"You can run your Docker containers across entire data centers without ever creating a "cluster" as other IaaS providers would have you do."
This is a little unclear. I get that you don't have to create a "cluster" because you're going to use the API to launch containers on existing dedicated hardware, but how is that a WIN for your finance team? I guess I'm missing something.. but wouldn't you have to already have systems online that you're paying for that these containers can be launched on?
Is it multi-tenancy of various Joyent customers on the same hardware? So you get containers placed somewhere in their data center on shared hardware with other customers? Or do you already need to have dedicated hardware provisioned at Joyent to launch containers on? I'm still unclear on that point, which makes me question how it's saving the end user money.
Yes, you are running on shared hardware, securely, but with no hypervisor.
The biggest money-saver is in performance. IO-heavy applications can see anywhere from 5-10x performance improvements[1] by switching from hardware- to OS-virtualization.
Yes, the the containers are running on bare-metal multi tenant hardware. Some of the savings comes from the performance gains as noted elsewhere, but additional savings comes from not having to pay for and manage an additional layer of virtual machines.
There's no need to provision anything other than the containers.
