. The prices listed are based on the
Region in which your instance is running. For a detailed comparison
between On-Demand Instances, Reserved Instances and Spot Instances,
see Amazon EC2 Instance Purchasing
Options
.

On-Demand Instances #

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 to Windows Server® 2003 R2, 2008 and 2008 R2). 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 Linux and 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. Each partial
instance-hour consumed will be billed as a full hour.

Reserved Instances #

Reserved Instances give you the option to make a low, one-time
payment for each instance you want to reserve and in turn receive a significant discount on the hourly usage charge for that instance.
After the one-time payment for an instance, that instance is
reserved for you, and you have no further obligation; you may choose
to run that instance for the discounted usage rate for the duration
of your term, or when you do not use the instance, you will not pay
usage charges on it. In addition to Reserved Instances for
Linux/UNIX and Windows operating systems specified below, we also
offer Reserved Instances for Amazon EC2 running SUSE
Linux Enterprise Server
and Amazon EC2
running Microsoft SQL Server.

Dedicated Reserved Instances are
also available.

Reserved Instances can be purchased for 1 or 3 year terms, and the
one-time fee per instance is non-refundable. Usage pricing is per
instance-hour consumed. Instance-hours are billed for the time that
instances are in a running state; if you do not run the instance in
an hour, there is zero usage charge. Partial instance-hours consumed
are billed as full hours.

If Microsoft chooses to increase the license fees that it charges
for Windows, we may correspondingly increase the per-hour usage rate
for previously purchased Reserved Instances with Windows. The
initial one-time payment for a Reserved Instance will be unaffected
in this situation. Any such changes would be made between Dec 1 – Jan 31, and with at least 30 days’ notice. If the per-hour usage
rate does increase, you may continue to use your Reserved Instance
with Windows with the new per-hour usage rate, convert your Reserved
Instance with Windows to a Reserved Instance with Linux, or request
a pro rata refund of the upfront fee you paid for the Reserved
Instance with Windows.

Reserved Instances are available for Linux/UNIX, Windows and SUSE
Linux Enterprise operating systems. You can also optionally reserve
instances in Amazon VPC at the same prices as shown
above. Click here to learn
more about Reserved Instances.

Spot Instances #

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).

Spot Instances. For information on how to get

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
.

If you would like to go straight to a view of the latest Spot Instance pricing:

  1. Log in to the AWS Management Console, then click the “Amazon EC2” tab.
  2. Click on “Spot Requests” in the navigation pane on the left.
  3. Click on “Pricing History” to open a view of pricing selectable by instance type.

Data Transfer** #

The pricing below is based on data transferred “in” and
“out” of Amazon EC2.

Amazon CloudWatch #

Detailed Monitoring for Amazon EC2 is charged at standard Amazon CloudWatch rates of $0.50 per metric per month. Each instance includes seven metrics for total charges of $3.50 per month. Partial months are charged on an hourly pro rata basis, at approximately $0.005/instance-hour.

Note: This new pricing for Detailed Monitoring (representing a 68% decrease from the current price) takes effect starting June 1, 2011. Prior to that, the price remains $0.015 per instance-hour or partial hour. Pricing for Amazon CloudWatch Custom Metrics takes effect starting June 1, 2011. Custom metrics (that you send and Amazon CloudWatch monitors) before that time are free of charge.

Auto Scaling #

Auto Scaling is enabled by Amazon CloudWatch and carries no
additional fees. Each instance launched by Auto Scaling is
automatically enabled for monitoring and the
applicable Amazon Cloudwatch charges will
be applied.

AWS GovCloud Region #

AWS GovCloud is an AWS Region designed to allow U.S. government agencies and contractors to move more sensitive workloads into the cloud by addressing their specific regulatory and compliance requirements. For pricing and more information on the new AWS GovCloud Region, please visit the AWS GovCloud Web Page.

_* Your usage for the free tier is calculated each month across all regions except the AWS GovCloud Region, and automatically applied to your bill – unused monthly usage will not roll over. Does not include Amazon EC2 running Microsoft, Amazon EC2 running SUSE Linux Enterprise Server, Amazon EC2 running IBM, and the AWS GovCloud Region. See offer terms for more details and other restrictions.
** As part of AWS’s Free Usage Tier, new AWS customers will receive free 15 GB of data transfer out each month aggregated across all AWS services for one year except in the AWS GovCloud Region.
*** Rate tiers take into account your aggregate Data Transfer Out usage across Amazon EC2, Amazon S3, Amazon RDS, Amazon SimpleDB, Amazon SQS, Amazon SNS, and Amazon VPC.
