The development environment is a personal digital workshop where developers spend most of their time creating, testing, and refining code. It's essential to standardize the development environment to ensure consistency across the company's development process, share code, collaborate effectively, reduce errors, and bring development velocity to the highest level. Standardized Development Environments (SDEs) are crucial for ensuring consistency in system-wide packages, IDE configurations, and compute resources. Docker is a widely adopted standard that enables developers to configure their environment with ease. Dev Containers and Devfile offer additional standards for container-based and Kubernetes-native environments, respectively. Nix provides a purely functional package manager that treats packages as immutable values, solving the "it works on my machine" problem. The choice of standard largely depends on project requirements, and it's essential to understand how each standard operates to choose the right one.
