One of the more common questions I’ve had over the years is: “but, surely, everyone is just in the public cloud, right?” I remember having a non-productive debate with a room full of Forrester analysts back in about 2012 where they were going on and on about on-premise IT being dead. There was much talk about electricity outlets. To be fair, the analysts were somewhat split, but the public cloud folks were adamant. You can see this same sentiment from analysts (including, before around 2011, myself!) in things like how long it’s taken to write about private PaaS, e.g., the PaaS magic quadrant has only covered public PaaS since inception).
Along these lines, the Uptime Institute has some survey numbers out. Here’s some highlights:
Some 65% of enterprise workloads reside in enterprise owned and operated data centers—a number that has remained stable since 2014, the report found. Meanwhile, 22% of such workloads are deployed in colocation or multi-tenant data center providers, and 13% are deployed in the cloud, the survey found….
On-prem solutions remain dominant in the enterprise due to massive growth in business critical applications and data for digital transformation, Uptime Institute said
Public cloud workload penetration:
That survey also found that nearly half of enterprises were still dedicating at least 70% of their yearly budget to traditional, on-premise applications, potentially pointing to growing demand for a hybrid infrastructure….
Nearly 75% of companies’ data center budgets increased or stayed consistent in 2017, compared to 2016, the survey found.
Metrics, KPIs, and what organizations are focusing on (uptime):
More than 90% of data center and IT professionals surveyed said they believe their corporate management is more concerned about outages now than they were a year ago. And while 90% of organizations conduct root cause analysis of an IT outage, only 60% said that they measure the cost of downtime as a business metric, the report found.
Demographics: “responses from more than 1,000 data center and IT professionals worldwide.”
Pretty much all Pivotal Cloud Foundry customers run “private cloud.” Many of them want to move to public cloud in a “multi-cloud” (I can’t make myself say “hybrid cloud”) fashion or mostly public cloud over the next 5 to ten years. That’s why we support all the popular public clouds. Most of them are doing plenty of things in public cloud now – though, not anywhere near “a whole lotta” – and there are of course, outliers.
This does bring up a nuanced but important point: I didn’t check out the types of workloads in the survey. I’d suspect that much of the on-premises workloads are packaged software. There’s no doubt plenty of custom written application run on-premises – even the majority of them per my experience with the Pivotal customer base. However, I’d still suspect that more custom written applications were running in the public cloud than other workloads. Just think of all the mobile apps and marketing apps out there.
Also, see some qualitative statements from CIO types.
So, the idea that it’s all public cloud in enterprise IT, thus far, is sort of like, you know: ¯_(ツ)_/¯
