First, let’s start with what is DevOps and the problem it solves.

The word DevOps is a combination of development (Dev) and Operations (Ops). DevOps aims to improve the efficiency and reliability of software development and deployment and to make it easier for organizations to deliver high-quality software faster. It is a principle that emphasizes collaboration, communication, and integration between software developers and IT operations professionals. The goal of DevOps is to enable organizations to quickly and reliably deliver high-quality software by automating processes, increasing efficiency, and reducing the risk of errors.

Some of the key principles of DevOps include:

  • Continuous integration and delivery: Developers regularly merge their code changes into a central repository, and automated processes build, test, and deploy the software to various environments.
  • Automation: Automation is used to manage and deploy infrastructure, as well as to build, test, and deploy software.
  • Monitoring and feedback: DevOps practices include monitoring the performance and availability of software in production, and using that feedback to improve the development and deployment process.
  • Collaboration and communication: DevOps promotes collaboration and communication between developers and IT operations professionals, and encourages cross-functional teams that are responsible for the entire software development life cycle.

Tools you need to learn for DevOps

DevOps uses lots of tools in its operation. Here are some of the ones you need to know as a DevOps engineer.

  1. Knowledge of cloud platforms. The popular ones are AWS, Azure or Google cloud platform (GCP). AWS is the most popular among them and it has lots of services that are not available on other platforms.
  2. Understanding of Linux commands and administration. Most servers use Linux as such, knowing how to navigate your way is very essential. Especially how to set up a server, navigate the directories, install packages, manage users and more
  3. Knowledge of programming language. New entrants to DevOps shy away from programming. While the software is built by other developers, understanding the codes and how they work can make a lot of difference. Python, Java or javascript are good options. With Python being easier to learn.
  4. Source code management platforms like Github, GitLab or bitbucket are popular platforms where developers collaborate and manage their source code.
  5. Continuous integration and continuous delivery (CI/CD) are essential to integrate, test and build the source code. Jenkins is one of the open sources tools used to handle CI/CD. It also has plugins that make it compatible with other tools.
  6. Infrastructure as code (IaC) helps to automate the provisioning of infrastructure on your preferred cloud platform. Terraform is a good choice as it has lots of modules and can work with several providers.
  7. One way to mitigate the headache developers have when deploying their apps is by using containers. Docker handles this well with Kubernetes which is used for container orchestration.
  8. Knowledge of code analysis tools like sonar cloud will also be a plus
  9. Being able to configure your servers at once with ease is essential. Ansible, chef or puppet are essential to achieve this. With ansible being easier and gaining more popularity.
  10. Lastly, being able to monitor your infrastructure is important. Prometheus and Grafana are good choices for monitoring.
