Much like the array of AWS services, CloudFront stands out with its flexible cost structure, devoid of any minimum commitments. With Amazon CloudFront, you pay only for the resources you consume, ensuring cost-efficiency and scalability. This approach presents a stark contrast to self-hosting, where the financial and operational burdens of managing a network of cache servers across various internet locations can be overwhelming. Additionally, AWS CloudFront eliminates the necessity of over-provisioning capacity to cater to potential traffic surges, allowing you to dynamically adapt to demand without unnecessary expenses. Amazon CloudFront also uses techniques such as collapsing simultaneous viewer requests at an edge location for the same file into a single request to your origin server. This reduces the load on your origin servers reducing the need to scale your origin infrastructure, which can bring you further cost savings.
