Proficiency in Linux and Scripting Linux is a foundational operating system in DevOps. Engineers must understand Linux commands, system administration, and scripting languages like Bash, Python, or Ruby to automate tasks and manage infrastructure efficiently.
2. Continuous Integration and Continuous Deployment (CI/CD) CI/CD pipelines are the backbone of DevOps. Engineers should be skilled in tools like Jenkins, GitLab CI, and GitHub Actions to automate code integration, testing, and deployment.
3. Containerization and Orchestration Technologies like Docker and Kubernetes are essential for packaging applications and managing them at scale. These tools enable portability, scalability, and efficient resource utilization.
4. Infrastructure as Code (IaC) IaC tools like Terraform, Ansible, and CloudFormation allow engineers to define and manage infrastructure programmatically. This ensures consistency, scalability, and automation.
