Is it a good way to have a separat host instance for each send port?

Hi there.

I’m looking for the best way to handle different send ports in one BizTalk application in case updates will come.

Background:
I want to create a biztalk application to orchestrate incoming Messages. Some send ports are subscribed on this orchetsration/message. Each send port ends on a seperate backend System. Now I think to create for each backend system for each send port a seperate host instance. So I can maintain or shut down each send port seperately if necessary.

Will this be a good approach or do I overlook something?

Please let me know what you think of it or if you will have a better idea?

Thanks,
Wolfgang
