Vagrant can be used to create consistent development environments that match production. This allows developers to develop locally yet still have access to all production dependencies. The presenter recommends using Vagrant to provision local development environments that match the OS used in production AWS environments. Developers can then use the same configuration management tools and processes locally and in production. Code is deployed from Vagrant environments to AWS, ensuring development and production remain consistent. A demo is provided to stand up identical local and AWS environments and deploy code between them.
