Application Gateway Pricing
Application Gateways are a critical component in managing and securing traffic to your web applications. Understanding the pricing model for these gateways is essential for budgeting and optimizing your infrastructure costs. This article will explore the various factors that influence Application Gateway pricing and provide valuable insights into the pricing structure.
Key Takeaways
- Understanding the Application Gateway pricing model is essential for managing costs.
- Familiarize yourself with various pricing elements to optimize your infrastructure budget.
- Consider factors such as throughput, data transfer, and SSL offloading when estimating costs.
- Take advantage of pricing metrics like data processed and rules deployed to maximize value.
**Application Gateway pricing** is influenced by several factors. The location where the gateway is deployed, the number of instances required, and the tier of the gateway all impact the cost. Additionally, factors like throughput, data transfer, and SSL offloading should be considered when estimating costs for your environment.
*For example*, if your web application requires high throughput for handling a large volume of traffic, you may need to opt for a higher tier Application Gateway, which could impact the overall pricing.
Understanding Application Gateway Pricing Elements
To better understand Application Gateway pricing, it is important to familiarize yourself with the various pricing elements involved. Azure Application Gateway pricing encompasses the following components:
- Instance size: The selected instance size affects the pricing, with larger instances incurring higher costs.
- Throughput: Higher throughput requirements may require higher-tier Application Gateway instances, which can increase costs.
- Data processed: Pricing is based on data processed through the gateway, including incoming and outgoing traffic.
*One interesting point* to note is that Application Gateway pricing models allow you to take advantage of pricing metrics such as **data processed** and **rules deployed**. By optimizing these metrics, you can maximize the value you get out of your Application Gateway while minimizing costs.
Application Gateway Pricing Tiers
Azure Application Gateway offers two pricing tiers: Standard and WAF (Web Application Firewall). The Standard tier enables basic application delivery and SSL offloading, while the WAF tier includes advanced security features. Below are the details of each tier and their respective pricing structure:
| Tier | Features | Price |
|---|---|---|
| Standard | – Basic application delivery – SSL offloading – URL-based routing – Cookie-based session affinity |
– Starting at $0.025/hour for the smallest instance size |
| WAF | – All Standard tier features – Advanced web application firewall capabilities |
– Starting at $0.025/hour for the smallest instance size |
Application Gateway Pricing Examples
To help you understand how Application Gateway pricing works in real-world scenarios, here are a few examples illustrating the costs for different usage patterns:
Example 1: Low Traffic Website
If you have a web application with low traffic, considering 200,000 HTTP requests and 100,000 HTTPS requests per month, using an Azure Application Gateway Standard instance with a small instance size will cost approximately $100 per month, assuming no data transfer costs.
Example 2: High Traffic Website with SSL Offloading
For a web application with high traffic volume, generating 2 million HTTP requests and 1 million HTTPS requests per month, utilizing an Azure Application Gateway WAF instance with a medium instance size would cost around $800 per month, assuming no data transfer costs.
*One interesting thing* to keep in mind is that offloading SSL to the Application Gateway can reduce the need for SSL certificates on your backend servers, potentially saving costs on certificate management.
Optimizing Application Gateway Costs
To optimize your Application Gateway costs, consider the following strategies:
- Properly estimate your throughput requirements to select the optimal tier and instance size.
- Minimize data transfer costs by strategically deploying Application Gateways closer to your backend services.
- Regularly review and optimize rules and configurations to maximize the value of your Application Gateway.
By following these practices, you can ensure that your Application Gateway efficiently manages and secures your web applications while keeping costs under control.
