We are leasing hardware, and we are leasing a lot of OVH (in addition to a number of smaller providers). OVH does a good job, and if you build your infrastructure to load-balance around failure (which does not happen often), you'll hardly notice it. Often we get an email from OVH telling us that support techs have been automatically dispatched to a node which we hadn't even alerted about yet. Docker is basically a miracle drug for this kind of thing. Our hardware costs are less than half of what they were with EC2. Huge savings.
