👋 Short Intro (Why I’m Writing This)
I’m currently learning DevOps and decided to learn in public by documenting my journey.
This blog is part of my DevOps 101 series, where I’m learning DevOps step by step from scratch.
This series is not written by an expert — it’s a beginner learning out loud, sharing:
- what I understand,
- what confuses me,
- and what I learn along the way.
The goal is to build consistency, clarity, and invite discussion.
📌 What This Blog Covers
In this post, I’ll cover:
- How software was built before DevOps
- The traditional Dev vs Ops workflow
- Problems caused by siloed teams
- Why releases were slow and risky
- Real pain points that led to DevOps
- Why DevOps became necessary (not optional)
This blog is about the problem, not the solution yet.

📚 Learning Notes
1. How Software Was Built Traditionally
Before DevOps, software teams usually worked like this:
- Developers wrote code
- Operations teams deployed and maintained it
- Both teams worked separately
- Communication happened very late
This model worked when:
- releases were rare
- software changed slowly
- systems were small
But as software grew, cracks started showing.
2. The Traditional Dev vs Ops Split
Let’s simplify roles:
Developers (Dev):
- write features
- push code
- move to the next task
Operations (Ops):
- deploy code
- manage servers
- keep systems running
The problem:
- Dev cared about speed
- Ops cared about stability
Their goals often conflicted.
3. “Works on My Machine” Problem
One of the most common issues:
“It works on my machine.”
Why this happened:
- Dev environment ≠ Production environment
- Manual setup steps
- No consistency across systems
Result:
- broken deployments
- wasted time
- frustration on both sides
4. Manual Deployments Everywhere
Deployments used to be:
- manual
- slow
- error-prone
- stressful
Typical deployment flow:
- copy files manually
- run commands by hand
- restart servers manually
- hope nothing breaks
This made deployments:
- risky
- rare
- scary
5. Slow and Infrequent Releases
Because deployments were risky:
- releases happened once in weeks or months
- bug fixes took long to reach users
- feedback cycles were slow
This slowed down:
- innovation
- learning
- business growth
6. Blame Culture Instead of Ownership
When things broke in production:
- Dev said: “It worked in my environment”
- Ops said: “The code is bad”
Instead of fixing systems:
- teams blamed each other
- trust decreased
- morale dropped
No one truly owned the system end-to-end.
7. Scaling Made Everything Worse
As applications grew:
- more users
- more servers
- more complexity
Traditional workflows didn’t scale:
- manual steps didn’t work anymore
- human errors increased
- downtime became expensive
Companies needed a better way.
8. Business Pressure Increased
Modern businesses demanded:
- faster feature delivery
- high availability
- minimal downtime
- quick rollback when things fail
The old model simply couldn’t keep up.
9. Summary of Core Problems
Traditional software delivery suffered from:
- siloed teams
- slow releases
- manual deployments
- environment inconsistencies
- lack of ownership
- poor communication
- high failure rates
These problems weren’t edge cases — they were common.
10. Why These Problems Couldn’t Be Ignored
Ignoring these issues led to:
- unhappy users
- lost revenue
- burned-out engineers
- unstable systems
This pain forced teams to rethink how software is built and run.
And that rethink led to DevOps.
✅ Key Learnings & Takeaways
- Traditional Dev vs Ops separation caused major problems
- Manual processes don’t scale
- Slow releases hurt both users and businesses
- Blame culture prevents improvement
- These real-world problems created the need for DevOps
Understanding the pain makes the solution clearer.
