"DevOps Fundamentals: A Beginner's Guide" Free Training Voucher

Introduction to DevOps: DevOps, a portmanteau of "Development" and "Operations," is a cultural and technical movement that emphasizes collaboration, communication, and integration between software development and IT operations teams. It aims to automate the process of software delivery and infrastructure changes, leading to faster and more reliable releases.

Key Principles: DevOps is guided by several key principles:

• Collaboration: Encouraging close collaboration between development, operations, and other stakeholders.
• Automation: Automating repetitive tasks to streamline processes and reduce manual errors.
• Continuous Integration (CI): Integrating code changes frequently to detect and fix issues early.
• Continuous Delivery (CD): Ensuring that code changes can be reliably and rapidly deployed to production.
• Monitoring and Feedback: Implementing monitoring tools to provide feedback on system performance and user experience.

Cultural Aspects: DevOps is as much about culture as it is about tools and practices. It promotes a culture of shared responsibility, transparency, and continuous improvement. Teams work together towards common goals, breaking down silos and fostering a blame-free environment where failures are seen as opportunities for learning.

Core Practices: Several practices are fundamental to DevOps success:

• Infrastructure as Code (IaC): Treating infrastructure configurations as code, allowing for automated provisioning and management.
• Configuration Management: Managing and maintaining system configurations consistently across environments.
• Version Control: Using version control systems like Git to track changes to code and infrastructure configurations.
• Continuous Integration and Continuous Delivery (CI/CD): Automating the process of building, testing, and deploying applications.
• Microservices: Architecting applications as a collection of loosely coupled, independently deployable services.
• Containerization: Using containers to package and deploy applications along with their dependencies in a consistent and portable manner.
