Azure CDN Cost Breakdown and Pricing Guide

Azure CDN offers a pay-as-you-go pricing model, where you only pay for the data transferred through the CDN.

The pricing is based on the amount of data transferred, with a minimum charge of $0.085 per GB for the first 10 TB of data transferred per month.

For data transfer between 10 TB and 40 TB, the price is $0.085 per GB, and for data transfer above 40 TB, the price drops to $0.045 per GB.

The pricing model is designed to be cost-effective for businesses with varying levels of data transfer needs.

The cost of using Azure CDN can vary depending on the type of pricing plan you choose.

Standard CDN from Microsoft (classic) is one of the options, which includes a Web Application Firewall (WAF) that protects your website from common security vulnerabilities.

Azure WAF is charged based on the WAF policies and rules configured.

Data processing costs also apply based on the amount of data processed by application gateways.

For example, Azure WAF with Application Gateway v1 (medium) costs around $0.126 per gateway-hour.

This approximates to $91.98 per month, which is a significant cost to consider.

Using Azure Content Delivery Network incurs costs beyond just the network usage charges. These costs are typically a small fraction of the overall content delivery network usage cost.

If you're using Azure Blob storage as the origin for your content, you'll also incur storage charges for cache fills, including actual GB used, transactions, and transfers in GB.

Starting October 2019, data transfer from origins hosted in Azure to content delivery network PoPs is free of charge if you're using Azure Content Delivery Network from Microsoft.

You'll incur charges for Azure compute time and Azure compute transfer if you're using hosted service delivery.

A byte-range request is a billable transaction at the content delivery network, and the transfer amount is limited to the size of the range response (plus headers).

Here are the key cost components to consider:

Standard outbound data transfer costs apply to data flowing outwards from Azure CDN’s edge servers to your website or application users.

Any HTTP(S) request that terminates at the content delivery network is a billable event, which includes all response types: success, failure, or other.

Transfer costs are a crucial aspect of using Azure CDN. You'll incur charges for data transfer from the edge to the client and from the edge to the origin.

Data transfer from the edge to the client is free for the first 10 TB per month in Zone 1, which includes North America. For Zone 1, the cost is $0.083 per GB for the next 40 TB, and $0.057 per GB for the next 100 TB.

For data transfer from the edge to the origin, the cost is $0.02 per GB in Zone 1. If you're using Azure Blob storage as the origin for your content, you'll also incur storage charges for cache fills.

Here's a breakdown of the costs for data transfer from the edge to the client and from the edge to the origin in different zones:

For data transfer from the edge to the origin, the cost is $0.02 per GB in Zone 1.

Pricing options for Azure CDN are based on various factors, including data transfer and requests. Prices are estimates only and may vary depending on the type of agreement entered with Microsoft.

Data transfer in from the client to the edge location is charged at $0.01 per GB. This rate applies to all transactions during the upcoming month, calculated based on US dollars and converted using London closing spot rates.

Azure Front Door Standard/Premium billing is based on five pricing dimensions, including base fees, outbound data transfer from edge to client, and requests incoming from client to Front Door's edge location. You can use the pricing calculator to estimate your expected monthly costs for using any combination of Azure products.

Here's a breakdown of the pricing for outbound data transfer from edge to client:

Azure Front Door (classic) offers a premium option that includes Web Application Firewall (WAF) and Private Link at no additional cost.

This means you get robust security and scalability without any extra charges for WAF and Private Link.

Azure Front Door (classic) uses the Microsoft global edge network to create fast, secure, and widely scalable web applications.

With this premium option, you can focus on building your web applications without worrying about additional costs for security and networking features.

Azure Standard CDN from Microsoft (classic) WAF Pricing states that WAF is charged separately based on the WAF policy and rules configuration.

You can purchase a subscription to the service in various ways, including monthly, quarterly, and annually.

The monthly subscription costs $29.99, while the quarterly subscription costs $89.99.

Annual subscriptions are available for $249.99, which works out to a cost of $20.83 per month.

You can also purchase a one-time access pass for $49.99, which grants you access to the service for a single month.

The pricing calculator is a powerful tool that can help you estimate your expected monthly costs for using any combination of Azure products. It's a must-use for anyone looking to get a handle on their Azure expenses.

Prices are estimates only and are not intended as actual price quotes, so keep that in mind when using the calculator. Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, and the currency exchange rate.

Azure Front Door Premium billing is based on several pricing dimensions, including base fees, outbound data transfer, and requests incoming from clients. Here's a breakdown of the pricing dimensions:

The calculator is a great way to experiment with different pricing scenarios and see how changes to your usage might affect your costs.

Using Azure Content Delivery Network (CDN) can incur additional costs beyond the primary CDN usage charges. These costs are typically a small fraction of the overall CDN usage cost.

If you're using Azure Blob storage as the origin for your content, you'll also incur storage charges for cache fills. This includes actual storage used, transactions, and transfers in GB.

For data transfer costs, starting October 2019, if you're using Azure Content Delivery Network from Microsoft, the cost of data transfer from origins hosted in Azure to CDN PoPs is free of charge. However, if you're using Edgio, the rates are as follows:

Byte-range requests are also billable transactions at the CDN. When a client issues a byte-range request, the CDN responds with only a partial portion of the content, which is a billable transaction, and the transfer amount is limited to the size of the range response (plus headers).
