiles but retires on 30 September 2027. Microsoft no longer allows new profile or domain onboarding for the classic tier and directs customers to Front Door Standard or Premium.

Network & Architecture

Azure Front Door delivers static and dynamic content over Microsoft’s global network. The classic Azure CDN tier and current Front Door tiers are separate products with different capabilities and retirement states; this profile does not combine their footprints or feature claims.

Pricing

Azure Front Door pricing depends on the tier, base fees, requests, data transfer, and optional security use. Azure CDN Standard from Microsoft (classic) has a separate retiring price schedule. Use Microsoft’s current calculators and pricing pages for a dated estimate; no example per-GB rate is recorded here.

Integrations & DevEx

Microsoft documents a migration path from Azure CDN Standard from Microsoft (classic) to Front Door Standard or Premium. Review custom domains, certificates, rules, WAF policies, monitoring, and deployment automation before migration, then update DNS as directed after validation.

When it fits

  • The application already uses Azure and needs global static or dynamic delivery.
  • The team can select Front Door Standard or Premium based on documented security requirements.
  • Operations can test the tier-specific rules, certificates, logs, and migration path.

When it doesn’t

  • A new deployment is being designed around Azure CDN Standard from Microsoft (classic), which is retiring.
  • The project assumes the classic CDN, Front Door Standard, and Front Door Premium have identical features or prices.
  • The migration cannot be completed and verified before the documented retirement date.
