Docker is an open-source project that automates the deployment of applications inside software containers.

Quote of features from Docker web pages:

Computer access control Confidence: 75% Arrow up

In computer security, general access control includes identification, authorization, authentication, access approval, and audit.

A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.

Authentication and access control are often combined into a single operation, so that access is approved based on successful authentication, or based on an anonymous access token.

Authentication methods and tokens include passwords, biometric scans, physical keys, electronic keys and devices, hidden paths, social barriers, and monitoring by humans and automated systems.

Google Cloud Platform Confidence: 70% Arrow up

Google Cloud Platform is a cloud computing service by Google that offers hosting on the same supporting infrastructure that Google uses internally for end-user products like Google Search and YouTube.

Cloud Platform provides developer products to build a range of programs from simple websites to complex applications.

Operating-system-level virtualization Confidence: 64% Arrow
Non-breaking space Confidence: 63% Arrow
