Docker is the worldwide choice for containers. You can run a CentOS container on Ubuntu, or a Debian container on Alpine Linux. These containers are fast to build and easy to deploy. Docker has two core components, the Docker Engine and the Docker containers communicating with each other for smooth app deployments. Today it is used by top companies like JP Morgan Chase, PayPal, New York Times, AWS, and Google.
Other major companies that deploy their applications on Docker include Business Insider, Spotify, Yelp, ADP, eBay, Expedia, Groupon, ING, New Relic, Oxford University Press, Sage, Shopify, The Washington Post, and Uber.
