The three ways can guide your strategic approach to DevOps.
(epic music)…- Welcome back.…Let's talk about principles you can use to guide you…in taking the core DevOps values and bringing them to life.…The most respected set of principles is called…The Three Ways.…This model was developed by Gene Kim,…author of "Visible Ops" and "The Phoenix Project,"…and Mike Orzen, author of "Lean IT."…The three ways they propose…are systems thinking, amplifying feedback loops,…and a culture of continuous experimentation and learning.…
The first way, systems thinking, tells us that we should…make sure to focus on the overall outcome of the entire…pipeline in our value chain.…It's easy to make the mistake of optimizing one part…of that chain at the expense of overall results.…When you're trying to optimize performance…in an application, for example, increasing performance…or system resources in one area causes the bottleneck…to move sometimes to an unexpected place.…Adding more applications servers, for example, can overwhelm…a database server with connections and bring it down.…
You have to understand the whole system to optimize it well.…
In this course, well-known DevOps practitioners Ernest Mueller and James Wickett provide an overview of the DevOps movement, focusing on the core value of CAMS (culture, automation, measurement, and sharing). They cover the various methodologies and tools an organization can adopt to transition into DevOps, looking at both agile and lean project management principles and how old-school principles like ITIL, ITSM, and SDLC fit within DevOps.
The course concludes with a discussion of the three main tenants of DevOps—infrastructure automation, continuous delivery, and reliability engineering—as well as some additional resources and a brief look into what the future holds as organizations transition from the cloud to serverless architectures.
