Let's get started!

What is DevOps?

DevOps is short for Development (Dev) and Operations (Ops). It is a cultural and professional movement that seeks to bridge the gap between software development and software operations.

In the past, developers would code and then "hand it over" to the operations folks for deployment and upkeep. This resulted in bottlenecks, miscommunication, and slowdowns.

DevOps addresses this issue by putting developers and operations people together during the software's lifetime.

Most important features of DevOps:

Collaborative culture among teams.
Automating manual tasks such as testing and deployment
Continuous Integration (CI) and Continuous Delivery (CD) pipelines.
Real-time monitoring of apps.
Scalable infrastructure via cloud and containerization.

In a nutshell, DevOps = People + Processes + Tools working together for quicker software release.

Why is DevOps Important?

DevOps matters because it enables organizations to deliver high-quality software quickly and more effectively. Speed and quality are more crucial than ever in today's competitive IT market.

Below are some of the most important reasons why DevOps is crucial:

Faster Time-to-Market – DevOps facilitates faster releases via automation.
Better Collaboration – Developers and operations collaborate in harmony.
Fewer Errors – Automated testing eliminates bugs and human errors.
Improved Customer Satisfaction – Smoother updates and bug fixes enhance user experience.
Scalability and Flexibility – Applications are made scalable through cloud integration.
Cost Efficiency – Time and resource wastage is minimized through automation.

DevOps Principles

In order to fully grasp what is DevOps, we need to consider its fundamental principles:

Collaboration & Communication – Smooth teamwork among teams.
Automation – Repetitive tasks such as deployment, testing, and monitoring are automated.
Continuous Integration (CI) – Coders often integrate their code into a central codebase.
Continuous Delivery (CD) – Making sure that software is deployable at all times.
Monitoring & Feedback – Constant monitoring of system performance to get better.
Infrastructure as Code (IaC) – Infrastructure is controlled using code for scalability and consistency.

These form a continuous cycle of improvement.

The DevOps Lifecycle

The DevOps lifecycle is a sequence of phases that provide continuous software delivery. It is typically illustrated as an infinity loop, which signifies ongoing processes.

The key phases are:

Plan – Specify project requirements and plans
Code – Developers author and maintain code through version control systems.
Build – Code is built and made ready for deployment.
Test – Automated testing validates software quality.
Release – Application is packaged and ready for deployment.
Deploy – Software is rolled out to production environments.
Operate – Applications are observed in real-world usage.
Monitor – Ongoing feedback enhances performance and user satisfaction.

This process ensures feedback is constantly folded into the next iteration.

Popular DevOps Tools

DevOps depends on robust tools to automate. Some of the most popular DevOps tools are:

Version Control – Git
CI/CD – Jenkins, GitLab CI/CD, Azure DevOps
Configuration Management – Ansible, Puppet, Chef
Containerization & Orchestration – Docker, Kubernetes
Monitoring – Nagios, Prometheus, Grafana
Cloud Platforms – AWS, Azure, Google Cloud

It is mandatory to learn these tools for any potential DevOps engineer.
