Public Cloud Requirements
You can run SUSE Manager Server on a public cloud instance from a third-party provider such as Amazon EC2, or Microsoft Azure.
This section details the requirements for using SUSE Manager on a public cloud instance.
Public clouds provide SUSE Manager under a Bring Your Own Subscription (BYOS) model. This means that you must have SUSE product entitlements to use SUSE Manager. For more information about public cloud entitlements, see installation:pubcloud-setup.adoc.
Depending on the public cloud framework you are using, you can locate the SUSE Manager images by searching for the keywords
Select a public cloud instance type that meets the hardware requirements in installation:hardware-requirements.adoc.
Before you begin, here are some other considerations:
The SUSE Manager setup procedure performs a forward-confirmed reverse DNS lookup. This must succeed in order for the setup procedure to complete and for SUSE Manager to operate as expected. It is important to perform hostname and IP configuration before you set up SUSE Manager.
SUSE Manager Server and Proxy instances need to run in a network configuration that provides you control over DNS entries, but cannot be accessed from the internet at large.
Within this network configuration DNS resolution must be provided:
hostname -fmust return the fully qualified domain name (FQDN).
DNS resolution is also important for connecting clients.
DNS is dependent on the cloud framework you choose. Refer to the cloud provider documentation for detailed instructions.
We recommend that you locate software repositories, the server database, and the proxy squid cache on an external virtual disk. This prevents data loss if the instance is unexpectedly terminated. This section includes instructions for setting up an external virtual disk.
If you are attempting to bootstrap traditional clients, check that you can resolve the host name of the server while you are logged in to the client.
You might need to add the FQDN of the server to
When you use SUSE Manager on a public cloud, you must use a restricted network. We recommend using a VPC private subnet with an appropriate firewall setting. Only machines in your specified IP ranges must be able to access the instance.
When you run SUSE Manager on public clouds, you must apply security measures to limit access to the instance. A world-accessible SUSE Manager instance violates the terms of the SUSE Manager EULA, and is not supported by SUSE.
To access the SUSE Manager Web UI, allow HTTPS when configuring the network access controls.
Separate Storage Volumes
We recommend that the repositories and the database for SUSE Manager are stored on separate storage devices to the root volume. This will help to avoid data loss. Do not use logical volume management (LVM) for public cloud installations.
You must set up the storage devices before you run the YaST SUSE Manager setup procedure.
Provision your disk devices in the public cloud environment, according the cloud provider’s documentation. The size of the disk for repositories storage is dependent on the number of distributions and channels you intend to manage with SUSE Manager. When you attach the virtual disks, they will appear in your instance as Unix device nodes. The names of the device nodes will vary depending on your provider, and the instance type selected.
