DevOps, Deployment & Operations
Ship it โ and keep it alive at 2am.
Environments, CI/CD, containers, infrastructure as code, logging, metrics, tracing, error tracking, alerting, load testing, incidents, and disaster recovery. Everything between 'works on my machine' and 'runs reliably for real users.'
Lessons
- โ
Environments: Dev, Staging, Prod
Dev, staging, prod โ why they differ, and why mixing them up burns you.
- โ
Deployment Without Mystery
What actually happens on deploy โ build steps, artifacts, and going live calmly.
- โ
Config & Secrets in Production (12-Factor)
The 12-factor way: configuration and secrets that are safe in production.
- โ
CI/CD Pipelines
Automate test-and-deploy so shipping is boring, safe, and frequent.
- โ
Containers & Docker
'Works on my machine,' solved โ package your app with Docker.
- โ
Infrastructure as Code
Your servers as version-controlled files โ reproducible, reviewable infrastructure.
- โ
Observability: Logging
What to log, structured logs, and levels โ so you can see what your app is doing.
- โ
Observability: Metrics & Tracing
Metrics and tracing: know your system's health and follow a request end to end.
- โ
Error Tracking & Alerting
Find out before your users do โ error tracking and alerts that actually help.
- โ
Performance & Load Testing
Profile, load-test, and find the bottleneck before real traffic does.
- โ
Incidents & On-Call
When prod breaks at 2am: incident response and on-call without the panic.
- โ
Maintenance, Reliability & Disaster Recovery
Dependency hygiene, backups, disaster recovery, and keeping it alive for years.
- โ
Capstone: Localhost โ Monitored Production Service
Take an app from localhost to a monitored, CI/CD-deployed, observable production service.
