I'm application architect at enterprise-type org. We have a few SaaS applications, but all the big dogs, including custom dev, run in-house on a dual data centre vmware environment. It's cheaper for us to spin up more VMs in-house, so there's no real cloud driver for things that just live on VMs. On the other hand, our ops team are still working on network segmentation and self-service, but I regularly get a standard VM provisioned in less than 20 mins. If we had to buy new data centres it might be different. But the real reason we're not deeper in the cloud is that our business-types insist on turn of the century, server-based software from the usual big vendors, and all the things that integrate with them need to use 20th century integration patterns, so for us migrating to the cloud (in stages at least) would have drawbacks from all options without the benefits. It's only where we have cloud-native stuff that we can sneak in under the radar for stand-alone greenfields projects, or convince the business types that they can replace the Oracles and Peoplesofts with cloud-first alternatives will things really change.
