Invent the Feature, Not the Platform: the business case for Platform Engineering

Access to powerful IT solutions has become a commodity. Developers can obtain platforms and services from numerous sources — AWS, Azure, GCP, Kubernetes, GitLab — and this accessibility should liberate them to focus on features and business value. However, this abundance of choice has created a new problem: tool and cognitive overload. Without standardisation, every team reinvents solutions for every use case, resulting in expensive, fragmented toolchains. Platform Engineering — an evolution of DevOps — solves this by delivering a platform developers can use without individuals needing to master both platform engineering and software development simultaneously.

Jack of all trades, master of none

DevOps aimed to unite development and operations, but the knowledge gap has grown too large for one person. Modern cloud infrastructure requires a level of expertise that matches the complexity of application code. Expecting a single engineer to master both domains creates an impossible cognitive load. Rather than forcing developers to wrestle with underlying machinery, organisations should provide a centralised layer that abstracts this complexity away.

A mindset that enables growth

Platform Engineering, as practised by high-performers like Spotify, builds an internal "platform as a service." This Internal Developer Platform (IDP) delivers three core values:

1. Self-service capabilities — developers obtain the resources they need immediately, without ticketing or waiting on another team.
2. Common, standardised tooling — approved, secure, and efficient "golden path" tools that everyone uses by default.
3. Standardised workflows — automated, repeatable processes for building, deploying, and observing software.

The benefits directly impact the bottom line: costs drop by eliminating redundant work, engineers focus on value-adding code, and proven approaches are standardised rather than supported in dozens of variants. This keeps architectural complexity and maintenance overhead low.

The strategic shift: treat your platform as a product

Nearly all use cases — except the most complex edge cases — are solvable with off-the-shelf tooling. The traditional reflex was to build a custom solution for each situation, assuming that unique optimisation was necessary. The modern, efficient approach standardises on a small number of proven methods, trading marginal optimisations for enormous real-world cost savings and the speed that comes from reliable, reusable solutions.

Invent the feature, not the tool

External products are built around standardised features that deliver a specific experience. Building fully bespoke systems for individual customers quickly becomes unaffordable — and internal platforms are no different. Treat your platform as a complete product, just like commercial software. Creating standardised, user-friendly, self-service workflows ensures the platform is actually usable by its developer customers. This standardisation enables faster value delivery, drastically reduces development and maintenance costs by focusing on a small number of key approaches, and allows you to change course effectively when the market demands it.

Where do you start

Treat internal infrastructure as a product and developers as genuine customers. Focus on the key "products" you want to offer them — think of it like building a quality webshop with clear products and a simple checkout. Tools like Backstage.io or similar developer portal solutions help create that developer-facing storefront. Build the underlying building blocks with industry-standard tools like Terraform to eliminate manual deployments and standardise solutions.
