re: Private Cloud Wars: OS Wars, The Sequel
I see what you're saying about the difficulties of putting these into categories. Unfortunately, I don't think CloudPlatform fits that well with the Apple analogy. While it's true that it's product, rather than project, focused & "just works," there are number of hardware vendors that would not agree with assessment that it's Citrix centric including folks like Cisco, ALU & SolidFire to name a few on the hardware side. On the software side, I've seen a huge spike in software integrations in the last 12 months. That's where the analogy also falls apart -it's not part of a closed ecosystem like Apple has created. If you had to peg an OS - I'd actually liken it Linux, and in particular, Red Hat. CloudPlatform is like RHEL. A number of folks use CentOS and Fedora - those line up closer to Apache CloudStack. Perhaps another analogy to explore is Android, but the Open Source side outside of Google, is VERY geek focused rather than IT focused so it's not a perfect analogy/comparison either..
Need to correct - CloudPlatform is not an Open Core model; that's Eucalyptus.
CloudPlatform is the commercially supported version of Apache CloudStack & includes best in breed VMware support. A majority of the enterprise customers I know of are running ESXi as their hypervisor of choice & they don't pay a dime more for that support. Granted, VMware support is not as interesting for SPs though a number do run VMware and are not VMware Service Providers (VSPPs.) The fact that the product focuses on two different unique workloads - the traditional, HA enabled enterprise workload as well as the AWS/OpenStack style workload is a huge differentiator. While enterprises talk about wanting to move to cloud, it will take a number of years. Supporting both the legacy & the new has been a critical concern that resonates well with enterprise buyers. It's part of the reason why there are a number of paying CloudPlatform customers.
Lastly, on the Open Source side, I know of a number of big names that use Apache CloudStack & do not have a commercial relationship with Citrix. It is growing and active community outside of the commercial side of the equation.
