Platform Engineering: Building the Foundation for Modern Software Development

Platform engineering is the discipline of designing and building toolchains and workflows that enable self-service capabilities for software engineering organizations. Think of it as creating a well-organized workshop where developers have all the tools they need at their fingertips.

This article will explore what platform engineering is, why it matters, how it works, and how organizations can implement it effectively.

What is Platform Engineering?

Platform engineering is the practice of designing and maintaining a platform that provides developers with the tools, services, and infrastructure they need to build, test, and deploy applications efficiently.

Key Components of Platform Engineering

• Infrastructure: The underlying hardware and software resources
• Tooling: Development and operational tools
• Automation: Processes that reduce manual work
• Self-service: Capabilities that allow developers to help themselves
• Documentation: Clear guides and references

Why Platform Engineering Matters

Platform engineering addresses several critical challenges in modern software development:

Accelerating Development Cycles

Traditional development processes often involve lengthy approval chains and manual configurations. Platform engineering creates streamlined pathways that reduce these bottlenecks.

Reducing Cognitive Load

Developers can focus on writing code rather than understanding complex infrastructure details. The platform abstracts away complexity while providing necessary guardrails.

Improving Consistency

With standardized tools and processes, teams across an organization can work more cohesively, reducing integration issues and improving overall quality.

Enhancing Scalability

Well-designed platforms can grow with the organization, supporting more teams, applications, and users without proportional increases in overhead.

The Evolution of Platform Engineering

Platform engineering didn’t emerge in a vacuum. It evolved from several preceding practices:

From Traditional Operations to DevOps

Traditional IT operations involved separate teams managing infrastructure and applications. DevOps brought these together, emphasizing collaboration and shared responsibility.

From DevOps to Platform Engineering

While DevOps improved collaboration, organizations still struggled with consistency and scalability. Platform engineering builds on DevOps principles by creating standardized, reusable platforms.

Core Concepts in Platform Engineering

The Paved Road Concept

The “paved road” is a central metaphor in platform engineering. It represents the recommended, supported path for development tasks.

• On the paved road: Developers have access to supported tools, templates, and processes
• Off the paved road: Teams can still innovate, but with less support and more responsibility

This approach balances standardization with flexibility.

Product Thinking for Internal Platforms

Platform engineering treats internal platforms as products, with:

• Users: The developers who use the platform
• Features: The capabilities and services provided
• Feedback mechanisms: Ways to improve based on user experience

API-First Design

Modern platforms expose functionality through APIs, enabling:

• Consistent access to resources
• Integration with various tools
• Automation of workflows

Platform Engineering in Practice

Common Platform Components

Development Environments

Consistent, reproducible environments that can be quickly provisioned:

# Example of a simple development environment definition
apiVersion: v1
kind: Namespace
metadata:
  name: dev-environment
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: app-deployment
  namespace: dev-environment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: app-container
        image: my-app:latest
        ports:
        - containerPort: 8080

CI/CD Pipelines

Automated workflows for building, testing, and deploying code:

# Example of a simple CI pipeline
name: Build and Test
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v2
    - name: Setup Node.js
      uses: actions/setup-node@v2
      with:
        node-version: '14'
    - name: Install dependencies
      run: npm install
    - name: Run tests
      run: npm test
    - name: Build application
      run: npm run build

Observability Tools

Monitoring, logging, and tracing capabilities that provide insights into application behavior.

Security Scanning

Integrated tools that identify vulnerabilities in code and dependencies.

Platform Team Structure

Successful platform engineering requires the right organizational structure:

Centralized Platform Team

A dedicated team responsible for building and maintaining the platform. This approach ensures consistency but can become a bottleneck if not properly resourced.

Embedded Platform Engineers

Platform specialists embedded within development teams. This provides context-specific support but may lead to fragmentation.

Hybrid Approach

A central platform team that defines standards and builds core capabilities, with embedded engineers handling team-specific needs.

Implementing Platform Engineering

Starting Your Platform Engineering Journey

1. Understand Your Users

Before building anything, identify your users’ needs:

• What are their biggest pain points?
• What tools do they currently use?
• What would make them more productive?

2. Define Your Platform’s Scope

Start small and expand gradually:

• Begin with the most common needs
• Establish clear boundaries for what the platform will provide
• Create a roadmap for future capabilities

3. Measure Success

Define metrics to track your platform’s effectiveness:

• Developer satisfaction scores
• Time to provision environments
• Deployment frequency
• Change failure rate

Common Challenges and Solutions

Challenge: Adoption Resistance

Developers may resist using a new platform, especially if they feel it limits their flexibility.

Solution:

• Involve developers in the platform design process
• Clearly communicate the benefits
• Provide excellent documentation and support
• Start with volunteer teams to build success stories

Challenge: Maintaining Balance

Finding the right balance between standardization and flexibility can be difficult.

Solution:

• Implement the paved road concept
• Allow for exceptions with clear guidelines
• Regularly review and adjust based on feedback

Challenge: Demonstrating Value

Platform engineering benefits can be indirect and hard to measure.

Solution:

• Track metrics that matter to the business
