What is a hybrid cloud?
A hybrid cloud is a computing environment which combines a public cloud and a private cloud by allowing data and applications to be shared between them. When computing and processing demand fluctuates, hybrid cloud computing gives businesses the ability to seamlessly scale their on-premises infrastructure up to the public cloud to handle any overflow—without giving third-party datacentres access to the entirety of their data. Organisations gain the flexibility and computing power of the public cloud for basic and non-sensitive computing tasks, while keeping business-critical applications and data on-premises, safely behind a company firewall.
Using a hybrid cloud not only allows companies to scale computing resources, it also eliminates the need to make massive capital expenditures to handle short-term spikes in demand as well as when the business needs to free up local resources for more sensitive data or applications. Companies will pay only for resources they temporarily use instead of having to purchase, programme and maintain additional resources and equipment which could remain idle over long periods of time. Hybrid cloud computing is a “best of all possible worlds” platform, delivering all the benefits of cloud computing—flexibility, scalability and cost efficiencies—with the lowest possible risk of data exposure.
