From Friction to Flow

Enabling Collaboration and
Developer Experience at Scale

Niek Palm

How do you picture Philips?

Probably this?

Not this

Philips is a health technology company improving people's health and well-being through meaningful innovation

Our purpose is to improve people’s health and well-being. We aim to improve 2.5 billion lives per year by 2030

Software in Philips

• 8000+ software professionals

• Global organisation

• Regulated medical software

• 100s millions lines of code

Challenges

• Hard to collaborate
• Hard to start and deliver
• Hard to unlock new features
• Hard to automate common tasks

Adopting InnerSource

• Collaborate at Scale

• Build on top of GitHub (SaaS)

Enable InnerSource

• One source code platform

• InnerSource as default

• Control by the owning team

Atumation as a habit

• CI/CD a First-class citizen

• As easy as for Open Source

• But with enterprise needs

Enable CI/CD

with GitHub Actions

on: [push]
jobs:
  check-bats-version:
    runs-on: [ubuntu-latest]
    container: node:20
    steps:
      - uses: actions/checkout@v3
      - run: npx bats -v

But how can we connect

to our network?

hosted runners

self-hosted runners

Why self-hosted?

How to bring same DevX to self-hosted runners?

Manual?

Ask AI?

Event based

Scale based on workflow jobs

Serverless

low cost / low maintenance control plane

Treat as Cattle

Secure and no firefighting

Networking

Bring your own connection

Scalable self-hosted

Limits

Developer Experience

• Productivity - Am I enabled?
• Impact - Can I focus on my job?
• Statisfaction - Do I have the right environment?

Developer Portal

Build an ecosystem, not a wilderness

• Software Catalogus
• Bootstrap / Scaffolding
• TechDocs

Software Catalogus

⛭ Scaffolding / Automation

TechDocs

Enable via configuration

• Define software assets as code (catalog file)
• Enable plugins via annotation
• Default integrations enabled
• No extra development effort required

Contribution

• Open for extension via InnerSource
• Developer guide for extension
• Enable via DevContainers / CodeSpaces

also serverless

• ALB to enforce SSO login
• Fargate to serve Backstage
• OpenSearch to speed up searches
• S3 to serve TechDocs

Compliance

• Assist to do it right - scaffolding
• Avoid shadow IT - e.g. runners
• Continuous compliance - rule based
