The goal of this course is to take existing IT professionals, whether they come from software development or operations, and help them appreciate the challenges facing companies who are looking to embrace scalable software deployment as well as the architectures and thought processes they can use to address these challenges.
Students will start with a presentation of the problem as it stands today, then dive into the DevOps workflow and a survey of the system architectures currently being used to address this problem.
Why Take This Course? Based on Puppetlab's "State of DevOps" report for 2013 and 2014,
high-performing organizations are deploying code 30 times more frequently, with
50 percent fewer failures than their lower-performing counterparts.
The report states:
>We can now assert with confidence that high IT performance correlates with strong business performance, helping to boost productivity, profitability and market.
Adopting DevOps is the way most companies improve the performance of their IT organisations, and this course will help you take the first steps towards that goal.

How do these MOOCs or free online courses work?
MOOCs are designed for an online audience, teaching primarily through short (5-20 min.) pre recorded video lectures, that you watch on weekly schedule when convenient for you. They also have student discussion forums, homework/assignments, and online quizzes or exams.
Hchancompleted this course, spending 1 hours a week on it and found the course difficulty to be easy.
A very quick 3-lesson intro to the basic concept of devops. Honestly I found the practice exercises to be more trouble than they were worth - they're basically just uninteresting exercises in setting up various environments, rather than actual "how to use it" tutorials. This is understandable for the extremely short length of the course, because a module on each individual tool alone (e.g., Chef/Puppet/Vagrant) would probably cover many weeks per tool. My recommendation is to zoom through the lectures, paying special attention to the overall concepts of the devops movement, and skip the programming assignments. Based on what you need to use at work, you can search around for more comprehensive tutorials on each individual tool - you won't be able to learn them in this course whether or not you spend time setting up the environments provided.
Course is extremely low quality, typical of most udacity courses. Instructor talks way too fast (yes, I know I can slow it down, but 50% slow down is TOO SLOW). I followed the first hands-on lab instructions to the letter and it did not work. No help on the forums. I guess that's what you get for free...
