This course consists of 3 lessons which will take you from absolutely zero knowledge about the Linux operating system all the way to hosting your very own data-driven application that is publically accessible to everyone in the world!
## Lesson 1 - Intro to Linux
In this lesson you will be introduced to the Linux operating system and the various available distributions. You will then setup your very own Linux virtual machine on your own computer and explore that system, learning how the filesystem is organized and identifying key files.
## Lesson 2- Linux Security
As you unleash your new server onto the Internet you'll need to be a good citizen - and this means, **security**! In this lesson, you'll learn how to execute administrative tasks, update the software on your system, install new software, and manage users. You'll then learn how to implement even stronger authentication mechanisms, how to interpret Linux file permission and, finally, how to configure a firewall to keep your system secure.
## Lesson 3 - Web Application Servers
In this lesson you'll transform your secure and safe barebones server into a fully functional web application server by installing and configuring the Apache HTTP Server and PostgreSQL database server. You'll then write a very basic Python WSGI application that can query a database and present that data upon a web request.

Udacity est une entreprise fondé par Sebastian Thrun, David Stavens, et Mike Sokolsky offrant massives des cours en ligne ouverts (MOOCs).
Selon Thrun, l'origine du nom Udacity vient de la volonté de l'entreprise d'être "audacieux pour vous, l'étudiant ". Bien que Udacity se concentrait à l'origine sur une offre de cours universitaires, la plateforme se concentre désormais plus sur de formations destinés aux professionnels.
