Understanding Azure Application Gateway Pricing
Azure Application Gateway is a managed service that enables you to manage traffic to your web applications. It offers features like Web Application Firewall (WAF), SSL termination, cookie-based session affinity, and URL-based content routing. The pricing is based on several components.
Core Pricing Components
The primary cost drivers for Application Gateway are:
- Gateway Compute Units (GCUs): The performance tier of your Application Gateway. Higher tiers mean more GCUs and higher throughput.
- Data Transfer: Ingress and egress data processed by the Application Gateway.
- Additional Features: Such as the Web Application Firewall (WAF) and private IP address usage.
Pricing Tiers
Application Gateway offers different tiers to suit your needs:
- Standard_v2: Offers auto-scaling and zone redundancy for high availability.
- WAF_v2: Includes all features of Standard_v2 plus the Web Application Firewall for advanced security.
Example Pricing (Illustrative - Subject to Change)
Below is an illustrative pricing table for Azure Application Gateway. For the most accurate and up-to-date pricing, please refer to the official Azure Application Gateway Pricing page.
| Component | Description | Estimated Monthly Cost (USD) |
|---|---|---|
| Standard_v2 (Per Deployment Hour) | Base compute unit for Standard_v2 tier. Includes 2 GCUs. | ~$0.025/hour |
| WAF_v2 (Per Deployment Hour) | Base compute unit for WAF_v2 tier. Includes 4 GCUs and WAF features. | ~$0.060/hour |
| Data Processing (Per GB) | Data transferred in and out of the Application Gateway. | ~$0.008/GB |
| Private IP Address | Each static private IP address associated with the gateway. | ~$0.005/hour |
Key Factors Affecting Cost
- Instance Size/Tier: Choosing WAF_v2 over Standard_v2 will increase the hourly compute cost.
- Number of Deployments: Running multiple Application Gateway instances will multiply the hourly costs.
- Traffic Volume: Higher data transfer will directly impact costs.
- Uptime: Application Gateway is billed per hour it's deployed, regardless of traffic.
- Region: Prices can vary slightly by Azure region.
Quick Pricing Summary
- Hourly cost for the deployed gateway instance.
- Cost per gigabyte of data processed.
- Additional costs for features like WAF and static IPs.
