How do you handle things like connection strings etc. Obviously a move off an App from one server to the next will break the connection as it gets a new IP. What are the best practices you recommend?

Depending on the application, there may be some changes required to use a VAA when it is moved to a new machine, such as specifying a unique IP address. AppZero has features to support this type of activity including network identity settings and full scripting capabilities if custom changes are necessary.

Two features we support are the ability to move a dedicated IP address with a VAA to a new machine, as well as the ability to dynamically specify an IP address to be used by a VAA. However, in the case where the IP address needs to change and configuration files need the new address, a script would generally be used to do a search and replace in the appropriate files, such as web.config for IIS. This is a typical use case and we have a simple script we can share. Another example of a scripted configuration change is the case where the app stores the machine name somewhere in its configuration and it needs to be changed when the app is moved.
