One of the most interesting and relatively nascent markets to emerge from the rise of cloud infrastructure is PaaS. While Infrastructure-as-a-Service forces a developer to set up, configure, deploy and manage an application from scratch, a PaaS hides all of this complexity, often allowing a software developer to simply upload application code to run. The platform handles all the gritty details that system administrators usually handle and lets the developer focus on the software. In the non-technical world you could compare this to buying a piece of furniture at IKEA, lugging it home and then figuring out how to put it together, vs. buying it online and having it delivered and set up in your living room.
