As a beginner DevOps engineer, it can be overwhelming
DevOps is overwhelming because the internet won’t shut up.
As a beginner DevOps engineer, you’ll feel like you’re behind.
Because every week there’s:
- a new tool
- a new “platform”
- a new best practice
- and a new influencer telling you you’re doing it wrong
Here’s the reality:
You don’t need to know everything. You need a foundation that survives tool churn.
Below is the foundation — in the order I’d learn it.
1) Version control (Git) — non‑negotiable
If you can’t work comfortably with Git, you’re playing on hard mode.
Learn to:
- branch and rebase without fear
- open PRs that are readable
- resolve conflicts without panicking
- write commits that explain intent
If it isn’t in version control, it doesn’t exist.
2) Scripting + automation — make the computer do the boring parts
DevOps is automation. Not meetings.
Pick one scripting language and get dangerous:
- bash for glue
- Python for real automation
- PowerShell if you live in Windows land
Start automating:
- environment setup
- deploy steps
- log collection
- repeated “runbook” commands
If you do something twice, automate it the third time.
3) CI/CD — pipelines are your factory line
Don’t worship a specific tool.
Understand the primitives:
- build
- test
- package
- deploy
- promote
- rollback
Then learn one CI system end-to-end (GitHub Actions, GitLab CI, Jenkins — whatever your world uses).
Pipelines don’t guarantee quality. They guarantee consistency.
4) Cloud fundamentals — learn one cloud deeply
Pick AWS/Azure/GCP and stop bouncing.
Learn:
- networking basics (VPC/VNet, subnets, routes)
- IAM (least privilege, roles, policies)
- compute + storage fundamentals
- monitoring/logging basics
Cloud is just someone else’s computer.
But the blast radius is bigger.
5) Infrastructure as Code — treat infra like software
Terraform/CloudFormation/etc. are just ways to make changes repeatable.
Practice:
- plan/apply discipline
- modularization
- state management
- safe rollouts
ClickOps scales until the first audit or outage.
6) Collaboration + communication — your superpower is clarity
The best DevOps engineers don’t just “fix it.”
They:
- write clear incident updates
- make runbooks usable
- teach others how the system works
- reduce future pages
Use tools like Jira/Slack, sure — but the real skill is:
Explain what’s happening, what you’re doing, and what good looks like.
Final rule
Don’t chase the “tool of the week.”
Chase fundamentals:
- versioning
- automation
- safe deployments
- observability
- recovery
Everything else is implementation detail.
Walk on.
