Private cloud – additional information
Cloud computing is a model for providing networked access to a shared pool of technology resources (e.g., networks, servers, storage, applications, and services). While public cloud services are open to the general public or multiple clients, private cloud services are for the exclusive use of a single client. Private cloud can be deployed on or off premises and it can be owned, managed, and operated either by the organization, a third party, or a mixture of the two. Public cloud services, in contrast, are owned, managed, and operated by the provider. Perhaps due to the greater level of control expected from and afforded by private cloud over public cloud services, the market for dedicated hosted private cloud services is set to outgrow the market for on-demand hosted private cloud services, at least in the Asia-Pacific region.
In 2016, the extent of enterprise spending on true private cloud services - defined by a service relationship with a single provider and an ability to accommodate hybrid cloud use cases - was expected to reach 15 billion U.S. dollars worldwide, the majority of that being spent on infrastructure hardware and software. Given the increased likelihood of private cloud systems being maintained by the client organization, it is perhaps unsurprising that, as of 2015, almost twice as much was spent on private and hybrid cloud systems management software compared with public cloud systems management software.
As shown in the statistic above, the share of companies operating without a private cloud system in place appears to be relatively low. Other statistics show that enterprises appear to be becoming increasingly reliant on private cloud services to run virtual machines, with 31 percent of enterprises deploying 1000 virtual machines or more via private cloud and more than 50 percent running 100 or more. In terms of vendors, Hewlett Packard (now Hewlett Packard Enterprise) represents, by revenue, the leading vendor in the true private cloud market.
