43 43  The following consideration are valid when upgrading to a new Cloud template

45 45  1. Service affecting vs. non-service effecting
46 -Non-service affecting templates will not affect your current operation * flows will continue to function as usual. You can safely apply the cloud template. Service affecting means that that the machines will need to be stopped and started to make the cloud template operational. There is short window in which flows are not operational and there will be a delay in message delivery & processing. Messages is not lost.

56 56  It is a good practice to isolate the Cloud template upgrade from these changes to the AWS slot. All changes can be handled in a single push of the button, but when an issue occurs at that moment it may become harder to isolate the root cause. So keep your Deploy Architecture as current as possible.

63 -For fail-over setups, the Cloud template upgrade will perform the upgrade zone by zone. There are 2 zones (A and B) defined in the failover scenario. Effectively this means that there is no downtime in the entire environment as flows and the JMS server will continue to operate as usual.
