Study Tips

  • Always look for information in the official documentation of the tool. Practically everything we'll work with is open source. The main tools are very well documented, especially those from HashiCorp. Learn to use the documentation to your advantage and how to quickly find what you need.

  • It's not necessary to be an expert in any tool, but it's necessary to know how to use it, at least the basics, and know its limits. The documentation is always available to help when we need it.

  • Take online courses on Alura or Udemy and even on YouTube following tutorials to get direction, but don't think they're sufficient to understand the tool's limits. Continue studying along with the documentation.

  • Follow study communities, YouTube channels, Twitch. Also follow the main companies on LinkedIn and Twitter.

  • Documenting your studies helps to solidify knowledge.

  • If you can, have a server to be your playground at home, but only if you can.

If you notice carefully, many content creators talk about the same topic several times. If you already know about the tool, stay updated on new releases and not on videos. Always focus on new knowledge.

Life tip​

Practicing is the best learning method, but don't forget that making it work doesn't mean you have mastery of the tool. Making it work in a controlled environment is not real life.

Understand the theory of things, do several installations with different scenarios, not only to learn, but to know how to fix it when it breaks. Don't skip theory.

Understanding why things work helps you absorb information better, because everything will make sense. At the same time, understanding the theory makes you more creative and lets you use solutions in different ways adapted to different scenarios.

But there's also no point in understanding everything to the point of seeming to reinvent the wheel. Use good judgment in the time spent between learning theory and practicing.

If I had six hours to cut down a tree, I'd spend the first four hours sharpening the axe.

The Pareto principle tells us that 20% of knowledge in any content can achieve 80% of results. In that 20%, study a lot, and in the other 80%, study less, but still study.

Tip for entering the market​

  • Create public repositories of your studies. Anyone can say they know something, but a study repository, in addition to spreading knowledge, proves that you know and will give you an initial portfolio.

  • If necessary, create a blog to create your study roadmaps, your story.

  • Out of sight, out of mind. Look to go to DevOps conferences and make friendships.

  • Always look for information in the official documentation of the tool. Practically everything we'll work with is open source. The main tools are very well documented, especially those from HashiCorp. Learn to use these documentations to your advantage and how to quickly find what you need.

  • It's not necessary to be an expert in any tool, but it's necessary to know how to use it, at least the basics, and know its limits. The documentation is always available to help on our side of the internet.

  • Follow study communities, YouTube channels, Twitch. Also follow the main companies on LinkedIn and Twitter.

  • If you've already managed to enter the job market, prioritize learning the tools the company needs, but set aside time to learn new ones.
