🧠 While working as a DevOps and Cloud engineer, I have been constantly researching and reading documentation to solve various real-world infrastructure, networking, automation, integration, security, and other problems that I encounter. Over the years, I’ve personally compiled this collection from various GitHub repositories, LinkedIn shares, technical blogs, the official websites, and other reliable sources, and then archived them 📂.
🔎 You'll definitely find valuable resources (books, notes, interview questions, exam questions, cheat sheets, whitepapers, guides, hands-on, handbooks, etc.) about DevOps/DevSecOps Tools and Cloud Systems in here.
🤝 Instead of keeping this archive private, I’m sharing it to benefit the community. 🌐 It would be great if you could share it too, so it can reach more people like you. This archive is not just an eBook list; it is a curated library prepared for professionals, learners, engineers, and job seekers in the IT field.
This curated PDF library covers everything from Docker, Git, Mock Exams, Cloud / DevOps Interview Questions, AWS/Azure/GCP cloud fundamentals, to advanced topics like Kubernetes, Terraform, CI/CD tools, Scripting, Python, Databases, Operating Systems, Cloud Architecture, and more. Happy reading! ☕
📢 I will regularly add new resources to the repository and announce them on my LinkedIn account or my Medium account. ✏️ Don't forget to follow to be informed about new updates.
⭐ Also, thank you for giving stars to my GitHub. I hope they are useful to you. 🙏 I wish you growing success.
📚 Books in this repo and books from other GitHub repositories, LinkedIn shares, technical blogs, the official websites, and other reliable sources have been brought together in this article by me. I have indexed the cover pages, author, page count, and introductions. You can find PDF ebooks on DevOps, DevSecOps, SRE, CISO, and Cloud Computing in this article.
🎯 I recommend that you take a look. You'll definitely find valuable resources there. Happy reading! ☕
