On-Demand Instances let you pay for compute capacity by the hour with no long-term commitments. This frees you from the costs and complexities of planning, purchasing, and maintaining hardware and transforms what are commonly large fixed costs into much smaller variable costs.

The pricing below includes the cost to run private and public AMIs on the specified operating system (“Windows Usage” prices apply toWindows Server 2003 R2, 2008, 2008 R2 and 2012). Amazon also provides you with additional instances for Amazon EC2 running Microsoft Windows with SQL Server, Amazon EC2 running SUSE Linux Enterprise Server, Amazon EC2 running Red Hat Enterprise Linuxand Amazon EC2 running IBM that are priced differently.

Pricing is per instance-hour consumed for each instance, from the time an instance is launched until it is terminated or stopped. Each partial instance-hour consumed will be billed as a full hour.

Reserved Instances provide you with a significant discount (up to 75%) compared to On-Demand Instance pricing. In addition, Reserved Instances provide you with a capacity reservation, so you can have confidence that you will be able to launch the instances you have reserved when you need them.

You can choose between three payment options when you purchase a Reserved Instance. With the All Upfront option, you pay for the entire Reserved Instance with one upfront payment. This option provides you with the largest discount compared to On-Demand Instance pricing. With the Partial Upfront option, you make a low upfront payment and are then charged a discounted hourly rate for the instance for the duration of the Reserved Instance term. The No Upfront option does not require any upfront payment and provides a discounted hourly rate for the duration of the term.

If your needs change after you have purchased a Reserved Instance, you can request to move your Reserved Instance to another Availability Zone within the same region, change its Network Platform or, for Linux/UNIX RIs, modify the instance type of your reservation to another type in the same instance family, at no additional cost.

*This is the average monthly payment over the course of the RI term. For each month, the actual monthly payment will equal the actual number of hours in that month multiplied by the hourly usage rate. The hourly usage rate is equivalent to the total average monthly payments over the term of the RI divided by the total number of hours (based on a 365 day year) over the term of the RI.

**Effective hourly pricing is shown to help you calculate the amount of money that a Reserved Instance will save you over On-Demand pricing. When you purchase a Reserved Instance, you are billed for every hour during the entire Reserved Instance term that you select, regardless of whether the instance is running or not. The effective hourly price shows the amortized hourly cost of the instance (this takes the total cost of the Reserved Instance over the entire term, including any upfront payment, and spreads it out over each hour of the Reserved Instance term).

If you purchase a large amount of Reserved Instances in an AWS region, you will automatically receive discounts on your upfront fees and hourly fees for future purchases of Reserved Instances in that AWS region. Reserved Instance Tiers are determined based on the List Value (non-discounted total price) for the active Reserved Instances you have per AWS region. A complete list of the Reserved Instance Tiers is shown below:

For example, as soon as you have aggregated active Reserved Instances with a List Value totaling more than $500,000 in a single AWS region, you will automatically receive a 5% discount on both upfront and hourly fees for all future Reserved Instance purchases in that AWS region, and those discounts will continue to apply to new Reserved Instances as long as you continue to qualify for the discount tier. For an in-depth example, please visit the EC2 Reserved Instances FAQ.

Please note that Reserved Instance purchases of Windows with SQL Server are not included in the computation of volume tier discounts. Also, due to the scale of Microsoft licensing fees, volume tier discounts are not available for Windows with SQL Server Reserved Instances. Reserved Instance Marketplace purchases do not qualify for the volume discount but the prorated remaining list value for these purchases will count towards your volume discount status.

Spot Instances enable you to bid for unused Amazon EC2 capacity. Instances are charged the Spot Price, which is set by Amazon EC2 and fluctuates periodically depending on the supply of and demand for Spot Instance capacity. To use Spot Instances, you place a Spot Instance request, specifying the instance type, the Availability Zone desired, the number of Spot Instances you want to run, and the maximum price you are willing to pay per instance hour. To determine how that maximum price compares to past Spot Prices, the Spot Price history is available via the Amazon EC2 API and the AWS Management Console. If your maximum price bid exceeds the current Spot Price, your request is fulfilled and your instances will run until either you choose to terminate them or the Spot Price increases above your maximum price (whichever is sooner).

