Learning Path: Modern DevOps

Mastering DevOps 38 lectures 05:47:41 Mastering DevOps - The Course Overview This video gives an overview of the entire course. Is DevOps for Me? There is a lot of press about DevOps, but really what's in it for you? In this video, we show the results of the science behind the approach and start looking at software development in a whole new way.

• Look at DevOps, the buzzword
• Why should I care?
• Look at the software development "factory"

The First Way – Systems Thinking In Gene Kim's DevOps model of the three ways, the first way is about optimizing delivery of our software. In this video, we are exposed to systems thinking and ways we can improve our speed of delivery.

• Review the first way
• Take a look at examples of things that improve flow
• Check out the barriers that impede flow

The Second Way – Feedback Loops Getting feedback on our improvement is the only way to know if the changes we make are having an effect. In this video, we examine the ways to get feedback and the benefits of collecting feedback.

• Review the second way
• Take a look at examples of the ways to get feedback
• Check out the barriers to collecting feedback

The Third Way – Culture of Experimentation The fastest and best way to move quickly is to continually experiment with new ideas, concepts and techniques. This video discusses how continually testing, probing, and analyzing lead to the highest performing teams.

• Review the third way
• Take a look at the examples of a culture of experimentation
• Understand the barriers to a culture of experimentation

The Principle of Kaizen The components of the three ways, used together, enable us to move faster, learn quicker, and improve more than ever in the past. The principle of Kaizen is the rationale for these improvements.

• Make our first Salt state
• Build on the knowledge to create your first Salt state
• Where to go from here?

Configuration Management for Distributed Systems Being able to configure a single virtual machine—being able to control thousands of machines from a single location—is how we leverage automation to do things we could only dream of in the past. In this video, we learn how to do just that.

• We review our Salt State
• Install a Saltmaster and Minion
• Verify connectivity
• Improve our Salt State
• Serve our state from a Saltmaster

What about Containers? Containers are one of the hottest topics in DevOps at the moment. Why? We will look at what came before, what's great about containers now, and how to choose between containers and configuration management.

• What are containers?
• Advantages of containers
• When do I use which?

Building and Running a Docker Container We've built and run a virtual machine using configuration management. In this video, we do the same for containers as we learn about Docker and build and run our first container.

• Install Docker
• Build a Docker image
• Run a Docker container
• Connect to a Docker container

What is Continuous Delivery? We know that automation is important for DevOps, and Continuous Delivery is critical to being able to deploy quickly and satisfy the 1st way of DevOps. We look at how a proper continuous delivery pipeline is formed.

• What is Continuous Delivery?
• What does a CD system look like?
