Recreate Deployment With this deployment pattern, you deploy a new version of your application and delete the existing version of the application....

Progressive Delivery In this post, we will be looking at what progressive delivery is, why it is important and how to do it. we will also compare it with a traditional deployment strategy often referred to as Big Bang Deployment.