The following table displays the Lowest Spot Price per Region and instance type (updated every 5 minutes). In addition to Linux/Unix and Windows, we also offer Spot Instances for Amazon EC2 running SUSE Linux Enterprise Server.

The pricing below is based on data transferred "in" to and "out" of Amazon EC2. 

Rate tiers take into account your aggregate usage for Data Transfer Out to the Internet across Amazon EC2, Amazon S3, Amazon Glacier, Amazon RDS, Amazon Redshift, Amazon SES, Amazon SimpleDB, Amazon SQS, Amazon SNS, Amazon DynamoDB, AWS Storage Gateway, and Amazon CloudWatch Logs.

Data transferred “in” to and “out” of Amazon EC2, Amazon RDS, Amazon Redshift and Amazon ElastiCache instances or Elastic Network Interfaces across VPC peering connections in the same AWS Region is charged at $0.01/GB.

Data transferred "in" to and "out" of Amazon Elastic Load Balancing is priced equivalent to Amazon EC2. Data processed by Amazon Elastic Load Balancing will incur charges in addition to Amazon EC2 data transfer charges.

EBS-optimized instances enable EC2 instances to fully use the IOPS provisioned on an EBS volume. EBS-optimized instances deliver dedicated throughput between Amazon EC2 and Amazon EBS, with options between 500 and 4,000 Megabits per second (Mbps) depending on the instance type used. The dedicated throughput minimizes contention between Amazon EBS I/O and other traffic from your EC2 instance, providing the best performance for your EBS volumes. EBS-optimized instances are designed for use with both Standard and Provisioned IOPS Amazon EBS volumes. When attached to EBS-optimized instances, Provisioned IOPS volumes can achieve single digit millisecond latencies and are designed to deliver within 10% of the provisioned IOPS performance 99.9% of the time. Pricing for supported instance types is listed below. For C4 instance types, EBS-optimization is enabled by default at no additional cost. 

The hourly price for EBS-Optimized instances is in addition to the hourly usage fee for supported instance types.

Provisioned IOPS (SSD) is charged by the amount you provision in IOPS (input/output operations per second) X the percentage of days you provision for the month. For example, if you provision a volume with 1000 IOPS, and keep this volume for 15 days in a 30 day month, then in a Region that charges $0.10 per provisioned IOPS-month, you would be charged $50 for the IOPS that you provision ($0.10 per provisioned IOPS-month * 1000 IOPS provisioned * 15 days/30).

Amazon EBS currently supports up to 4000 IOPS per Provisioned IOPS (SSD) volume. For a given allocation of resources, the IOPS rate you get from your Provisioned IOPS (SSD) volume depends on the I/O size of your applications’ reads and writes. Provisioned IOPS (SSD) volumes process your applications’ reads and writes in I/O sizes of 16KB or less. Every increase in I/O size above 16KB will linearly increase the resources you need to achieve the same IOPS rate. For example, if you have provisioned a volume with 2000 IOPS, that means that it can handle 2000 16KB writes per second, or 1000 32KB writes per second, or 500 64KB writes per second, and so on. You can use Amazon CloudWatch to monitor your throughput and I/O sizes.

You can have one Elastic IP (EIP) address associated with a running instance at no charge. If you associate additional EIPs with that instance, you will be charged for each additional EIP associated with that instance per hour on a pro rata basis. Additional EIPs are only available in Amazon VPC.

To ensure efficient use of Elastic IP addresses, we impose a small hourly charge when these IP addresses are not associated with a running instance or when they are associated with a stopped instance or unattached network interface.
