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.

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
