Jfokus 2015 - Immutable Server generation: the new App Deployment
6 likes1,676 views
The document discusses the concept of immutable server generation for app deployment, emphasizing the importance of treating servers as disposable units similar to applications. It critiques traditional deployment practices that dictate building environments per server and advocates for a standardized automated approach to server management. The summary concludes with a call to action for adopting practices that promote regeneration of servers after every change, thus enhancing efficiency and reducing errors.
