Azure Application Gateway Pricing

Home > Documentation > Application Gateway > Pricing

Pricing Overview

Azure Application Gateway pricing is based on the following components:

  • The number of Application Gateway instances deployed.
  • The amount of data processed by the Application Gateway.
  • The availability zones used (if applicable).
  • Optional features like Web Application Firewall (WAF).

Pricing Tiers

Application Gateway offers several tiers to suit different needs:

  • Standard V2: Cost-effective for common workloads.
  • WAF V2: Includes Web Application Firewall capabilities for enhanced security.
  • WAF_v2_AZ: WAF V2 with zone redundancy for high availability.
Feature/Component Standard V2 (per instance/hour) WAF V2 (per instance/hour) WAF_v2_AZ (per instance/hour) Notes
Application Gateway Instance $0.025 $0.025 $0.025 Includes compute for load balancing, SSL offload, etc.
Data Processed (per GB) $0.0035 $0.0035 $0.0035 Applies to all data passing through the gateway.
Web Application Firewall (WAF) Not included $0.016 $0.016 Add-on for WAF functionality.
Availability Zones N/A N/A $0.005 For zone-redundant deployments.

Important Note:

Prices are estimates and may vary by region. For precise pricing, please use the Azure Pricing Calculator.

Example Scenario

Let's consider a scenario with 2 Standard V2 instances running for 30 days (720 hours) and processing 1 TB (1024 GB) of data:

Application Gateway Instance Cost: 2 instances * 720 hours * $0.025/hour = $36.00
Data Processed Cost: 1024 GB * $0.0035/GB = $3.58
Total Estimated Cost: $39.58

This is a simplified example. Actual costs may vary based on your specific configuration and usage patterns.

Key Pricing Factors

Instance Count

The primary cost driver is the number of Application Gateway instances you deploy. More instances provide higher throughput and availability but also increase costs.

Data Transfer

All data passing through the Application Gateway incurs a cost per gigabyte. This includes both ingress and egress traffic.

WAF Add-on

If you enable the Web Application Firewall, there's an additional hourly charge per instance for the WAF functionality.

Availability Zones

Deploying Application Gateway across multiple Availability Zones (for zone redundancy) incurs a small additional hourly cost per instance.
