Practical learning path
Start deploying with confidence
Learn each layer of a production system before adding automation. Every stage links to a practical guide and a clear outcome.
Linux fundamentals
Learn how to investigate memory pressure, processes, services, and logs on a VPS.
VPS networking
Understand deployment boundaries, ports, registries, and safe server access.
Nginx and HTTPS
Put a private application behind a domain with a reverse proxy and TLS.
Docker and Compose
Package applications and supporting services into repeatable environments.
CI/CD and operations
Automate deployments, monitor system health, and prepare for recovery when something fails.
Practice safely
Use a staging server or virtual machine while learning. Read every command, keep backups, and never make an irreversible production change without a rollback plan.
