Premium IT & Linux eBooks for Professionals
Welcome to the Dargslan eBook library — a curated collection of 271+ practical digital books covering Linux administration, DevOps, cloud infrastructure, cybersecurity, Python programming, Windows Server, networking, and modern software engineering. Every title is hand-picked, reviewed for accuracy, and written by working engineers who use these tools every day in production environments. Whether you are preparing for a Red Hat, AWS, or Microsoft certification, hardening a Linux server, building a CI/CD pipeline, or learning a new scripting language, our catalog gives you battle-tested guidance you can apply immediately.
What makes our IT eBook collection different
Most online learning platforms lock content behind expensive monthly subscriptions or push outdated PDFs that were last updated years ago. We do the opposite: buy once, own forever, with free lifetime updates whenever a major edition is released. Every eBook ships in modern PDF and EPUB formats, is DRM-free, and works on any device — Linux, macOS, Windows, iPad, Kindle, or your favorite e-reader. Average price across the catalog is around €14, and we regularly offer curated bundles that drop the per-book price even lower.
Topics we cover in depth
- Linux & Unix: Bash scripting, systemd, package management, kernel internals, performance tuning, and distribution-specific guides for Ubuntu, Debian, RHEL, AlmaLinux, Arch, and Fedora.
- DevOps & SRE: Docker, Kubernetes, Terraform, Ansible, GitOps, CI/CD with GitHub Actions and GitLab, observability with Prometheus and Grafana, and incident response playbooks.
- Cloud Infrastructure: AWS, Azure, and Google Cloud architecture patterns, cost optimization, IAM hardening, serverless design, and multi-cloud strategies.
- Cybersecurity: Penetration testing, OSSEC, Wazuh, SELinux, AppArmor, network forensics, OWASP Top 10, secure coding, and Linux server hardening.
- Python & Automation: CLI tools, async programming, FastAPI, data engineering, infrastructure-as-code with Python, and AI/LLM integration.
- Windows Server & PowerShell: Active Directory, Group Policy, PowerShell automation modules, and hybrid Windows/Linux administration.
