Cloud computing has completely revolutionised how technology is deployed and used. For a rapidly growing number of public and private organisations, especially those in high growth mode, cloud computing offers a cost-effective highly scalable solution for deploying and using almost any application.
Cloud computing services are typically offered in three different models: private, public, or hybrid.
Private cloud services are delivered from a business’s premise data centre or co-location facility directly to internal users.
This model offers the versatility and convenience of the cloud, while preserving the management, control, and security common to local data centres.
Public cloud services are typically delivered by a third-party cloud service provider over the internet.
Public cloud services are sold on demand, typically by the minute or hour, though long-term commitments are available for many services.
Customers only pay for the CPU cycles, storage, or bandwidth they consume.
A hybrid cloud is a combination of public cloud services and an on-premises private cloud, with orchestration and automation between the two.
A hybrid cloud creates a unified, automated, scalable environment that takes advantage of all that a public cloud infrastructure can provide, while still maintaining control over mission-critical data like a private cloud.
