Overview of Application Gateway Pricing

Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. The pricing for Application Gateway is based on several factors, including the tier selected, the number of instances, and the data processed.

Pricing Tiers

Application Gateway offers two primary tiers, each with different features and capabilities:

  • Standard v2: Ideal for most common load balancing scenarios, offering auto-scaling and zone redundancy.
  • WAF v2: Includes all features of Standard v2, plus Web Application Firewall (WAF) capabilities to protect against common web vulnerabilities.

Key Pricing Components

  • Gateway Fee: A fixed hourly charge for each Application Gateway deployment, based on the tier.
  • Data Processed: Charged per Gigabyte (GB) of data processed by the gateway.
  • Rules Engine (WAF): For WAF tiers, there's a separate charge for the WAF rules processing per GB.

Understanding Your Costs

Your total cost for Application Gateway will be the sum of:

  • The hourly gateway fee (depending on your chosen tier and region).
  • The cost of data processed through the gateway.
  • If using WAF v2, the cost of WAF rules processing.

Consider the number of instances, expected traffic volume, and required security features when estimating costs.

Additional Considerations

  • High Availability: Ensure you understand pricing implications for zone-redundant or multi-region deployments.
  • Custom Domains and SSL Certificates: While not directly charged by Application Gateway, managed certificates or custom domain services might incur separate costs.
  • Network Egress: Data egress charges from Azure may apply depending on your network topology.
