I often get asked what is it that I actually do, from both people within the Tech industry as well as outside and I dont always have a simple explanation for that, so I thought I should try and write this down. What is it that I do and what is this DevOps thing really?
A Wikipedia article about the subject (https://en.wikipedia.org/wiki/DevOps) starts out by defining it as:
DevOps is a set of software development practices that combine software development (Dev) and information-technology operations (Ops) to shorten the systems-development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives.
And that pretty much describes it pretty well, but lets try and boil it down and talk about what kind of tasks you would be doing and what kind of technologies and software you would use. Now this is going to be from my personal experience, yours might differ but the basic principles should be there.
One of the things you defninitly need as a DevOps enginner is communication skills, you are going to have to talk to a lot of people in your daily job with everyone from Developers to Customers, your IT partners, your customers IT partners, Project leaders and Managers. Since what you do is touching everything from local development up to the production infrastructure you affect them all and you need to work together and be open and transparent about all this.
Is this a complete list of what you do as a DevOps engineer? No, but its a start and its very much colored from my personal experience and I would go back to the Wikipedia quote, it’s all about making delievery of your applications from 0 to 100 as automatic and easy as possible.
And trying and have that mindset throughout all the software and infrastructure you use, always think “can we automate this process?” and “can we make this part of the repository and make it more transparent?” so whenever you quit your job for new adventures our you get hit by a bus your company is Not screwed because you where the only one who knew how “..that odd server was setup”.
So I hope that was helpful in understanding what a DevOps engineer does, do you agree or have anything to add, please be vocal and make your voice heard in the comments below.
