Buy some expertise. Even true believers don't have all of the answers. Joe Emison, an expert I spoke with for our cloud ROI report, maintains that "anyone who has ever successfully administered a Linux box can stand up a private cloud." But I've seen some very smart people have at least some difficulty getting going.
Maybe that's because there are so many cloud options. Open source? Proprietary? Do you use CloudStack? OpenStack? Eucalyptus? Nimbula? Geez, do you even use a software solution, or do you seek comfort in the expensive but accountable arms of a hardware/software Vblock solution?
You can't possibly go cloud at enterprise scale without a management platform, so which one do you use? Rightscale? Cloudscaling? enStratus? See what I mean?
All of a sudden there are lots of permutations. Spending a few thousand bucks on some outside expertise turns into a bargain compared to hundreds of hours of internal staff R&D.
One thing is clear. The truly successful private cloud implementations are typically using commodity hardware, not highly expensive hardware or hypervisors. As Nishan Sathyanarayan, director of professional services for Nimbula, points out, if you're satisfied with Google, Amazon, and Facebook, then you're satisfied with large-scale infrastructure running open source on commodity equipment.
I am well aware that Cisco and friends have invested heavily in VCE and the Vblock platform. They're trading on their brand names, on the fact that they have earned deep loyalties in the infrastructure world. But cloud is not about name brand infrastructure. Don't listen to your staffers when they tell you that the expertise they need is centered on brand name hardware and hypervisor solutions. It may be one day, but it's not now.
Want the secret sauce recipe? Find folks who know the software side, and who know how to use commodity gear. Get your training and consulting from them, not from the name-brand hardware people who have a vested interest in recapturing your enterprise's infrastructure business.
>> Start small, avoid academic exercises. If you have some cloud-obsessed folks on staff who have spent the time to come up to speed on their own, fine. Implement a small private cloud yourself. But be prepared for staffers to spend more time researching and debugging.
The bottom line is that your IT organization needs to experience a private cloud platform in order to make decisions about operations and maintenance and plan for what the infrastructure--and its staffing--will look like in 24 or 36 months. Even if you need to bring in outside expertise, you can get started for less than $20K.
But make sure that it's not just an academic exercise. Even if your initial private cloud is limited in scope, put it into production. You're going to be living with something like it in the future, so you'd better get used to it now.
