2. Life before DevOps

Before DevOps came into picture, software development, operations, QA, Security used to work in a completely different way. Teams were separate, processes were slow, and delivering software felt like a long, painful journey. This older way of working is generally called traditional IT model or pre-DevOps era.

1. Everyone worked in silos​

  • Developers sat on one side, operations on another side.

  • They had very less communication.

  • Developers wrote code and threw it to Ops saying “it works on my machine.”

  • Ops team struggled to run the same code in production.

Result: misunderstandings, delays, and finger-pointing.

2. Manual work everywhere​

  • Code deployment was manual

  • Server setup was manual

  • Configuration was manual

  • Testing was manual

Everything required human effort. This meant more mistakes, more rework, and slow delivery.

3. Slow and big releases​

  • Companies used to release software once in 3 months, 6 months, or even 1 year.

  • Releases were huge, risky, and stressful.

On release day:

  • Teams used to work overnight.

  • Small issues became big failures.

  • Rolling back was very difficult.

4. No continuous feedback​

  • Developers had no idea how their code behaved in production.

  • Ops team didn’t know the intention of developers.

So, problems were discovered very late, sometimes after end-users complained.

5. Testing happened at the end after deployments​

  • Testing teams got the software at the last stage.

  • Bugs came very late in the cycle.

  • Fixing late issues took more time and increased cost.

6. Release days were full of stress​

  • Teams were afraid of deployments.

  • Many people stayed awake the whole night to deploy code.

  • A single wrong command could take servers down.

There was no automation or safety net.

7. Scaling was hard​

If customer traffic increased:

  • Ops team manually added servers.

  • Configuration mismatched.

  • Systems failed under load.

There was no concept of auto-scaling or container orchestration.

8. Blame culture was very common​

When something went wrong:

  • Developers blamed Ops.

  • Ops blamed Developers.

  • Testing team blamed both.

Teams were not aligned to one common goal.

9. No shared responsibility​

  • Developers cared only about writing code.

  • Ops team cared only about keeping systems stable.

  • QA was busy only with testing.

Nobody was responsible for the end-to-end product.

10. Tools and processes were not standard​

Each team used their own tools:

  • Dev used one tool

  • Ops used another

  • QA used something else
