Is using MS SQL Identity good practice?

Question

Is using MS SQL Identity good practice in enterprise applications? Isn\'t it make difficulties in creating business logic, and migrating database from one to another?

Answer 1

Yes, they work very well and are reliable, and perform the best. One big benefit of using identity fields vs non, is they handle all of the complex concurrency issues of multiple callers attempting to reserve new id's. This may seem like something trivial to code but it's not.
