Red Hat recently conducted a global customer survey about this and results indicate that customers prefer hybrid cloud over public cloud. So there may be some bias in that many of these clients have already opted for that path, but nonetheless it does highlight why they did so:
There are many reasons why customers prefer hybrid over public cloud or pure private cloud. Red Hat says it boils down to three factors: data security, cost benefits, and data integration.
“Everyone accepts that cloud is secure; however, operators are starting to question how well they can control their data in cloud. Also, some of them don’t trust the cloud vendors, especially with some of the new analytics services,” said Hirschfeld.
Hybrid cloud enables customers to balance all three factors highlighted in the Red Hat survey. They can move pieces of their infrastructure between public and private cloud depending on the need. It lets them reap the benefits of public cloud without having to compromise their data.
The bottom line is a company should have a cloud strategy which is based on an actual business need. Don’t rush into cloud for the sake of it being cloud. Cloud can burn you too in terms of cost, control, integration, etc if you are not careful. It could end up being quite costly if you cannot exit out again or cannot easily migrate to a different cloud. Which is why many opts for a hybrid approach.

As the cloud native space is maturing, customers have started to discern the pros and cons of public cloud. They can see not just the facade of convenience and promised cost savings, but also the bills piling up and having to hand over critical business data to public cloud companies.
