DevOps Engineer interview question · Most asked

What is platform engineering, and how does it relate to DevOps?

Summary

Platform engineering builds an internal developer platform: self-service, paved-road tooling (service templates, CI/CD, environments, observability, secrets, infrastructure modules) operated as a product for internal developers, so product teams can ship and run software without each becoming experts in every tool. It is a way to scale DevOps practices across many teams.

Longer Answer

"You build it, you run it" can overload product teams with infrastructure complexity; a platform team reduces cognitive load by offering good defaults and abstractions while keeping teams autonomous. Success factors: treat developers as customers (research, feedback, adoption metrics), make the golden path the easiest path rather than mandatory, document well, and avoid building a ticket-driven operations team under a new name. Developer portals such as Backstage often front the platform.

Key Points

  • Internal developer platform as a product.
  • Self-service golden paths.
  • Reduces cognitive load on product teams.
  • Measure adoption and developer experience.
