Internal Developer Platforms (IDPs) are revolutionizing the way developers work by automating repetitive tasks, standardizing workflows, and reducing the time spent on infrastructure management. This not only leads to increased productivity but also fosters a culture of collaboration, innovation, and growth within the team. In this article, we dive into the world of open-source solutions that help you elevate your development process, streamline workflows, and improve efficiency. In other words, these solutions put together can provide you with the benefits of an IDP.
While there are several SaaS products like Argonaut, there might be org specific needs because of which bespoke tooling is needed. In such cases, open-source solutions can be leveraged to build your IDP. In this article, we explore the tools that can be used to build an IDP.
By leveraging open-source software to build your IDP, you benefit from a vast community of developers and documentation. However, in reality, there is no plug-and-play OSS IDP and some assembly is required. Some of the reasons are:
- Unique requirements: Your organization’s requirements vastly differ from other organizations that use IDPs. Matching these features to feature would usually require building a custom solution or severely modifying an available OSS.
- Open-source solutions rely on community support. Therefore, ensuring there’s an active community or the resources required to keep it up-to-date is important.
- Integration challenges: It is unlikely to find open-source solutions that seamlessly integrate with your company's existing tools, technologies, and infrastructure. This could lead to additional time and effort spent on customizing and integrating the solutions into your IDP, which may not always be feasible. Some OSS tools also lack proper documentation and don’t offer support, which could make implementing them even more challenging and costly.
Tooling for an Internal Developer Platform
The minimal requirements for an effective Internal Developer Platform (IDP) are an effective IaC solution, GitOps tooling, and a service catalog. There can be several other tools, such as monitoring, databases, CI tools, and security, as a part of your IDP. These together help your dev team automate repetitive tasks and standardize workflows.
Here we explore popular tools in each of these categories, along with alternatives.
