Standardized Development Environments (SDEs) are transforming the onboarding process by providing pre-configured environments that minimize setup time and eliminate configuration drift. Companies like Uber and Stripe have successfully implemented SDEs, including DevPods and DevBoxes, which enable developers to start coding instantly and collaborate seamlessly. By leveraging in-repo configurations and Dev Containers, companies can simplify onboarding and maintain consistency across the team. SDEs also bridge the gap between local and production environments, ensuring that code works as expected in both environments. Companies can now boost developer velocity by adopting these best practices, but may require external solutions like Daytona to implement them effectively.
