I challenge you to point out any major difference between a Private Cloud and provisioning servers with VMWare or Xen etc. You have no platform elasticity for scaling, you're still using the same big iron as before. Your redundancy still comes down to having the same exact SAN hardware and geographic datacenters. So what exactly is changing and where does the Cloud part come in.
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model is composed of five essential characteristics, three service models, and four deployment models.

So unless you believe that NIST is a marketing organization well, then there is a standard, technical definition of what Cloud Computing is.NIST Computer Security Publications - NIST Special Publications (SPs) Here is a summary of their definition:
Resource pooling: Departments that have spurts of processing utilization can now take chunks out of the available resources as they need it. So if your finance depart only needs a certain amount of computing resources for a week during quarter close, then they can get it on demand and those resources can then be returned automatically to the shared pool. This is a very different model where in the standard model finance usually has its resources allocated statically and continue to cost the company money even when not in use.
Rapid elasticity: This goes along with resource pooling in that if demand on a resource increases it should not fail, but scale automatically to handle the increased demand. For many services it will appear to the consumer that resources are unlimited and can be apportioned in any quantity at any time.
Measured service: Here is where we see a big shift for IT departments. Instead of acting as a black hole into which money is thrown, IT departments can now report out on a service basis what each department is using, how they are using it and what it costs.
Now let me attack your complain that we are still using the same big hardware as before, that we are still limited by the same SAN and geographically confined datacenter. If you are still doing things the same way as you did in the past, but just using virtualization, then you are by definition not doing private cloud. If your developers are not able to go to a self service portal to provision their own systems but instead have to go through a drawn out process to have someone on the ops team build them servers and purchase licensing, then you are not doing private cloud. I'm not saying everything has to be self-service and scripted/automated. But that most of it is that way is the point of it.
So the idea that QA and Finance (who are resource hungry but only in spurts) can do much more because it actually costs them less since they are not purchasing all their resource in a dedicated model now. I don't need two dedicated servers with 32 GB RAM and a massive amount of storage to process their cube/ETL. I just have a smaller machine running the cube in production and then when closing week comes, a new system is scripted to come online that hooks into the ETL system, someone on the Finance team pushed the button saying the books are closed and boom! The job gets started and when it's all finished the extra system for ETL disappears, I never had to touch it, and the amount of RAM used on the production server running the cube drops off, everyone gets their stuff.

pram wrote: » How can a private cloud be elastic? Will each corporation simply purchase spare hardware? What happens if you exceed the hardware you have sitting in your datacenter? Are companies that are averse to large hardware purchases suddenly be willing to buy spare capacity simply because its now a Private Cloud? Doesn't sound very elastic IMO. If you shut down containers you're still paying for the hardware, electricity, etc etc.

If they do get out of servers, I'd have to think open source platform certifications (e.g. RedHat, Cloudera) would start taking on more prominence. What do y'all think?
