AWS Marketplace Metering Service is now available in the US East (Ohio), Canada (Central), and EU (London) regions. AWS Marketplace Metering Service enables customers to purchase software from select AWS Marketplace vendors that price by the usage within an Amazon Machine Image (AMI), rather than a flat hourly, monthly, or annual fee for running the AMI. These pricing dimensions better enable customers to pay for only what they need when running software projects. As with other AWS Marketplace products, usage is aggregated at the end of the month, along with other AWS products, and charged as part of an existing AWS bill.
