A growing number of organisations are using the public Cloud, but UXC Cloud Solutions positions the private Cloud as the better option in some use cases.
CEO, Sean Mathieson, said specialty requirements around hardware or configuration is one deciding factor.
"In some cases, enterprises and government agencies cannot get the hardware or infrastructure that a particular application needs from a public Cloud provider," he said.
If, for example, a workload needs a virtual machine with 24GB of RAM and just two CPUs, Mathieson said the public Cloud may not be a cost effective setup if the provider offers the biggest instance type it has available.
Then there are governance or regulatory requirements to take into account.
"In some cases, security or governance issues force enterprises and government agencies into using a private Cloud," Mathieson said.

The full cost
If enterprise or government users are in an area distant from a public Cloud provider, Mathieson said network latency can be an obstacle.
"Latency could slow down access to an application and make a private Cloud a better option," he said.
"Similarly, a Cloud application for your internal users may run faster using an on-premises private Cloud."
Adopting the Cloud is an investment, a substantial one in some cases, so Mathieson said it is important to keep the total cost of ownership (TCO) over the projected life of the Cloud project.
"For workloads that have a steady state load 24x7, it is likely that a private Cloud is more cost-effective than on-demand public Cloud infrastructure," he said.
Whether it is a public and private Cloud service, Mathieson said it creates an opportunity for a "new generation" of resellers and partners.
"The ongoing evolution provides an environment for partners to develop new operating models based on end-to-end services enablement, including subscription licensing, services integration and services management," he said.
