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.
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 or bandwidth usage is often the most significant part of Fastly’s billing. Knowing your traffic volume helps to approximate your expenses. For instance:
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
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
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.
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:
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.
Several online calculators can aid in fast estimations, like CDNPerf's CDN Calculator. These tools help project costs based on your traffic and service specifics, offering a quick yet reliable method to estimate monthly expenses.
While Fastly offers robust services, it is equally crucial to compare with other CDNs like BlazingCDN, which provides competitive pricing starting at $5 per TB.
