WSO2Con 2025 - How an Internal Developer Platform Lets Developers Focus on Code
Download as PPTX, PDF0 likes125 views
Cloud-native development often involves setting up infrastructure, managing security, and integrating services—tasks that take time away from coding. An internal developer platform (IDP) streamlines these complexities, enabling developers to focus on building business logic. This lab demonstrates how an IDP supports a hybrid development approach, where developers run some components locally while consuming cloud services seamlessly. Instead of manually configuring databases, authentication, or API gateways, they leverage platform capabilities for rapid iteration. We’ll walk through a real-world scenario where a developer: Onboards quickly with an architect-defined application structure. Develops in a hybrid environment, consuming cloud APIs, databases, and AI services while iterating locally. Uses Choreo-managed authentication without dealing with OAuth2 intricacies. Discovers and reuses microservices and APIs instead of rebuilding them. Debugs efficiently without deploying all dependencies locally. Ensures security and compliance automatically, catching vulnerabilities early. By the end, you’ll see how an IDP accelerates onboarding, enhances security, and simplifies cloud-native development—so developers can focus on building great applications instead of managing infrastructure.

- 8. Part 2: Developer Experience
- 9. What keeps you away from code ? Before you can start writing a single line of code, there’s a long list of setup tasks: 1. Setup build pipelines 2. Configure development environments 3. Finding dependent services and configure the application 4. Set up the local development environment with the dependencies 5. Think about network security 6. Dealing with multiple teams to get the application setup 9
- 11. 1. Create a New Project 2. Create the Accounts API 3. Create the Receipts API 4. Connect the Receipts API with OpenAI 5. Deploy the Accounts and Receipts APIs to the Dev Environment 6. Create the BFF API 7. Test Locally 8. Create the Web Application 9. Test the Application Key Steps in Developer Experience Setup 11

Editor's Notes
- #3: Key Messages in Order Platform Engineers build the platform based on the needs of your organization. It could be multiple environments and pipelines, which data center to deploy apps Custom CI and CD pipelines.. This Platform is built to serve the Developers and Architects Architects need to see the live architecture diagram of their applications Developers needs to have a self serviceable platform to do their development. 1. Platform Engineers Build with Passion Platform engineers love building platforms, utilizing various technologies across cloud and on-premise solutions. 2. The Real Goal: Serving Developers and Architects A platform is only successful if it meets the needs of developers and architects. If it doesn't, it will be rejected. 3. Building the Platform is Just the Beginning The first step is designing and setting up the platform, but its true value comes when developers can easily adopt and use it. 4. The Continuous Operational Journey Beyond building, platform engineers handle ongoing operational tasks to ensure reliability, scalability, and security.
- #7: Choreo is ready to use from day one—right after signing up. As platform engineers, we don’t need to build the entire foundation from scratch. Instead, what we do here is configure it to fit our organization's needs. This setup gives us complete autonomy to enforce security policies, governance rules, and best practices while ensuring developers have a seamless experience. In this lab, we'll walk through the key steps to tailor the platform—from setting up environments and pipelines to managing access, enforcing governance, and integrating external services.
- #13: **"Developers have successfully onboarded their applications, and now it's our responsibility as platform engineers to ensure these applications run securely and efficiently in a production-grade environment. To achieve this, we need to promote the application to a higher environment, monitor its performance through observability tools, and configure alerts to detect and respond to potential issues proactively. This ensures reliability, scalability, and a seamless experience for both developers and end users."**
