How to Estimate Your Monthly Bill with Fastly CDN

Envision the ability to forecast your monthly Fastly CDN expenses with the same ease as setting your morning alarm. Having a clear financial outlook enables efficient planning, prevents unexpected costs, and allows for strategic resource allocation. Calculating your CDN expenses is more straightforward than it may initially appear, even amidst the complexities and fluctuations of usage patterns. Join us as we methodically explore this process.

The Anatomy of Fastly CDN Pricing

Understanding the various elements that contribute to your Fastly CDN bill is the first step. Fastly's pricing consists primarily of three components: Data Transfer, Request Costs, and additional features like Image Optimization or WAF (Web Application Firewall). Breaking these down:

• Data Transfer Costs: Charged per GB, varying by region. For example, North America and Europe could be priced differently than Asia or Oceania.
• Request Costs: Measured in millions of requests, this cost accounts for HTTP/HTTPS requests your applications generate.
• Add-Ons: Additional services such as Image Optimization or Web Application Firewall have their own pricing structures.

Data Transfer: The Bulk of Your Bill

Data transfer or bandwidth usage is often the most significant part of Fastly’s billing. Knowing your traffic volume helps to approximate your expenses. For instance:

• Data Transfer in North America: $0.12 per GB
• Data Transfer in Europe: $0.12 per GB
• Data Transfer in Asia: $0.19 per GB

If your website or service typically uses 10 TB (10,000 GB) per month, you can configure an estimate by multiplying the rate respective to the region by 10,000GB. If 80% of your traffic is in North America and 20% in Asia, you get:

(0.12 * 8,000 GB) + (0.19 * 2,000 GB) = $1,340

Estimating Request Costs

Requests are another critical factor. Fastly charges around $0.0075 per 10,000 requests. If your service handles 100 million requests per month:

(100,000,000 / 10,000) * 0.0075 = $75

Additional Services: More Than Just Add-Ons

While basic data transfer and request costs form the core of CDN expenses, advanced services like Image Optimization ($0.04 per image) or WAF ($0.01 per 10,000 WAF requests) add to your bill. These are often essential for performance and security, and their usage should be factored into your budget calculations.

Real-World Scenario Analysis

Consider a hypothetical SaaS company. They drive 5 TB of data transfer in North America, 3 TB in Europe, and handle 200 million requests monthly. Additionally, they optimize 500,000 images and process 50 million WAF requests. Here’s a breakdown of their estimated costs:

• NA Data Transfer: 5,000 GB * $0.12 = $600
• EU Data Transfer: 3,000 GB * $0.12 = $360
• Request Costs: (200,000,000 / 10,000) * $0.0075 = $150
• Image Optimization: 500,000 * $0.04 = $20,000
• WAF: (50,000,000 / 10,000) * $0.01 = $50

Total Estimated Monthly CDN Cost:

$600 + $360 + $150 + $20,000 + $50 = $21,160

Clearly, advanced features can have a considerable impact, highlighting the necessity of detailed usage tracking and billing projections.
