Platform engineering’s most critical first decision

Launching a successful platform engineering project hinges on a fundamental choice: where to begin. Deciding whether to prioritise the backend or frontend during development can significantly influence the platform's long-term effectiveness and scalability. Experts in platform engineering often stress the importance of starting with the backend, where robust business logic can serve as the foundation for all subsequent features.  

Why the backend Is the logical starting point  

The backend of a platform, often called the core infrastructure, is the foundation that defines how developers interact with systems and tools. A well-architected backend enables flexibility, scalability, and seamless integration with multiple user interfaces. This core logic ensures that various interfaces—whether graphical, code-based, or command-line—can plug into the platform without compromising functionality.  

In contrast, frontend interfaces, while critical for user experience, are primarily designed for visualisation and interaction. They lack the capacity to implement complex infrastructure configurations, manage access control, or support scalable workflows. Starting with the frontend may yield a visually appealing result early on, but it risks creating rigid systems that are difficult to adapt as needs evolve.  

The risks of a frontend-first approach  

A front-end-first approach is often pursued to demonstrate quick wins, such as an appealing dashboard or a polished interface. While this strategy can generate early enthusiasm, it frequently results in challenges later. Attempting to build or retrofit critical backend logic into a system designed from the frontend often leads to inefficiencies, technical debt, and even project failures.  

To avoid these pitfalls, teams should focus on building a strong backend infrastructure first. This allows for greater flexibility to incorporate advanced features and accommodate the diverse workflows of enterprise-scale operations. Lessons from previous projects highlight the importance of learning from experienced engineers who emphasise backend-first development for its strategic advantages.  

The long-term benefits of backend-driven platforms  

Building a platform with a backend-first approach requires effort, but the long-term benefits outweigh the initial challenges. Platforms designed this way enable developers to work more efficiently by automating repetitive tasks and providing curated tools in a unified environment. These efficiencies allow teams to focus on creative and strategic work rather than searching for or configuring tools manually.  

Backend-first platforms are also inherently scalable, allowing organisations to grow and evolve without requiring major redesigns. Over time, these platforms can deliver significant returns on investment by streamlining workflows and enhancing operational efficiency.

A strategic approach for sustainable success  

Platform engineering is not a short-term project but a long-term initiative. A backend-first strategy ensures that the platform is built on a robust foundation capable of supporting various interfaces, workflows, and organisational needs. Teams should align their efforts with a clear vision for scalability and adaptability, recognising that the initial effort will pay off in sustained performance and reduced maintenance challenges.  

While starting with the backend might take more time initially, it sets the stage for a scalable, efficient, and effective platform that can grow alongside organisational needs.
