Hi Blertin
With regards to saving on licensing cost's I would point out below reply from John in
this thread-
If you have
Software Assurance on you BizTalk Licenses, you can keep a dark BizTalk Group ready at the backup site which can be activated, turned on, in a DR scenario.
You would have to keep it in sync app and config wise with your primary site. Meaning, when you rev the apps on PROD, you also have to rev them in DR.
Also, you may find
this thread helpful-
If you are using BizTalk
log-shipping as your BizTalk Server Databases DR strategy, you should be fine.
Note that this is the only supported DR strategy for your BizTalk SQL databases.
For the application servers, there are no restrictions from Microsoft on the DR strategy. So, VMWare SRM if configured fine should work as well. Note that with DR, you have to test sufficiently, that the whole setup works fine. Do a few DR runs to make
sure that you don't have any issues. Note that you have to restore the ENTSSO master secret key from Prod Master Secret Server on the DR Master Secret Server as part of building the DR site as documented here.
There are few things to keep in mind while creating a BizTalk DR plan. Refer below links-
