“100 Days of DevOps” is a concept that involves dedicating 100 days to learning and practicing various aspects of DevOps methodologies. DevOps is a set of practices that aims to automate and integrate the processes between software development and IT operations, with the goal of delivering high-quality software quickly and reliably. The “100 Days of DevOps” challenge is often undertaken by individuals or teams who want to immerse themselves in DevOps principles, tools, and practices.

During the 100 days, participants typically engage in a variety of activities, such as:

1. Learning: Spending time each day to study and understand the key concepts of DevOps, including continuous integration, continuous delivery, infrastructure as code, automation, monitoring, and more.

2. Hands-On Practice: Actively working on real-world projects or exercises that involve implementing DevOps practices. This could include setting up CI/CD pipelines, automating infrastructure provisioning, and configuring monitoring and alerting systems.

3. Tool Exploration: Exploring and becoming proficient with popular DevOps tools, such as Jenkins, GitLab CI/CD, Docker, Kubernetes, Ansible, Terraform, Prometheus, Grafana, and more.

4. Collaboration: Embracing collaboration and communication between development and operations teams to break down silos and ensure smooth workflows.

5. Continuous Learning: Keeping up with the latest trends and updates in the DevOps space by reading blogs, watching videos, attending webinars, and participating in online communities.

6. Reflection: Taking time to reflect on what has been learned and achieved during the challenge, and identifying areas for improvement.

7. Adapting and Iterating: Adjusting the learning plan and activities as needed based on insights gained during the challenge.

The “100 Days of DevOps” challenge is not a strict program with a fixed curriculum, but rather a flexible approach that encourages participants to tailor their learning journey to their own goals and needs. It’s important to set achievable goals and gradually build up skills over the 100-day period.

Keep in mind that DevOps is a vast field, and the challenge may only scratch the surface of what’s possible. The primary goal is to develop a solid foundation in DevOps practices and principles while fostering a continuous learning mindset.
