  • Options for release and deploymentBig Bang: New of changed service is deployed to ALL users in one operation.Fast but has increased risk of negative impact for failed release.Phased Approach: Partial deployment. Repeated to other areas as per schedule.Can be slow and create tension between departments.The Push Approach: Service is PUSHED to the target locations.In terms of deployment either Big Bang or Phased use the pushed approach, sincethe service may be delivered at a time not of the users choosing.The Pull Approach: Software is made available in a secure location and users mayPULL it down into their system at a time of their choosing.Automated: A automatic system delivers the release. This is often easily repeatable.Manual: often error prone and very slow. Created by PelegIT, Ltd. – www.pelegit.com, - All Rights Reserved
