I don't trust the cloud, plain and simple. We're putting our data on their hardware, but how do we know their hardware is safe? How do we know their services will be available $\frac{24}{7}$ like we need?

You:

Cloud providers employ a variety of techniques to ensure their services are available nearly all the time. Some of the biggest providers guarantee their services are available $99\mathrm{.}99\%$ of the time or better. We can do some research to choose one or more providers that will give us the reliability we need.
