EC2 Pricing

• If you have an ELB running, that also incurs costs depending how much time it runs for and how much data it processes.

• Per second billing for Linux (after the first 60 seconds).

• Per hour billing for all other OSs.

EC2 Pricing depends on:

• Clock hours of server time: Resources incur charges when they are running.

• Instance type: Amazon EC2 provides a wide selection of instance types optimized to fit different use cases. Better instance = more expensive.

• Pricing model: On-demand, reserved, spot or dedicated.

• Number of instances: You can provision multiple instances of your Amazon EC2 and Amazon EBS resources to handle peak loads.

• Transfer of data between Regions.

• Load balancing: The number of hours the Elastic Load Balancer runs and the amount of data it processes contribute to the monthly cost.

• Detailed monitoring: For a fixed monthly rate, you can opt for detailed monitoring, which includes seven preselected metrics recorded once a minute.

• Auto Scaling: Auto Scaling automatically adjusts the number of Amazon EC2 instances in your deployment according to conditions you define.

• Elastic IP addresses: You can have one Elastic IP (EIP) address associated with a running instance at no charge. Charged if they are not attached to instances or NAT gateways.

• Operating systems and software packages: Operating system prices are included in instance prices, unless you choose to bring your own licenses.
