Why Platform Engineering Teams Are Building Internal Developer Portals

Developers rarely complain about having to write code; what they do complain about, however,t is everything else surrounding it. That includes figuring out the right deployment template, requesting access to infrastructure, waiting for platform teams, navigating security requirements, and the list goes on. As organizations grow their cloud-native ecosystems, the complexity of software delivery often grows faster than a dev team can keep up with. Internal Developer Portals are emerging as one solution to all these problems.

What started as a simple way to improve developer experience has now become a cornerstone of platform engineering. Many companies are using an internal portal to streamline workflows, offer self-service to infrastructure, apply policy, and remove bottlenecks while not impacting developer velocity.

Solving the complexity problem

Today’s software delivery is powerful but very fragmented. Software developers working on a new service might need to engage with Kubernetes, CI/CD, observability, security tools, cloud infrastructure, service mesh, secrets management, and internal policies. Each system introduces its own documentation, interfaces, and operational requirements. The result is often a terrible developer experience.

Developers spend hours trying to find what they need to find, asking for permission or guidance, figuring out how to deploy, or finding out which team owns a particular service. When companies adopt a microservices architecture, the problem is even worse because more and more services are typically added to the mix. That’s one of the main reasons why platform engineering emerged: to create platforms and tools that simplify the dev workflows. Internal developer portals have become one of the primary interfaces through which those tools are delivered.

A single entry point

Internal Developer Portals give developers a single interface for all their software delivery needs. Instead of digging through multiple documentation sites, cloud UIs, ticketing systems, CI/CD consoles, and infrastructure tools, all this information can be accessed from one location.

Internal Developer Portals are useful, in part because they solve a really common problem: discoverability! Many dev teams have tools to meet their needs. It’s just that developers don’t always know about those tools or how to use them correctly. An internal portal helps bring service catalogs, deployment instructions, documentation, ownership data, operational dashboards, and templates into one place.

This type of system was popularized by Backstage, which was created at Spotify and recently moved to the Cloud Native Computing Foundation (CNCF). Today, Backstage is one of the top choices for companies to use for internal developer portals to manage things like service inventories or deployment automation.

Self-service is the real goal

In addition to discoverability, Internal Developer Portals are often used for enabling self-service. In many companies, developers still have to go through some sort of platform or operations team to ask for an environment to be provisioned, infrastructure resources to be created, deployments configured, or new services onboarded. These sorts of requests will often involve a ticketing system and multiple stages, approvals, and handoffs before work can even start. That isn’t scalable.

With an Internal Developer Portal, you can expose workflows that have been pre-approved for self-service use without a human platform engineer directly involved in the process. This means less downtime, which leaves the platform team free to work on the platform rather than dealing with operational support requests.

Golden paths reduce friction and improve consistency

An important concept in modern platform engineering is the idea of a “golden path.” A golden path describes the recommended approach for developers in building, deploying, and operating applications. Instead of having to reinvent the wheel for each team, the platform engineers provide pre-approved templates, patterns, and deployment workflows that represent best practices in that organization.

These paths are typically exposed through an Internal Developer Portal. As opposed to having to build these parts from scratch themselves, developers are now presented with a production-ready baseline. This helps maintain consistency across multiple deployments as well as reduces the number of choices a developer must make.

It’s worth emphasizing that a golden path isn’t intended to be restrictive; developers may, when needed, choose a custom approach, but this one path is made as simple as possible.

Governance without bottlenecks

For decades, governance has been one of the biggest causes of friction in delivering software. While security reviews, compliance checks, operational policies, and infrastructure standards are necessary in any production environment, if not implemented carefully, they can slow down development significantly. Internal Developer Portals can help overcome this challenge by providing a way to embed governance directly into the development platform. In many cases, if developers build on top of the pre-approved templates, then a lot of governance checks can happen automatically as part of a template.

Security controls, policy enforcement, resource standards, and compliance reviews now all happen as part of the workflow as opposed to manual, external gateways. This approach is similar to trends such as “policy-as-code”, GitOps, and platform engineering, which all seek to automate and thus embed controls into the software development pipeline.

The business value of improving developer experience

One key benefit of an Internal Developer Portal is the improvement in the developer experience, a major focus of platform teams today. Developer productivity is increased because developers spend less time waiting for support or figuring out how to perform common tasks, making it easier to discover operational tools, find service documentation, or determine who owns a given service. All of these improvements might seem relatively small and insignificant on their own, but together they make a major difference.

Reducing just a small fraction of developer friction can add up across an entire organization with hundreds of developers. This is one of the reasons why developer experience is often an important success metric in platform engineering, alongside other standard metrics like reliability and platform performance, of course.

IDPs are becoming platform operating systems

In conclusion, the function of an IDP continues to evolve from its origins as a documentation and service catalog. Today, an Internal Developer Portal is often the primary interface for platform engineering. This is now a crucial layer in the growing complexity of cloud-native environments. Developers want an easy-to-use platform. Platform teams want consistency. Security teams want compliance. An IDP helps deliver all these benefits without having to trade one for the other.
