Internal Developer Platforms: Key Components and 5 Solutions to Know

What Are Internal Developer Platforms (IDP)?

Internal Developer Platforms (IDPs) are centralized self-service platforms that provide development teams with the tools, environments, and frameworks they need to build, deploy, and manage applications efficiently. Built as internal products, they are designed to streamline and standardize the software development lifecycle (SDLC), from coding to deployment, per particular company policies and objectives

IDPs serve as a bridge between the development and operations teams by abstracting infrastructure complexities and enabling developers to focus on writing code. They integrate various development and operations tools into a unified interface, allowing for a more streamlined development process.

IDPs support practices such as continuous integration/continuous deployment (CI/CD), infrastructure as code (IaC), and DevOps, making it easier for teams to adopt these methodologies.

Why Is an Internal Developer Platform Important?

An internal developer platform reduces complexity by abstracting away the underlying infrastructure and automating repetitive tasks. It boosts developer productivity and enhances job satisfaction by removing frustrating and time-consuming bottlenecks from the development process.

An IDP also helps ensure consistency. By providing a consistent development environment, IDPs manage tasks like software deployment and container orchestration, leading to faster release cycles and higher quality software.

IDPs aid in enforcing best practices and compliance across development projects. They ensure that applications are built and deployed in a consistent, secure, and scalable manner, thereby reducing the risk of errors and vulnerabilities. The use of an IDP leads to more reliable and maintainable software.

Internal Developer Platform vs. Internal Developer Portal

An internal developer platform is a toolset that streamlines the software development lifecycle by automating deployments and managing infrastructure. It’s an active platform that developers use to execute tasks and manage workflows.

An internal developer portal acts as a central repository for development resources, documentation, and tools. It’s a dynamic resource where developers can find information, access APIs, and learn about best practices. While the portal offers access to tools and services, it doesn’t automate workflows or manage infrastructure like an IDP.

Components of IDPs

An IDP typically includes the following components and capabilities. See for example the CNCF Platforms reference architecture.

Integration with Existing Tools and Services

The platform’s integration capability allows development teams to leverage their existing investments in tools for version control, continuous integration, and monitoring. It eliminates the need to switch between different tools and platforms, creating a seamless workflow.

By integrating with a wide range of tools and services, the IDP can provide a flexible environment. For example, if a team uses Kubernetes for orchestration, Jenkins for CI/CD, and Prometheus for monitoring, the platform can bring these disparate tools together in a cohesive ecosystem.

Application and Infrastructure Management

An IDP offers a unified interface for managing the application lifecycle and the underlying infrastructure, simplifying operations for developers and ops teams. This includes provisioning resources, configuring networks, managing storage, and scaling applications in response to demand. Developers can deploy applications without needing deep expertise in infrastructure.

Many IDPs incorporate infrastructure as code (IaC) principles, allowing teams to define their infrastructure through code, which can be versioned, reused, and shared. This approach enhances consistency and repeatability across environments, resulting in faster deployment, improved reliability, and greater agility.

Developer Self-Service Capabilities

The platform enables developers to perform tasks such as provisioning environments, deploying applications, and accessing resources without waiting for operations teams. This reduces bottlenecks and gives team members autonomy. Developers can experiment with new ideas, iterate quickly, and deliver features faster.

Self-service capabilities also promote a deeper understanding of the operational aspects of software development. This encourages developers to take ownership of their applications from development to production.

Collaboration and Governance

IDPs create a collaborative environment that encourages transparency, faster feedback loops, and more effective problem-solving. It also supports governance by enforcing policies, standards, and best practices across the development lifecycle. This ensures compliance with security, regulatory, and architectural requirements.

Governance features in IDPs can include role-based access control, auditing capabilities, and automated policy enforcement. These features help organizations maintain control over their development processes and infrastructure.

Build Your Internal Developer Platform with Spot by NetApp

Spot by NetApp’s optimization portfolio provides resource optimization solutions that can help make your IDP more impactful. Here are some examples of automated actions our users enjoy on their K8s, EKS, ECS, AKS and GKE infrastructure:

Autoscaling: This single word encompasses multiple procedures: knowing when to scale up or down, determining what types of instances to spin up, and keeping those instances available for as long as the workload requires. EC2 ASG’s are an example for rigid, rule-based autoscaling. You might want to get acquainted with additional K8s autoscaling methods like HPA or event-driven autoscaling.
Automated rightsizing: Recommendations based on actual memory and CPU usage can be automatically applied to certain clusters or workloads
Default shutdown scheduling: Requested resources can be eliminated after regular office hours, unless the developer opts out a specific cluster.
Automated bin packing: Instead of having nine servers 10% utilized, gather those small workloads in one server. Bin packing can be user-specific or not, according to your security policies.
Dynamic storage volume: Your IDP should regularly remove idle storage. It’s also recommended to align attached volume and IOPS with node size to avoid overprovisioning in smaller nodes.
AI-based predictive rebalancing replaces spot machines before they’re evicted involuntarily due to unavailability.
Data, network, and application persistence for stateful workloads, either by reattachment or frequent snapshots.
Dynamic resource blending aware of existing commitments (RIs, SPs) which must be used before purchasing any spot or on-demand machines.
“Roly-poly” fallback moves your workload to on-demand or existing commitments if there is no spot availability. When spots are once again available, you want to hop back onto them.
