Understanding different types of compute
When we architect solutions, there will often be at least one component that needs to host, or run, an application. The application could be built specifically for the task or an off-the-shelf package bought from a vendor.
Azure provides several compute services for hosting your application; each type can be grouped into one of three kinds of hosting model:
