Vendor Lock vs Vendor Lock
Henning Sprang seems to have a different view on the concept of a Vendor LockIn than I do
On his blog The daily laziness: OpenQRM vs. vendor lock in??? , he describes how openQRM Locks into using .. openQRM.
Well, not really .. at least not in my opinion, although openQRM still has a long way to go and the proposals for a meaner and leaner Henning gives are certainly valid,
openQRM however does not force you to do anything you don't like. The source is available and free, you can modify its behaviour , you yourselve can spend time on in, learn and modify the platform no one .
(given the complexity I agree you won't dive into it in just 5 minutes but you nothing (b)locks you)
Certainly in the virtualization field openQRM gives you the freedom to migrate your machines from one virtualization technology to another, Today VMWare, tomorrow KVM, the week after Xen
or all 3 or them from one management console (can come handy after a merger) all with the same interface. None of the commercial products out there will even think about giving you a GUI to manage their competition.
On top of that when you go out and buy VMWare , you can only manage VMWare instances and you get a framework that will also force you to work in a way you can't change. You have only one company to talk to, VMWare, (maybe via its integrators but they can't fix issues , they don't have the source) with openQRM you can hire other people besides Qlusters , you can change to another organisation to support you.
Try that with VMWare , I fear you are Locked In
