This tier is available from the moment you create your AWS account and allows you to use the service for free within certain limits.</p> <ul> <li><strong>1 TB Data Transfer Out:</strong> 1 TB of data transfer out to the internet is free each month.</li> <li><strong>10 Million Requests:</strong> 10 million HTTP or HTTPS requests per month are free.</li> <li><strong>2 Million Function Invocations:</strong> You get 2 million free invocations for CloudFront Functions monthly.</li> </ul> <h2 id="data-transfer">Regional Data Transfer Costs</h2> <p>Data transfer usually makes up the largest portion of CloudFront costs. Prices vary depending on the region (Edge Location) from which data is served to the user. For example, data transfer in the US or Europe is generally cheaper than in South America or Australia.</p> <h2 id="request-pricing">HTTP and HTTPS Request Pricing</h2> <p>Every request your users make to access your content is billed. HTTPS requests can be slightly more expensive than HTTP requests, but using HTTPS is standard for security.</p> <pre><code class="language-bash"># Example Cost Calculation (Approximate Values) # 1 Million HTTPS Requests (USA): ~$1.00 - $1.20 # 10 GB Data Transfer (USA): ~$0.85 (After the first 1TB) </code></pre> <h2 id="origin-shield">CloudFront Origin Shield</h2> <p>Origin Shield provides an additional caching layer to reduce the load on your origin server. This feature is optional and incurs an additional cost. However, it can save total costs by reducing scaling costs for your origin server.</p> <h2 id="invalidation">Cache Invalidation</h2> <p>When you update your content, you need to perform an "invalidation" to clear the old cache. The first 1,000 paths are free each month. Afterwards, a small fee (approximately $0.005) is charged per path.</p> <h2 id="optimization">Cost Optimization Tips</h2> <p>You can follow these strategies to keep CloudFront costs under control:</p> <ol> <li><strong>Increase Cache Duration (TTL):</strong> Keep your content in the cache longer to reduce origin traffic and the number of requests.</li> <li><strong>Use Security Savings Bundle:</strong> You can save up to 30% by making a long-term commitment.</li> <li><strong>Use Compression:</strong> Reduce the size of transferred data with Gzip or Brotli compression.</li> </ol> <h2 id="faq">Frequently Asked Questions (FAQ)</h2> <div class="faq-item"> <h3>How long does the CloudFront free tier last?</h3> <p>The CloudFront free tier is valid for the life of your AWS account and renews every month (within limits like 1 TB data transfer).</p> </div> <div class="faq-item"> <h3>Are HTTPS requests more expensive than HTTP?</h3> <p>Yes, generally HTTPS requests are charged slightly higher than HTTP requests, but the difference is very small.</p> </div> <div class="faq-item"> <h3>Should I use Origin Shield?</h3> <p>If your origin server is struggling under high traffic or receiving traffic from many regions, Origin Shield can be a cost-effective solution.</p> </div> <div class="faq-item"> <h3>Why do data transfer charges vary by region?</h3> <p>Since infrastructure and internet bandwidth costs vary globally, AWS reflects these costs in regional pricing.</p> </div> <h2 id="resources">Useful Resources</h2> <ul> <li><a href="https://aws.amazon.com/cloudfront/pricing/" target="_blank" rel="noopener noreferrer">AWS Official Pricing Page</a></li> <li><a href="https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/Introduction.html" target="_blank" rel="noopener noreferrer">Amazon CloudFront Developer Guide</a></li> <li><a href="https://www.devopsn.cloud/tech/aws-consultancy">AWS Consultancy Services</a></li> <li><a href="https://www.devopsn.cloud/tech/kubernetes-consultancy">Kubernetes Consultancy Services</a></li> <li><a href="https://www.devopsn.cloud/">DevOpsN Cloud Home</a></li> </ul> <p>The technical information and pricing examples in this post are compiled from the <a href="https://awsfundamentals.com/blog/amazon-cloudfront-pricing" target="_blank" rel="noopener noreferrer">AWS Fundamentals</a> blog.</p> <p>Kaynak / Source: https://awsfundamentals.com/blog/amazon-cloudfront-pricing</p>
