AWS + Linux Combo — Part 11
CI/CD & Deployment Thinking
This part explains how code moves from laptop
to production safely and repeatedly.
This is where engineers become DevOps-minded.
What Is CI/CD?
- CI — Continuous Integration
- CD — Continuous Deployment
It means:
- Code is tested automatically
- Deployments are repeatable
- Human errors are reduced
Basic Deployment Flow
- Developer pushes code
- Pipeline runs tests
- Build is created
- Server pulls new version
Why Manual Deployments Fail
- Forgotten steps
- Wrong commands
- Inconsistent environments
Linux Role in CI/CD
Linux servers execute:
- Build scripts
- Deployment scripts
- Service restarts
Simple Deployment Example
git pull origin main
npm install
pm2 restart app
Automation replaces panic.
Real Engineer Mindset
If deployment scares you,
your system is fragile.
Strong systems make deployments boring.
