In this guide, we’ll explore the best free courses available, key topics to focus on, and actionable steps to kickstart your learning journey in DevOps and automation.
What is DevOps?
DevOps is a combination of practices, tools, and a cultural philosophy designed to improve collaboration between development and IT operations teams.
The primary goal of DevOps is to shorten the software development lifecycle, ensuring faster delivery of high-quality software.
Key principles of DevOps include:
- Continuous Integration (CI): Frequent merging of code changes to a central repository.
- Continuous Delivery (CD): Automated deployment of code to production.
- Automation: Use of tools and scripts to reduce manual work and eliminate errors.
- Collaboration: Breaking silos between development, operations, and quality assurance teams.
What is Automation in DevOps?
Automation in DevOps involves using tools and scripts to automate repetitive tasks such as:
- Infrastructure provisioning.
- Configuration management.
- Code deployment.
- Monitoring and logging.
Automation ensures consistency, reduces errors, and improves the efficiency of DevOps pipelines.
