== Pricing ==

There are different types of EC2 instances, at different price points. The cheapest is '''On Demand''', which can be created and destroyed as needed. '''Reserved''' EC2 instances can be purchased for either 1 or 3 year periods at significant savings compared to On Demand instances.

A new On Demand EC2 is created [[Hosting_A_PHP_Web_Application_On_AWS|when a new Elastic Beanstalk environment is created]]. In order to bill that EBS instance as Reserved, purchase a Reserved EC2 instance that matches both the Server Type (e.g. t2.nano, t2.micro, etc.) and the region of the EC2 instance created for the EBS. As long as there is a reserved EC2 instance that matches the instances that have been created for the EBS environments, those EC2 instances will be billed at the reserved rates. <ref>[https://forums.aws.amazon.com/message.jspa?messageID=232310#232310 Converting from On Demand to Reserved Instances] - AWS Developer Forums</ref>
