A Grain of Salt

Understanding Platform Engineering

· Teddy Aryono

Platform engineering has emerged as one of the most significant shifts in how organizations build and deliver software. Yet despite the buzz, there’s often confusion about what platform engineering actually entails, how it differs from related disciplines, and why it represents a fundamental rethinking of how we enable developer productivity.

This post establishes the foundation: what platform engineering is, what platforms fundamentally are, and why this matters for both engineering organizations and individual engineers.

What Is Platform Engineering?

Platform engineering is the discipline of building and maintaining internal developer platforms (IDPs) that enable development teams to self-serve infrastructure, tools, and workflows. At its core, it’s about creating the “golden paths” that make it easy for developers to ship software quickly and reliably, without getting bogged down in infrastructure complexity.

The fundamental insight is to treat your internal platform as a product, with developers as your customers. You’re abstracting away the complexity of cloud infrastructure, deployment pipelines, observability tools, and operational concerns into a cohesive, self-service experience.

Core Responsibilities

Platform engineers typically focus on:

Infrastructure abstraction - Building interfaces and tooling that hide complexity while providing flexibility. This isn’t about dumbing things down; it’s about providing the right level of abstraction for common use cases while maintaining escape hatches for edge cases.

Developer experience - Creating intuitive workflows for common tasks like deploying services, accessing databases, or setting up monitoring. The goal is to minimize cognitive load and time-to-value.

Self-service capabilities - Enabling teams to provision resources and deploy applications without tickets or manual intervention. This is non-negotiable; without self-service, you’re just ops with better tooling.

Standardization - Establishing patterns and templates that encode best practices. When done well, this reduces decision fatigue and increases reliability across the organization.

Integration - Creating cohesive workflows from disparate tools (CI/CD, monitoring, logging, secrets management). The platform becomes the glue that makes your toolchain feel unified rather than fragmented.

How Platform Engineering Differs from DevOps and SRE

While there’s overlap, each discipline has a distinct focus:

DevOps emphasizes culture and breaking down silos between development and operations. It’s primarily about organizational transformation and collaboration patterns.

Site Reliability Engineering (SRE) focuses on reliability, running production systems, and on-call responsibilities. SREs own service reliability and often operate at the application level.

Platform Engineering focuses on building the tooling and platforms that enable both DevOps practices and SRE goals. You might think of it as “DevOps for DevOps” - the infrastructure team that enables other teams to practice DevOps effectively.

The relationship is complementary rather than competitive. Platform engineers build the foundations that make DevOps culture practical and give SREs better tools for ensuring reliability.

What Actually Is a Platform?

Before going deeper into platform engineering, we need to answer a more fundamental question: what is a platform?

The term gets used loosely in technology, leading to confusion. Let’s establish a clear definition.

The Core Definition

A platform is a foundation of self-service APIs, tools, services, knowledge and support which are arranged as a compelling internal product. The distinguishing characteristic is self-service - platforms enable others to build things without needing the platform team’s direct involvement for every action.

More fundamentally: a platform is not the end product itself - it’s what enables others to create end products.

Consider these examples:

What Platforms Provide

Successful platforms typically offer:

Abstractions over complexity - They hide difficult details behind simpler interfaces. You call an API to provision a server; you don’t physically rack hardware or navigate a maze of cloud console screens.

Standardized capabilities - Common needs are productized. Need a database? Here are the approved options with monitoring and backups included. Need authentication? Here’s the service that handles it.

Automation - Repetitive tasks become automatic. Deployments, scaling, backups, monitoring setup all happen without manual intervention.

Guardrails - The platform encodes best practices and prevents common mistakes. You can’t accidentally deploy without health checks or expose a database to the internet.

Integration - Disparate tools work together coherently instead of requiring manual wiring. Your CI/CD system knows about your deployment targets, your monitoring system automatically tracks your services, your logging aggregates across all your applications.

The Self-Service Requirement

This deserves emphasis: if developers have to file a ticket and wait for someone to manually provision their database, that’s not a platform - that’s a bottleneck with tooling.

A true platform means:

The platform team builds and maintains the capability; product teams consume it on demand.

What Platforms Are Not

Clarifying by contrast helps:

Not just infrastructure - Having AWS accounts isn’t a platform. Raw infrastructure with no self-service layer is just infrastructure.

