What is DevOps


4 min read

Welcome to the world of DevOps

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops), aiming to shorten the system development life cycle and deliver high-quality software continuously.


DevOps is a combination of two words: "Development" and "Operations." It's not just a set of tools but a philosophy that aims to fill the gap between developers and operations teams.

The goal? To deliver high-quality software faster, more reliably, and with fewer interceptions.


DevOps is a methodology that allows a single team to manage the entire SDLC (software development life cycle), that is developing, testing, deployment, and operation.

Why DevOps

  • Faster Delivery

  • Improved Collaboration

  • Reduced Errors

  • Enhanced Feedback Loops

Key DevOps Principles:

  • Collaboration: Working like a team of friends, sharing ideas and tasks, so everyone knows what's happening, like playing together instead of alone.

  • Automation: Having a computer robot do the boring tasks for you, like a helpful friend, so you can focus on more interesting things.

  • Continuous Integration (CI): Like building a puzzle together, adding your pieces as soon as they're ready, so you can see the complete picture bit by bit.

  • Continuous Delivery (CD): Similar to magic pizza delivery, as soon as the code is ready, it automatically goes to where it needs to be without someone carrying it there.

  • Infrastructure as Code (IaC): Infrastructure as Code involves managing and provisioning infrastructure through code rather than manual processes. In AWS, tools like AWS CloudFormation allow users to define and provision AWS infrastructure in a declarative manner.


    It's like having a recipe for your computer setup, so you can easily recreate it or share it like using a cooking book for computers.

Road Map to start the DevOps journey

  1. Learn Linux Basics:

    • Familiarize yourself with basic Linux commands, file systems, permissions, and shell scripting.

    • Learn about package management systems (e.g., apt, yum) and basic system administration tasks.

  2. Version Control:

    • Learn a version control system, such as Git. Understand branching, merging, and basic workflows.

    • Set up a Git repository and practice collaborating with others using Git.

  3. Scripting and Automation:

    • Improve your scripting skills with languages like Bash or Python. Automation is a core aspect of DevOps.

    • Automate routine tasks using tools like Ansible, Puppet, or Chef.

  4. Infrastructure as Code (IaC):

    • Understand the concept of Infrastructure as Code.

    • Learn tools like Terraform or Ansible for provisioning and managing infrastructure.

  5. Containerization:

    • Learn about containerization with Docker. Understand container basics, Dockerfile, and Docker Compose.

    • Explore container orchestration tools like Kubernetes for managing and scaling containerized applications.

  6. Continuous Integration (CI):

    • Set up a CI/CD pipeline using Jenkins, GitLab CI, or Travis CI.

    • Practice automating builds, tests, and deployments.

  7. Continuous Deployment (CD):

    • Explore continuous deployment practices and tools.

    • Understand blue-green deployments and canary releases.

  8. Monitoring and Logging:

    • Learn about monitoring tools like Prometheus and Grafana.

    • Understand logging systems like ELK (Elasticsearch, Logstash, Kibana) or alternatives.

  9. Collaboration and Communication:

    • Familiarize yourself with collaboration tools like Slack, Microsoft Teams, or similar.

    • Understand how to integrate these tools with your DevOps processes.

  10. Security:

    • Learn about DevSecOps and integrate security practices into your pipelines.

    • Understand basic security measures for Linux systems and applications.

  11. Cloud Services:

    • Gain proficiency in a cloud platform such as AWS, Azure, or Google Cloud.

    • Learn about cloud-native services and how to deploy applications in the cloud.

  12. Networking Concepts:

    • Understand networking concepts, including firewalls, load balancing, and DNS.

    • Explore tools like Nginx or HAProxy for load balancing.

  13. Stay Updated:

    • DevOps is a rapidly evolving field. Follow industry blogs, attend webinars, and participate in forums to stay informed about the latest trends and technologies.
  14. Hands-On Projects:

    • Apply your knowledge through hands-on projects. Set up a personal project or contribute to open-source projects.
  15. Soft Skills:

    • Develop soft skills such as communication, collaboration, and problem-solving. DevOps is not just about tools but also about culture and collaboration.


As we conclude our exploration of the fascinating world of DevOps, I hope you've enjoyed delving into its intricacies and insights. We've covered the roadmap and learned together, but remember, the journey is far from over.
