🛠️ DevOps & SRE Journey: From High School to Expert Mastery (2025 Edition)

Welcome, future DevOps/SRE trailblazer! DevOps and Site Reliability Engineering (SRE) are your mission to streamline software delivery and ensure system reliability, powering platforms like Netflix or Google. DevOps bridges development and operations with automation, while SRE applies software engineering to operations for scalability and uptime. This roadmap guides you from a 10th/12th-grade beginner to an entry-level DevOps/SRE engineer and beyond to mastery. Expect a 12-24 month journey (part-time; 8-12 months full-time), with hands-on projects, a GitHub portfolio, and 2025-relevant skills like GitOps, cloud-native, and AI-driven operations. Let’s build unstoppable systems! 🚀

🌟 What are DevOps & SRE?

  • DevOps: A culture and practice combining development (Dev) and operations (Ops) to automate and accelerate software delivery using CI/CD, IaC, and collaboration.
  • SRE: Applies software engineering to operations, focusing on reliability, scalability, and performance (e.g., 99.99% uptime). Think DevOps with a reliability-first mindset.
  • Key Areas: CI/CD pipelines, infrastructure as code (IaC), monitoring, containerization, cloud ops. In 2025, trends include GitOps, AIOps (AI-driven operations), serverless DevOps, and multi-cloud strategies. Workflow: Plan → Automate → Deploy → Monitor → Optimize.

🔮 Future Scope