Not just tools - Having Jenkins and Terraform doesn’t mean you have a platform. Unintegrated tools that require expertise to use aren’t platforms.

Not just documentation - A wiki explaining how to manually set up services isn’t a platform. Documentation is necessary but not sufficient.

Not a service desk - If developers submit tickets and wait for ops to do things manually, that’s a ticketing system, not a platform.

A platform is when these elements come together into a coherent, self-service experience.

A Concrete Example: Deploying a Service

Let’s make this tangible with a real-world scenario: deploying a new web service.

Without a Platform

A developer needs to:

This might take days or weeks, requires deep infrastructure knowledge, and will be implemented differently by every team (no standardization, no consistency).

With a Platform

A developer:

  1. Runs platform create service my-api --runtime python --database postgres
  2. The platform generates a basic service structure
  3. Developer writes their application code
  4. Commits to Git
  5. Platform automatically: builds container, runs tests, deploys to staging, provisions database, configures monitoring, sets up logging, creates dashboards, configures auto-scaling, sets up alerts
  6. Developer reviews staging, merges to main
  7. Platform deploys to production with the same automation

This takes hours instead of weeks, requires minimal infrastructure knowledge, and is consistent across all teams.

The platform is everything that made that second scenario possible - the CLI tool, the APIs it calls, the automation pipelines, the monitoring setup, the database provisioning, the integration between all these pieces.

The Three Dimensions of Platform Engineering Success

Platform engineering success requires excellence across three interconnected dimensions:

1. Technical Excellence

Building robust, reliable abstractions that are genuinely easier than the alternatives. This includes:

Technical excellence alone isn’t sufficient - you can build the best platform in the world and have it fail if the organizational and cultural dimensions aren’t addressed.

2. Organizational Structure

Treating the platform as a product requires proper organizational support:

The platform needs executive sponsorship and must be recognized as foundational infrastructure, not a side project.

3. Cultural Investment

This is often the hardest part and where platform initiatives fail despite great technology:

Culture eats strategy for breakfast, and it eats platforms for lunch. A technically perfect platform that developers don’t trust or won’t adopt is worthless.

Why Platform Engineering Matters Now

Several factors have converged to make platform engineering essential:

Increasing Complexity - Modern applications span multiple clouds, dozens of services, complex networking, extensive compliance requirements, and sophisticated observability needs. The cognitive load on developers has become unsustainable.

Cloud Native Complexity - Kubernetes and cloud-native technologies are powerful but notoriously complex. Organizations need abstraction layers to make these technologies accessible to most developers.

Velocity Requirements - Business demands faster delivery. Platform engineering enables this by removing friction from the development workflow.

Talent Efficiency - Good developers are expensive and hard to find. Platform engineering multiplies their effectiveness by letting them focus on business logic rather than infrastructure details.

Reliability at Scale - As organizations grow, ad-hoc approaches to infrastructure don’t scale. Platforms encode reliability best practices consistently across all teams.

The Platform as Product Mindset

The most successful platform organizations embrace product thinking:

User Research - Interview developers, observe workflows, identify friction points. What takes them hours that should take minutes?

Product Metrics - Track adoption rates, time-to-deployment, developer satisfaction (NPS), support ticket volume.

Roadmaps and Versioning - Treat platform features like product features with clear release cycles, deprecation policies, and migration paths.

Documentation as First-Class - Your platform is only as good as its documentation. Invest heavily in tutorials, runbooks, and architecture decision records.

Feedback Loops - Regular office hours, internal user groups, champions networks, and open communication channels.

This mindset shift - from “we run infrastructure” to “we build products for internal developers” - is perhaps the most important aspect of platform engineering.

Layers of Abstraction

An interesting perspective: platforms build on platforms.

Your application runs on your internal platform, which runs on Kubernetes, which runs on AWS, which runs on physical infrastructure.

Each layer is a platform for the layer above. Each layer abstracts complexity and provides self-service capabilities to the next level up.

Your internal platform isn’t replacing Kubernetes or AWS - it’s adding a layer of organization-specific abstractions on top that encode your standards, integrate your tools, and match your workflows.

This layering is powerful because each layer can focus on its appropriate level of abstraction without trying to solve every problem.
