This question addresses the essential difference between ENKI and all other service providers today.  ENKI does not lease servers: we are a utility computing service provider.  If you're familiar with Amazon EC2, our service is similar - but much more reliable (see the related blog article ).  We charge on resources used per month, similar to your utility bill.  Our costing model for computing and hence our pricing model is based on the percentage of a standard 16GB/4 core server that you use, whether that's CPU or RAM.  This is how the number ends up being expressed in mb/mo (for processor time it is per percent per month).  This is generally in your interest and saves you money.  For example, every customer we've signed so far has come to us wanting to lease an equivalent hardware configuration to the one they currently have.  However, each of these customers ended up using significantly less resources than the total in their pre-existing hardware, while getting equal or better performance.  The reason for this is that when you buy or lease hardware, you have to provision the absolute maximum you could possibly need over the life of the equipment to serve peak loads.  When you buy utility computing services, you pay for what you use, and if you need more, you request it and it's almost instantly available.  In addition, this means that you can provision virtual private data centers of varying sizes any time you want, and destroy them again when you want, and only pay for what you used.  This allows some of our customers to create large demo configurations and then effectively get rid of the hardware they used for the demos when they are done.  If by some chance you end up using all the resources on a full server, our prices are competitive with leasing the servers in a colocated environment with support and installing AppLogic on them yourself.

Do you have a document explaining how you bill for resources consumed?
