From the public cloud to the onsite data center

From the public cloud to the onsite data center

There was a time when the term cloud meant public cloud, and many analysts believed that this technology would eliminate the need for companies to manage their own servers or locate the infrastructure in the data center of their choice. However, over the course of the last few years, the word hybrid has emerged, not only as an aspiration, but as the preferred model for most companies.

Although the public cloud offers great scalability and flexibility, the fact is that, in this model, the service provider makes many decisions on behalf of the customer. That\'s why, for companies that need to know how and where their data is located, local hosting remains a desirable option. Hybrid cloud gives enterprises the flexibility to choose where to place each workload based on the requirements of that individual workload.

This report looks at the typical cloud business experience through a survey of 1001 enterprise IT decision makers, finding that on-premises deployments need to be more flexible and pay-as-you-go than they have been so far.


The need for a public cloud experience in the on-premises data center

Public cloud experiences are overwhelmingly positive. Of the 1001 respondents, an impressive 97% said their experience was good or better than expected; 64% said the public cloud had exceeded their expectations. This data is quite significant when you consider that, just a few years ago, the public cloud was talked about as a new and probably immature technology.

Apparently, respondents\' hopes were high before they even started using the cloud. For every potential improvement, the majority of respondents expected the public cloud to bring more benefits, from 85% who expected improvements in resource provisioning to 65% who expected certain advantages in reducing start-up costs.

Generally speaking, reality met expectations. When asked if every potential improvement had occurred, only a small minority said they were disappointed. Public cloud provisioning and scalability were considered particularly satisfactory, with only disappointment rates of 3% and 5%, respectively. Start-up costs, utilization and cost reduction were less satisfactory but, despite this, they did not meet expectations by a derisory 8-10%.


Private experience remains an object of desire

However, despite the very positive experiences with the public cloud, there is nothing to suggest that the private cloud or on-premises deployments will disappear in the near future: two-thirds of the workloads handled by decision makers are hosted on-premises.

The 2019 451 Research study, Voice of the Enterprise: Cloud, Hosting & Managed Services, Workloads and Key Projects, found that, in all likelihood, the number of companies that would choose the private cloud as the preferred location for core business functions was set to grow from 19% to 27% over the next two years. HPe\'s Market Monitor service predicts a 15% TCAC for global public cloud revenue over the period 2018-2023, with short-distance private cloud enabling technologies at 12%.

No matter how superior the public cloud experience is, some companies simply want to know where their data is located, how it is managed, and maintain accountability for all elements of their protection. This explains why data security and privacy are high on the list of decision makers\' concerns: 68% view security and compliance as a barrier to public cloud adoption, and 60% opt for data loss. In fact, all the potential advantages/challenges we asked about were considered problems for adoption.

In a similar Voice of the Enterprise study by 451 Research, respondents viewed specific security requirements, compliance, and data protection as obstacles preventing certain workloads from being hosted in the public cloud. The control aspect was also among the top priorities, with 23% of enterprises avoiding the public cloud due to issues such as performance and availability. Cost is also at the top, perhaps due to the problem of scale: the bandwidth, storage, and other variable costs of the public cloud can soar as the severity of the data causes an increase in data in the cloud.

Considering that the public cloud is considered a positive experience and the private cloud is considered secure and compliant, it is logical that the vast majority of today\'s enterprises are taking the hybrid approach of using on-premises and public cloud deployments, with the option to choose the location based on the specific requirements of each workload. The Voice of the Enterprise study by 451 Research concludes that 57% of companies are adopting a hybrid model.
