Learn Version Control: Familiarize yourself with Git, as version control is a crucial skill in DevOps. You can start with online tutorials and documentation like the "Pro Git" book by Scott Chacon and Ben Straub.
Master the Command Line: DevOps heavily relies on command-line tools for automation and management. Practice using the terminal extensively and learn essential commands and scripting (e.g., Bash, PowerShell).
Infrastructure as Code (IaC): Get familiar with IaC tools like Terraform or Ansible, which allow you to manage and provision infrastructure programmatically. Online courses like those on Udemy or Pluralsight can be helpful.
Continuous Integration and Deployment (CI/CD): Understanding CI/CD pipelines is crucial in DevOps. Consider learning tools like Jenkins, GitLab CI/CD, or CircleCI. "Continuous Delivery" by Jez Humble and David Farley is an excellent book on this topic.
Cloud Platforms: Familiarize yourself with cloud providers like AWS, Azure, or Google Cloud Platform. You can take vendor-specific certifications or explore resources like the AWS Well-Architected Framework.
