Previously, the Amazon CloudFront Premium flat-rate plan supported a single usage allowance, and customers who outgrew it needed to contact us to discuss custom pricing options. Now, the Premium plan offers a range of self-service monthly usage levels ranging from 500 million to 6 billion requests and 50 TB to 600 TB, so customers can scale within the plan as their applications grow. Enterprises and mid-sized businesses whose baseline traffic previously made them ineligible for flat-rate plans can now adopt the Premium plan at a usage level that fits their application.
