 '''[[w:Google Cloud Platform|Google Cloud Platform]] (GCP)''', offered by Google, is a suite of [[w:cloud computing|cloud computing]] services that runs on the same infrastructure that Google uses internally for its end-user products, such as [[w:Google Search|Google Search]] and [[w:YouTube|YouTube]].

+== Introduction to containers and Docker ==
+A '''[[w:container (virtualization)|container]]''' is an isolated [[w:user space|user space]] in which [[w:computer program|computer program]]s run directly on the host [[w:operating system|operating system]]'s [[w:Kernel (operating system)|kernel]] but have access to a restricted subset of its resources. A computer program running on an ordinary operating system can see all resources (connected devices, files and folders, [[w:Shared resource|network shares]], CPU power, quantifiable hardware capabilities) of that computer. However, programs running inside a container can only see the container's portion of the file system and the devices assigned to it. The mechanism by which a host operating system runs programs in isolated user-space environments is called ''containerization'' or ''operating-system-level virtualization''. (Wikipedia)
