There was an amount of kerfuffle when VMware released vSphere v5.0 and moved to a memory centric licensing model. We speculated on whether other vendors would follow suit. Microsoft has unveiled Windows 2012 licensing terms, which it claims make licensing simpler and better value . The thing to commit to memory? There are now only four versions, and licensing is processor and client access license based.
Windows 2012 Licensing … Editions
Microsoft has aimed to make things far simpler with Windows 2012. Functionality differences between Datacenter/Standard editions are gone – the Enterprise edition no longer exists.
*CALs are required for every user or device accessing a server directly or indirectly. See theProduct Use RightsÂ for details.
With Windows 2012 Datacenter Microsoft has consolidated the two licenses into one and left the price at $4,809. Unlimited virtualisation licensing. Thus, if you buy one copy of Datacenter for a dual CPU host (any virtualisation) you get unlimited installations of Windows Server 2012 or lower (any edition) for unlimited VMs on that host.
Windows 2012 Standard Edition has had a cost increase – however while the number of virtual instances you can support remains the same (it’s 2) – Windows 2012 Standard Edition has the same product features as datacentre – and supports up to 640 processors and 4TB memory.
If you’ve purchased Microsoft’s Software Assurance then Enterprise Edition becomes two Windows 2012 Standard… remember – Standard Edition has the fullÂ product feature set – including clustering.
Client Access Licenses (CALs)
Nothing to see here.Â Just continue to license clients for the highest version of Windows Server that they use. RDS CAL licensing is not changing either.Â Anyone running either Web (only) or HPC workloads (only) on their servers do not require CALs.
Neither Window Server 2012 Essentials or Windows Server 2012 Foundation require CALs.
Simpler, Better Value?
Perhaps with the release of 2012, Microsoft have a rare moment ofÂ being a vendor that made a change to product licensing without upsetting someone. Although there’s always time: some organisations might be disgruntled with the increased price of Standard Edition despite the increase in features, and some home users may look forlornly at the demise of Home Server or maybe they’ll be excited at the prospect of change.
Because, it is fair to say that Microsoft have made licensing in your data centre more straightforward. Windows 2012 comes in Standard or Datacenter. They are licensed by processor and CALs. They both come with all the scalability and all the features including Hyper-V. Indeed, there is still a free Hyper-V Server 2012 that can be used for VDI environments, or Linux VMs.
Memory licensing? <shudders>
For more detailed information you can view Microsoft’s release information,Â where they have a Licensing and Pricing FAQ. I’d also recommend a visit to Aidan Finn’s analysis ofÂ Windows Server 2012 Licensing In Detail.
