Description

DC/OS Fundamentals

Do you remember the days of deploying a N tier application to on-premises servers? The planning that went into determining the right amount of hardware to use so that you weren’t under or significantly over-provisioned. Deployments were often problematic, because what ran well on the developer’s computer, didn’t always work outside of their environment. Deployments also were assumed to cause downtime, and scheduled during non-peak hours.

In the event of a hardware failure, your app might have been unavailable depending on how much hardware you had access to, and how the application was designed. Failovers may or may not have been automatic, and frankly it was all a lot of work.

Well, if you thought that was difficult, imagine trying to do all of this at the scale of Google, Facebook, Twitter, Netflix, or similar companies.

All of the companies I just mentioned found that hyperscale computing required a new way to look at things. And regardless of the actual tools that they used, they all had the same solution, which was to treat their entire data center as a single entity.

And that’s what DC/OS does: it’s a central OS for your data center, and it’s the topic of this course.
