What happens once your software is actually running in production? Ensuring that it stays up-and-running is important. And depending on what the system does, and how much traffic it needs to handle, that may not be particularly easy.

There are systems that will allow developers to run their code and not need to think about it. Platforms as a service option like Google’s App Engine go a long way to reducing and, in some companies, removing operations. However, not every system can or will run on such platforms. Which means that having qualified operations engineers is an important thing.

The role of an operations engineer is continually evolving; which isn’t a surprise since changes in technology never slows down.

So, if the job falls on you to keep a system up-and-running, where do you start? What needs to happen? These are the questions this Course aims to answer.

In this Course, we take a look at some of tasks that operations engineers need to address. I use the term operations engineer as an umbrella, to cover a wide variety of job titles. Titles such as ops engineer, operations engineer, site reliability engineer, devops engineer, among others, all fall under this umbrella.

Regardless of the name of the title, the responsibilities involve keeping a system up-and-running, with little or no downtime. And that’s a tough thing to do because there are a lot of moving parts.

If you’re just starting out, and are interested in one of those roles, then the fundamentals in this Course may be just what you need. These fundamentals will prepare you for more advanced Courses on specific cloud providers and their certifications.

Topics such as high availability are often covered in advanced Courses, however they tend to be specific to a cloud provider. So this Course will help you to learn the basics without needing to know a specific cloud provider.
