Introduction to DevOps: Bridging Development and Operations

DevOps is a culture and set of practices that bring software developers and IT operations teams together. The goal is to improve collaboration, speed up delivery, and ensure reliable software.

Why DevOps?

Traditionally, developers build software and operations teams deploy and maintain it. This can cause delays and misunderstandings. DevOps breaks down these silos to create faster, more efficient workflows.

Key Practices

• Continuous Integration (CI): Developers frequently merge code changes into a shared repository, automatically tested.

• Continuous Delivery (CD): Automating the release of software to production.

• Infrastructure as Code: Managing infrastructure through code to enable automation.

Benefits

• Faster releases and updates.

• Improved quality through automated testing.

• Better collaboration and communication.

• Increased stability and fewer outages.

Tools to Know

• Jenkins for automation.

• Docker for containerization.

• Kubernetes for orchestration.

• Git for version control.

Getting Started

Learn basic Linux commands, get familiar with Git, and explore simple CI/CD pipelines.

Summary

DevOps helps teams build, test, and release software faster and with higher quality through collaboration and automation.
