You are trying to get an end-of-quarter report out and you’re having some trouble. It seems that while sales are recorded on a public cloud system, inventory is recorded on an on-premises system. You need to combine both data stores for the report, and you have no way of doing so. How was this allowed to happen?
The fact of the matter is that all legacy systems and data can’t migrate to the public cloud, so those on-premises systems need to integrate with the data on the public cloud systems to function. While this was a known problem in 2011 when we started on the cloud journey, in 2018 many organizations still have still not gotten around to solving it.
