@OP Oh, yeah! Ten years ago, all managers at FMC were throwing the word "cloud", like they do now with "AI", as the "magic buzzword". We had apps in Azure, AWS, GCP and PCF. Every couple of years is a "new" migration to another cloud provider. Whoever is the cheapest, or give us a "discount".
But, yes, we still have those datacenters, and some of the cloud apps were migrated from the cloud back to those datacenters to save money.
Now, any datacenter can fail. Any cloud provider can fail. Even with all the protections and redundancies. And the consequences are vast, due to the huge number of apps concentrated in there. That's why IT wanted to keep the local IT rooms inside every plant, so the outages are local, and not company wide.
However, the mighty dollar strikes again at Ford, and the company has been moving some apps out of the plants, centralizing them without regards to the old adage about "putting all your eggs in one basket". Even worse, the quality of the infrastructure at Ford is going down due to the Ford's mantra of "penny wise, pound foolish". Every project now is about "savings" by replacing the current with an inferior quality product.
But the "savings" don't stop at hardware and software. @dk+1k825ed6j is right. Ford is negotiating the outsourcing of many IT support teams, getting rid of the FTEs and contractors. There is no need to have a high IQ to know the pattern will repeat itself. Ford will pick the cheapest provider, no matter the quality.
Therefore, the cloud providers are looking better and better everyday, at least for Ford, because the local datacenters are going to be in trouble by the end of next year, and worse on the following year.
