What does it mean for an operating system to be "supported"?

All supported operating systems have a "template" in CenturyLink Cloud that is created, maintained, and managed by CenturyLink Cloud engineers. Templates can be viewed in the "Create Server" screen and accessed via the API. These templates are the basis for all new virtual machines created in the platform.

Can I build custom templates?

Yes - the only requirement is that each custom template needs to "map" to a supported OS template. For best practices, read this article: "How To: Create Customer Specific OS Templates"

What is your operating system retirement policy?

This is listed here.

Can I perform an in-place upgrade of the Operating System?

No, in-place upgrades of the Operating System are not supported. This means that you cannot, for example, upgrade a Windows Server 2012 Standard edition to Windows Server 2012 Datacenter edition. It will be necessary to deploy a new server if you need a different OS edition.

I'd like to deploy an operating system that is not supported. What are my options?

We do not recommend that you deploy unsupported operating systems in the platform. CenturyLink Cloud SLAs will not apply to virtual machines running an unsupported OS. In addition, some features may not work on unsupported OSes. Your options are to request a new OS be supported using our suggested feature process, or to deploy the OS in a traditional hosting environment.
