This documentation is for dedicated instances, which help with HIPAA compliance requirements by providing the option of choosing dedicated hardware for your instances.
Most instance types are available as Dedicated instances, to see exactly which please consult the table in this document.
- There is a special per-hour per-region fee for each region in which you have instances running on dedicated hardware. This fee is in addition to the base instance fees and is $2.40/hour for each region in which you have running dedicated instances, regardless of how many dedicated instances you are running.
- If you require HIPAA compliant environments, you must have Premium or Managed Support and also need to enter into a Business Associates Agreement. Submit a ticket to get started with HIPAA compliance documentation.

Configure dedicated instances
Important: There is a special per-hour per-region fee for each region in which you have instances running on dedicated hardware. This fee is in addition to the base instance fees and is $2.40/hour for each region in which you have running dedicated instances, regardless of how many dedicated instances you are running.
You can configure dedicated instances when you add new instances to a new or existing environment.
Note: We recommend testing in a staging environment before applying changes in a production environment.
To add a new dedicated instance
Ensure that you meet all the prerequisites above.
Add an instance in the usual way.
See the database docs for more information about adding a database instance to an environment.
Select the appropriate dedicated instance size, which appears with the added "[Dedicated]" in the instance size description.
Click Add to Cluster (or Boot This Configuration, if you are re-booting an existing environment).
See the related documentation for more information on adding instances to your environment.
Note: If you are adding a dedicated database instance, you also need to click Apply to update the database.yml file.
Verify dedicated instances
Note: When you are testing in staging, consider the differences between your test and production loads.
To verify dedicated instances
Ensure that instance provisioning worked and the instance is running.
In general, that is enough of an indication that the dedicated instance is working fine.
- Review the Troubleshooting tips below for more information.
- If this is a staging environment and you are finished with testing, be sure and stop any dedicated instances to avoid unnecessary charges.
- Stop any unneeded dedicated instances to avoid unnecessary charges.
You might have these questions about dedicated instances.
Why is the cost of dedicated instances higher than the same instance type, non-dedicated?
Your dedicated instances are reserved exclusively for your app and are your own hardware, within your own Amazon Virtual Private Cloud (VPC).
But I thought all Engine Yard instances were dedicated to my applications' use?
This is terminology chosen by AWS to indicate that the instance you are provisioning ("dedicated instance") is on its own hardware. All Engine Yard provisioned instances are virtual machines that are dedicated to your use only; they are virtual machines and as such may be sharing the same a physical server (hardware) with other virtual machines. AWS dedicated instances mean dedicated hardware.
How secure is it?
Your dedicated instances are contained within a private, isolated virtual network, and are isolated at the hardware level. It is your own non-shared server.
How much does it cost?
There is a $2.40/hour fee for using dedicated instances in each region they are used in, regardless of how many instances are used. Aside from that, dedicated instance hourly rates are the same as non-dedicated instance hourly rates.

|No dedicated instances appear in the add-instance drop-down selection list.||If you have had an Engine Yard account for a while, you might need to create a custom VPC in order to use the dedicated instances feature in your region. This is because it is part of the AWS VPC feature set. Please contact Support for assistance.|
|The dedicated instance will not provision in any AZ in the region I selected.||Same solution as above.|
|When I clicked HTTP on the app server, I received a 500 Internal Server Error.||If this is the first time provisioning, wait a few minutes and try again.|
