AWS Premium support will facilitate resolution with Red Hat support for any issues that require escalation. AWS customers using RHEL will not contact Red Hat directly unless they have purchased EC2 through Red Hat Cloud Access and have a direct support agreement with Red Hat.
Q. How are the base Amazon Machine Images and running instances maintained?
Red Hat maintains the base Red Hat Enterprise Linux AMIs for Amazon EC2. All instances of Red Hat Enterprise Linux on Amazon EC2 will receive updates at the same time that updates are made available from Red Hat. Updates can also be installed using standard Red Hat Enterprise Linux systems management tools. To be notified when updates are available, subscribe to Red Hat Security Announcements.
Q. How do I launch an instance of Red Hat Enterprise Linux on Amazon EC2?
To get started, sign-in to the AWS Management Console, select the Amazon EC2 dashboard, click on the Launch Instance button and choose Red Hat Enterprise Linux from the Instance Wizard. Alternatively, you can launch from AWS Marketplace via 1-Click or from the AMI IDs directly. View a matrix of all Red Hat Enterprise Linux AMI IDs is listed here.
Q. Is auto-scaling available for Red Hat Enterprise Linux on Amazon EC2?
Q. Are there any restrictions on the instance types supported for Red Hat Enterprise Linux on Amazon EC2?
Red Hat Enterprise Linux on Amazon EC2 is available for all instance types in all regions.
Q. Are there any differences in the underlying Red Hat Enterprise Linux configurations depending on instance type?
There are three types of Red Hat Enterprise Linux AMIs available, 32-bit, 64-bit and Hardware Virtualization Machine (HVM). Depending on which instance type you are running, the appropriate AMI will be provisioned.
Q. How do I purchase and launch a Reserved Instance?
You can purchase Reserved Instances (RI) through the AWS Management Console or using EC2 API tools. In the AWS Management Console, simply click the “Reserved Instances” button in the EC2 Instances section, and select “Purchase Reserved Instances”. The wizard will walk you through the purchase. Using the API tools, you can list the available Reserved Instances for purchase with the DescribeReservedInstancesOfferings API method. You can then purchase an EC2 Reserved Instance by calling the PurchaseReservedInstancesOffering method. Launching a Reserved Instance is no different than launching an On-Demand Instance. You simply use the RunInstances command or launch an instance via the AWS Management Console. Amazon EC2 will optimally apply the cheapest rate that you are eligible for in the background.
Q. Where do I find the Red Hat Enterprise Linux Amazon Machine Images (AMIs) once I’ve purchased licenses directly from Red Hat through their Cloud Access license mobility program?
After successfully purchasing from Red Hat, Red Hat Enterprise Linux Cloud Access Amazon Machine Images (AMIs) are shared with your account and show up under “Owned By Me” as Private Images; they can’t be located via a search of public AMIs.
You can now either navigate to the AMI via:
EC2 -> AMIs (left nav) -> Filter: Owned By Me -> Private Images (pulldown selection)
Or, if using the EC2 Launch Instance wizard:
My AMIs (tab) -> Viewing: Private Images (pulldown selection)
Q. How do I get updates and regular patches for Amazon EC2 instances running Red Hat Enterprise Linux?
Red Hat Update Infrastructure (RHUI) is maintained by Red Hat in each AWS region and can be accessed to get regular updates and patches. Red Hat Enterprise Linux instances will have access to the regional repositories to receive incremental updates and is included in all prices.
Q. Can I purchase support directly from Red Hat?
If you desire a direct support relationship with Red Hat, then purchasing your Red Hat Enterprise Linux for Amazon EC2 licenses directly from Red Hat through their Cloud Access program is the best option.
Visit the Red Hat website for more information about Red Hat Cloud Access for AWS.
Q. If I launch Red Hat Enterprise Linux on Amazon EC2 instances in an Amazon Virtual Private Cloud (VPC), how do I access the Red Hat Update Infrastructure (RHUI)?
All on-demand Red Hat Enterprise Linux (RHEL) Amazon Machine Images (AMIs) are configured to utilize the Red Hat Update Infrastructure (RHUI) in AWS. If in a VPC, Amazon EC2 RHEL instances will need to access RHUI in EC2 either through the VPC Internet Gateway, through an attached Virtual IP, or through a VPN or Direct Connect connection to a data center that routes the update request through the general internet to the RHUI servers.
If you would rather get updates from an on-premises update repository, like Red Hat Network Satellite, then you will need to have an account with Red Hat and purchase entitlements to their Cloud Access AMIs through this license mobility program. These entitlements come in the form of the traditional annual subscriptions.
Once deployed using the Cloud Access AMIs, de-register your instance and re-register to your on-premises update infrastructure. Note, however, that in this set up you will incur additional network charges for data transfer out of AWS. Avoiding these network charges is one of the benefits of using the in cloud Red Hat Update Infrastructure.
Steps to de-register and re-register:
- Edit the /etc/yum.repos.d/redhat-rhui-client-config.repo and change 'enabled=1' to 'enabled=0’
- Edit the /etc/yum.repos.d/redhat-rhui.repo and change 'enabled=1' to 'enabled=0’ for all repository entries
- Edit /etc/yum/pluginconf.d/rhnplugin.conf and change 'enabled=0' to 'enabled=1'
- RHN register with rhn_register or rhnreg_ks
Q. Is it possible to migrate existing Red Hat Enterprise Linux images to AWS?
Yes. Red Hat Cloud Access customers can now use VM Import/Export to migrate 64-bit Linux VMs from their VMware, Hyper-V, or Citrix Xen environments to Amazon EC2. For detail on supported instance types and RHEL versions, visit the VM Import User Guide, and the FAQ page.
