Immutable infrastructure with Boxfuse
The document discusses immutable infrastructure with a focus on Boxfuse, a tool for implementing such infrastructure by creating and deploying minimal machine images. It contrasts immutable infrastructure with traditional methods, emphasizing its advantages in agile development and deployment. Key takeaways promote the regeneration of infrastructure after changes and suggest that Boxfuse is a viable solution for developers transitioning to immutable practices.
