90DaysOfDevOps

Product Introduction

1. Definition: 90DaysOfDevOps is an open-source, multi-year structured learning repository and technical curriculum designed to teach modern Development and Operations (DevOps) engineering principles, continuous integration/continuous deployment (CI/CD) pipelines, infrastructure as code (IaC), and cloud-native tooling. Operating within the developer education and technical upskilling category, it provides a day-by-day roadmap for mastering the DevOps toolchain.
2. Core Value Proposition: It exists to eliminate the analysis paralysis and information overload inherent in the vast, rapidly evolving cloud-native technology landscape. By offering a curated, step-by-step DevOps learning path, it accelerates time-to-competency for engineers transitioning into cloud engineering, site reliability engineering (SRE), and platform engineering roles without requiring expensive bootcamps or disorganized self-directed research.

Main Features

1. Structured Day-by-Day Curriculum: A linear, highly organized modular learning path spanning fundamental concepts to advanced architectures. It works by breaking down monolithic technical domains—such as Linux, networking, Git, CI/CD, and monitoring—into digestible daily tasks, hands-on labs, and reading materials, leveraging GitHub Markdown for version-controlled documentation and community contributions.
2. Comprehensive Cloud-Native Toolchain Integration: Practical, scenario-based tutorials covering industry-standard technologies. It covers Git for version control, GitHub Actions and GitLab CI for automation, Terraform and Ansible for Infrastructure as Code and configuration management, Docker and Kubernetes for containerization and orchestration, and Prometheus and Grafana for observability and monitoring.
3. Open-Source Community Collaboration: A crowdsourced, continuously updated knowledge base driven by industry professionals. It functions via GitHub issues, pull requests, and discussions, ensuring the curriculum adapts in real-time to emerging Cloud Native Computing Foundation (CNCF) tools, security best practices (DevSecOps), and shifts in enterprise infrastructure requirements.

Problems Solved

1. Pain Point: The steep learning curve and fragmentation of resources in the DevOps ecosystem, which often leaves self-taught engineers overwhelmed by conflicting tutorials, outdated documentation, and a lack of structured guidance on where to begin.
2. Target Audience: Software developers transitioning to infrastructure roles, system administrators modernizing legacy skill sets, computer science graduates entering cloud engineering, and technical managers seeking a standardized internal training roadmap for junior engineers.
3. Use Cases: Self-paced career pivoting into Site Reliability Engineering (SRE), upskilling enterprise development teams on containerization and Kubernetes orchestration, and serving as a reference syllabus for university or corporate tech training programs.

Unique Advantages

1. Strengths & Limitations (Pros & Cons):
   • Pros: Completely free and open-source; highly practical with real-world tooling focus; community-vetted updates that reflect current industry standards; structured eliminates planning fatigue.
   • Cons: Requires high self-discipline due to its self-paced nature; lacks interactive in-browser lab environments (requires users to provision their own cloud accounts or local virtual machines); can move rapidly, occasionally requiring supplementary documentation for deep troubleshooting.
2. Key Alternatives & Differentiation:
   • A Cloud Guru / Pluralsight: Commercial video-based subscription platforms. Unlike 90DaysOfDevOps, which is text-based, free, and GitHub-native, these alternatives offer video lectures and sandbox environments at a monthly cost.
   • KodeKloud: Interactive lab-centric platform. While KodeKloud provides hands-on terminal sandboxes, 90DaysOfDevOps excels as a comprehensive, holistic syllabus that connects the broader architectural narrative across multiple disparate technologies.
   • Roadmap.sh (DevOps Roadmap): A visual branching guide. While Roadmap.sh tells you what to learn, 90DaysOfDevOps provides the actual curated content, labs, and daily breakdown of how to learn it.

Frequently Asked Questions (FAQ)

1. What prerequisites are needed before starting 90DaysOfDevOps? A foundational understanding of basic command-line operations, basic networking concepts (TCP/IP, DNS), and general familiarity with programming or scripting languages (such as Python or Bash) will help learners keep pace with the technical labs.
2. Is 90DaysOfDevOps completely free to use? Yes, the 90DaysOfDevOps repository is hosted openly on GitHub under an open-source license, allowing anyone to access, fork, and utilize the curriculum at no cost.
3. How long does it actually take to complete the 90DaysOfDevOps curriculum? While the syllabus is structured around a 90-day framework, working professionals or complete beginners often take anywhere from 3 to 6 months to thoroughly complete the hands-on labs, depending on their prior IT experience and daily time commitment.
4. Does 90DaysOfDevOps cover Kubernetes and Cloud Providers? Yes, the curriculum dedicates significant modules to container orchestration with Docker and Kubernetes, as well as deployment strategies across major cloud service providers like AWS, Azure, and Google Cloud Platform.
