DevOps requires you to know many facets of people and technology. If you're interested in starting your journey into the world of DevOps, then take the time to know what you are getting yourself into, be ready to put in some work, and be ready to push out of your comfort zone.

Know What You're Getting Yourself Into

Working in a DevOps job where you're responsible for both coding and operational tasks means that you need to be able to shift mental gears. Mental context switching comes at a cost. You need to be able to pull yourself out of one mindset and switch to another, and you need to be able to prioritize. Accept your limitations and know when it's prudent to request more resources to handle the load.

The amount of context switching will vary depending on the business. Let's say that you join a startup, and you're the only DevOps person on the team. In this scenario, you're most likely the operations team and still responsible for some coding tasks as well.

This means that you need to tackle operations tasks as they come in. In this instance, Scrum and Agile will only carry you so far, you'll have to take more of a GTD approach. If you come from a development background, you will be tempted to put coding first as you have deadlines. However, if you are the operations team, then operations must come first.

When you become a part of the operations team, employees at your business are now your customers too. Some days you can churn out code, other days are going to be an onslaught of important, time-sensitive requests.

At the business that I currently work for, I took on the DevOps role so that other developers could focus on coding. One of the developers that I work with has exceptional code output. However, operational tasks were impeding their productivity.

It was an obvious choice for me to jump in and take over the operational tasks so that the other developer could focus his efforts on bringing new features to customers. It's simply good business. Ego can get in the way of good business and DevOps. Leave your ego at home.

In a bigger business, you may have a DevOps team where there is more breathing room to focus on things that you're more interested in, whether it's more coding or working with systems.

Emergencies happen. When an emergency arises, you need to be able to calmly assess the situation, avoid the blame game, and provide solutions. Don't react. Respond.

If you're too excitable or easily get caught up in the emotions of a given situation, DevOps may be your trial of fire. Work on pulling yourself outside of a situation so that you can see the whole picture and work towards solving the problem.

Never play the blame game. Be the person who gets things done.

Dive Into DevOps

Start small.

Taking on too much will overwhelm you and stifle progress. After you’ve done a few iterations of taking small steps, you'll be further along the journey than you realize.

"It's a dangerous business, Frodo, going out your door. You step onto the road, and if you don't keep your feet, there's no knowing where you might be swept off to.” - Bilbo Baggins.

If you're a developer, take one of your side projects and set up continuous delivery for the project. I would keep it simple and use something like Travis CI or AppVeyor and have your final output published somewhere. If you're using something like node, you could set up nightly builds for NPM. If its .NET you could use a service like MyGet.

The second thing I would do as a developer is to focus on learning SSH, security access, and scheduled tasks. One of the things I've seen developers struggle with is locking down systems, so it's worth taking the time to dive into user access permissions. If you're on Windows, learn the windows task scheduler. If you're on Linux, learn to setup cron jobs.

If you're from the operations and systems side of things, pick a scripting language that suits your needs. If you're working for a company that uses Microsoft technology, I'd suggest that you learn the Powershell scripting language and a language that compiles to .NET like C# or F#. If you're using open source technologies, I'd suggest learning bash and a language like Ruby or Python. Puppet and Chef use Ruby. Salt Stack uses Python.

Build a simple web application with the language of your choice. That should give you enough familiarity with a language for you to start creating scripts that automate tasks.

Read into DevOps books like Continuous Delivery or Continuous Delivery and DevOps Quickstart Guid.

Expand your knowledge. Explore tools. Work on your intercommunication skills.

Create a list of tasks that you wish to automate. Then create a habit out of reducing that list.

Build A Habit Out Of Automating Infrastructure.

Make it a habit to find time to automate your infrastructure while continuing to support your business. It's rare to get into a position that only focuses on automating infrastructure constantly as one's sole job, so it's important to be able to carve out time to remove mundane work so that you can focus your time and value on tasks that can't be automated.

A habit loop is made up of three things. A cue, a routine, and a reward. For example, at 2pm your alarm goes off (cue). You go for a short run (routine). You feel awake and refreshed (reward).

Design a cue that works for you. For example, every Friday at 2pm you could switch gears to work on automation. Spend some time on automating a task or infrastructure need (Routine), then find a reward that suits your lifestyle. A reward could be having a treat on Friday to celebrate all the hard work for the week or going home early (if your business permits this). Maybe learning something new is the reward and in that case, you spend a little time each week with a new DevOps related technology.

Once you've removed some of the repetitive tasks that waste time, then you'll find yourself with enough time to take on bigger automation projects that seemed impossible to get to before.

Repeat this process ad infinitum (To infinity and beyond).

Lastly, Always Write and Communicate

Whether you plan on going into DevOps or not, the ability to communicate will set you apart from others in your field.

In DevOps, communication becomes a necessity because the value you provide may not always be apparent to everyone around you. Furthermore, you need to be able to resolve group conflicts, persuasively elicit buy-in, and provide a vision that people can follow.

Always strive to improve your communication skills. Read books. Write. Work on your non-verbal communication skills. Non-verbal communication accounts for 93% of communication. It's worth knowing that messages that your body language sends could be preventing you from getting your ideas across.

Communicating in a plain language to the lowest common denominator of your intended audience is your goal. People that are technical and nontechnical need to understand problems, solutions, and the value that you are giving them.

Learn to use the right adjectives to paint bright illustrations in the minds of your readers to help them conceptualize hard-to-understand topics.

The ability to persuade with writing is almost a lost art. It is a skill that transcends careers, disciplines, and fields of study. Used correctly, you can provide vision to guide your business into becoming a lean competitor that provides exceptional value to customers. At the end of the day, DevOps exists so that you can provide exceptional value to customers.

Let your words guide and inspire the people around you.

Off You Go

All this is easier said than done. It takes time, practice, and years of experience. Don't be discouraged and don't give up. Instead, find things that light up your passion and focus on taking small incremental steps that allow you to win.

You'll be there before you know it.
