Top 10 things to learn to become a DevOps Engineer

DevOps engineers are the rock stars of IT. They are the people who keep your infrastructure running smoothly and help you scale up as fast as possible to meet demand. You can become a DevOps engineer by learning these 10 things:

Terraform

Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. It’s used by companies like Airbnb, Box, and Netflix to automate the creation of infrastructure on any cloud provider including AWS, Google Cloud, Microsoft Azure, and many more.

Terraform works with your existing systems, so you don't have to build everything from scratch again or spend time figuring out how things work. You can also use it as a central repository for your data center configuration files, so they're always available when needed: no more copying and pasting between dozens of different environments!

Ansible

Ansible is a simple and powerful tool to automate IT operations. It can be used to provision, configure, manage and deploy applications on any modern Linux distribution.

Ansible has a low learning curve, can be easily installed on all major distributions including RHEL/CentOS/Oracle Linux/Ubuntu 18.04, etc., supports Python 3 or 2 (Python 2 will not work in this tutorial), has no dependencies, so it should run everywhere without any issues, but you may need some additional libraries if you want certain features like ssh access from remote machines or virtual machine configuration management using VCSes like Gitlab CI/CD does require them though both are optional depending on your needs

Golang

Golang is a programming language that is used for creating applications. It's simple and easy to learn, which makes it an attractive choice for new programmers. The Go runtime (which the compiler runs on) provides concurrency features, garbage collection, and support for interfaces and type safety.

To get started with Golang:

• Download the Go SDK or the installer from Microsoft's website; they are free! You'll need an internet connection to download them both, though, so make sure you've got some time before starting this process if you're in a rush. If not, then use any other method available here or elsewhere online, such as downloading directly through our site using your browser instead (see below).

CD/CI

The DevOps Engineer is responsible for developing, implementing, and maintaining a continuous delivery process. This process encompasses the entire lifecycle of an application, from the moment it is conceived to its eventual retirement. The DevOps Engineer is also responsible for automating all aspects of this lifecycle, including deployment, testing, and monitoring.

The DevOps Engineer also has a deep understanding of the codebase they are working with. This means they can make well-informed decisions about how to improve the software's performance in terms of speed, scalability, or security. They also have a strong knowledge of how to use application development tools like Jenkins or Gitlab CI/CD to automate processes such as continuous integration (CI) and continuous delivery (CD).

Bash scripting

Bash is a shell scripting language, which means it’s used to automate tasks. It’s also the default command line interface (CLI) in Linux and Mac OS X systems. Bash can be used to create scripts and software, as well as DevOps!

Bash is very popular because it has a simple syntax that makes it easy to learn, but powerful enough for complex tasks. This makes Bash an excellent tool for automating processes like building software or configuring servers.

Python

Python is a high-level, general-purpose programming language. It's often used in web development, data science, and machine learning. It's also a popular choice for building DevOps tools. Python is easy to learn but has a large ecosystem of libraries that make it incredibly powerful. You can use Python to create standalone programs or scripts, as well as web applications and websites.

As you can see from the above description of Python's purpose, it's not just for web applications anymore! 

Git and GitHub

• Git is a version control system that allows you to store and manage your code, projects, and files. It's a distributed revision control system (DRCS) that allows multiple people to work on the same project at the same time.
• GitHub is a web-based hosting service for version control using Git. It’s the largest code host in the world, with over 2 million code repositories hosted on it!

Cloud Architecture on AWS, GCP, Azure (at least one)

AWS, GCP, and Azure are the most popular public cloud providers. AWS has the most mature offering, but can be expensive for large organizations. GCP is a close second, with its own unique problems that may not be worth dealing with if you’re just starting out. Azure is a distant third in terms of maturity and usability compared to AWS or GCP; however, if you don't need full control over your infrastructure then this may be an excellent choice for startups looking to get up and running quickly on an affordable footing while they learn what they need to know about DevOps practices like automation tests before branching out into production environments later down the line once they've got their ducks in order (and maybe even start building some cool stuff).

Kubernetes/Docker

Kubernetes is a container orchestration tool that allows you to create and manage Docker containers. The primary benefit of using Kubernetes is its ability to deploy your application on clusters of hosts, which gives you scalability and reliability.

Docker has become popular due to its ease of use and portability. It's one of the top tools for developing software in a distributed environment because it allows developers to focus on their code without worrying about infrastructure details or configuration management tasks. Docker also allows users to easily run multiple applications side by side without having any conflict between them—which makes it easier than ever before!

Linux/Unix system fundamentals and best practices.

• Linux/Unix system fundamentals and best practices.
• Linux shell scripting.
• Linux file permissions, ownership, and permissions.
• File system hierarchy in a Unix-like environment (i.e., /etc directory).
• How to create files on the /etc directory, who can access them, and what they are allowed to do with them (i.e., read, write).
• What is a “directory” under Unix systems? A directory is just another name for a folder containing other folders or files within it that you can view using your operating system's file manager application or command line tool called 'ls'. You may also see this term used when discussing virtual machines in cloud computing environments such as Amazon Web Services or Microsoft Azure; however, there are differences between these terms which we'll cover later on in this article when discussing containers
