How do you scale a platform/DevOps team to support a growing engineering organization?

Sample answer

Scaling platform teams requires balancing self-service with support. Strategies: 1) Build internal platforms - abstract complexity, provide golden paths. 2) Self-service tooling - templates, CLIs, portals for common tasks. 3) Inner source model - development teams contribute back. 4) Documentation and training - reduce support burden. 5) Embedded vs centralized - consider platform engineers embedded in product teams. 6) Toil reduction - automate repetitive requests. 7) SLOs for internal services. Goal: platform team scales sub-linearly with company growth through leverage.

Why this matters

A platform team that must manually handle every request becomes a bottleneck. The modern approach treats internal developers as customers and builds products for them. Spotify's model, Backstage-style portals, and 'you build it, you run it' all aim to increase developer velocity while maintaining standards. Success is measured by developer satisfaction and ability to ship safely without waiting on the platform team.

Code examples

Backstage service template

yaml

apiVersion: scaffolder.backstage.io/v1beta3
kind: Template
metadata:
  name: microservice-template
  title: New Microservice
  description: Create a production-ready microservice
spec:
  owner: platform-team
  type: service
  parameters:
    - title: Service Info
      properties:
        name:
          title: Name
          type: string
        team:
          title: Owning Team
          type: string
          enum: [payments, users, orders]
  steps:
    - id: fetch
      action: fetch:template
      input:
        url: ./skeleton
    - id: publish
      action: publish:github
    - id: register
      action: catalog:register

Platform CLI example

bash

#!/bin/bash
# Internal platform CLI for self-service

# Create new service (templated)
platform create service --name payments-api --team payments

# Request database
platform request postgres --size medium --team payments

# Deploy to environment
platform deploy payments-api --env staging

# View service health
platform status payments-api

# Access logs (with proper RBAC)
platform logs payments-api --since 1h

Common mistakes to avoid

Building a platform nobody asked for (solution looking for a problem)
Not treating internal tools with the same rigor as customer-facing products
Forcing teams to use the platform instead of making it genuinely better

Likely follow-ups

How do you balance standardization with team autonomy?
What metrics do you use to measure platform team effectiveness?
How do you handle teams that want to use non-standard tools?

Internal Developer Platform Purpose

Your team keeps filing tickets for things like creating new services, setting up databases, and getting access to staging environments. Your CTO asks you to fix this. What would you build, and why?
