== Introduction to containers ==

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)

== Kubernetes ==
'''[[w:Kubernetes|Kubernetes]]''' (commonly stylized as '''k8s''') is an [[w:open-source software|open-source]] [[w:Operating-system-level virtualization|container]] [[w:orchestration (computing)|orchestration]] system for automating [[w:application software|application]] deployment, scaling, and management. It was originally designed by [[w:Google|Google]], and is now maintained by the [[w:Cloud Native Computing Foundation|Cloud Native Computing Foundation]]. It aims to provide a "platform for automating deployment, scaling, and operations of application containers across clusters of hosts". It works with a range of container tools, including [[w:Docker (software)|Docker]]. Many [[w:cloud computing|cloud]] services offer a Kubernetes-based platform or infrastructure as a service ([[w:Platform as a service|PaaS]] or [[w:Infrastructure as a service|IaaS]]) on which Kubernetes can be deployed as a platform-providing service. Many vendors also provide their own branded Kubernetes distributions. (Wikipedia)

== Google Cloud Platform ==

'''[[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]].

== Other useful software and services ==
=== Other software and services by Google ===

'''[[w:Firebase|Firebase]]''' is a [[w:mobile application|mobile]] and [[w:web application|web application]] development platform developed by Firebase, Inc. in 2011, then acquired by Google in 2014. (Wikipedia)

'''[[w:Google Stackdriver|Google Stackdriver]]''' is a [[w:freemium|freemium]], credit card required, [[w:cloud computing|cloud computing]] [[w:systems management|systems management]]]] service offered by Google. It provides performance and diagnostics data (in the form of monitoring, logging, tracing, error reporting, and alerting) to [[w:public cloud|public cloud]] users. Stackdriver is a hybrid cloud solution, providing support for both [[w:Google Cloud Platform|Google Cloud]] and [[w:Amazon Web Services|AWS]] cloud environments. (Wikipedia)

'''[[w:Google App Engine|Google App Engine]]''' (often referred to as '''GAE''' or simply '''App Engine''') is a [[w:web framework|web framework]] and [[w:cloud computing|cloud computing]] platform for developing and hosting [[w:web application|web application]]s in Google-managed [[w:data center|data center]]s. Applications are [[w:Sandbox (computer security)|sandbox]]ed and run across multiple servers. App Engine offers automatic scaling for web applications—as the number of requests increases for an application, App Engine automatically allocates more resources for the web application to handle the additional demand.
