problem that developers can only operate on a single operating system is that it inevitably leads to a proliferation of Windows. In other words, Windows gave birth to Windows. There's no way to break this cycle.On the other hand, *nix developers are usually familiar with multiple operating systems (linux,unix,osx,windows, etc.), the internal workings of an operating system, different distributions (based on Debian and Fedora based), window manager, Desktop Manager, file system, package manageme

labels, which define the deployment specification for your application.

The operating system must have application software, so as to serve the end user, application software is really landed business, so that there will be users, with users, the entire system is running. This is what the engineers say about the stack, the IaaS, PaaS, SaaS three tiers we hear. The IaaS layer is like a PC's base hardware plus driver, and the PAAs layer is like an operating system on a PC-
