RE: cloud services with new development on IBM i on Power

Nice fictitious numbers. You'd be good at marketing :-)

You can do it without 10 virtual machines, same way you describe on the IBM i. Create separate schema's, library lists (aka databases) on platform X,Y, or Z.

I don't see any cost savings here.

Richard Schoen makes a valid point.  Cheap and easy for someone to
begin programming on Windows/Linux/Apple.

Microsoft's empire was built on instant gratification. I must agree that it works. But I'd like more people to think strategically rather than tactically. If you're hosting broadly scoped application & database environments for say 10 separate tenants using Rackspace (.Net, JEE, PHP), you do it with at least 10 virtual machine instances, perhaps more. At least that't the type of configuration in every case that I'm aware of.

It appears that Rackspace charges apx. $500 - $1,000 per month for VM instances that support both App Server and Database workloads. I would proposed hosting say 10 tenants, 2K-3K users on a 4-core Power 720. Say 64GB RAM. Say 1TB DASD. Use IBM i Subsystems and Library Lists to partition the workloads. Drop your hosting costs from $5K-10K per month to something like $1K per month.
