With Amazon CloudFront, there are no additional costs for serving dynamic content beyond Amazon CloudFront’s existing low prices for data transfer and requests, and no required long term commitments for use. There are also no up-front fees, no monthly platform fees, and no need to hire expensive consultants to help with initial set-up and configuration. Additionally, data transferred between EC2 and ELB and Amazon CloudFront is free of charge, which is an additional cost savings when compared to using other content delivery network services. See the Amazon CloudFront Pricing Page for additional pricing information.
