inspiring Per-Second Billing from aws






When Amazon Web Services (aws)  launced Amazon Elastic Compute Cloud (EC2) in 2006,  The pay-as-you-go model inspired aws customers to think about new ways to develop, test, and run applications of all types.
Now aws is introducing Per-Second Billing for EC2 and Amazon Elastic Block Store (EBS).

Effective October 2nd, usage of Linux instances that are launched in On-Demand, Reserved, and Spot form will be billed in one-second increments. Similarly, provisioned storage for EBS volumes will be billed in one-second increments.
Per-second billing also applies to several other services like aws EMR, aws Batch, Elastic GPUs, Provisioned IOPS.
This change is effective in all aws regions and will be effective October 2, for all Linux instances that are newly launched or already running. There is a 1 minute minimum charge per-instance.
Per-second billing is not currently applicable to instances running Microsoft Windows or Linux distributions that have a separate hourly charge. 
Aws points out that "One of the many advantages of cloud computing is the elastic nature of provisioning or deprovisioning resources as you need them. By billing usage down to the second we will enable customers to level up their elasticity, save money, and customers will be positioned to take advantage of continuing advances in computing."
