Use discount cloud instances. Just as they offer storage tiers at different price points, most cloud providers also allow users to run virtual servers at discounted prices under certain conditions.

The catch is that the availability of these types of instances is not guaranteed. They are thus not a good fit for workloads that need to run constantly, such as with the hosting of a web app.
