451 Research has recently published an article and supporting graphic, “The cloud transformation journey: Great expectations lead to a brave new world.” I think they have the equation flipped.
In the wake of “massive repatriation” of workloads out of the cloud to on-premise I think we need to not only change our thinking from “cloud-first” to “cloud-last”, but also that this has to be coupled to an attitude that you can’t beat the cloud with a smaller cloud, i.e. it’s not just about going to hybrid cloud but taking stock of the entirety of an organization’s (existing) IT infrastructure. A complete cloud strategy needs to add the foundational element of #recapture of all potential unused compute cycles, whether it be on desktops, legacy servers, or even new on-premise cloud servers.
If you look at analyst reports such as “The cloud transformation journey: Great expectations lead to a brave new world” report from 451 Research (February 2018) they show repatriation as a key component of waste management and cost optimization. But only 6.4% to a non-cloud environment, 32.2% to private cloud, the majority still hosted rather than on-premise. I would contend that all organizations are missing the potential of their non-cloud environment… and the expenditure curve could be lowered even further.
