Multi-Cloud, also spelt as ‘multicloud’, is an emerging model of cloud computing. It refers to the use of two or more cloud computing services from more than one cloud service provider. The multi-cloud approach takes heterogeneous Infrastructure-as-a-Service (IaaS) and Software-as-a-Service (SaaS) services and deploys them in a single cloud environment to meet the business goals. There are several benefits of the multi-cloud model that include availability, customisability, security, scalability, and flexibility.
Points to Remember
- An organisation may adopt a multi-cloud approach due to several reasons, such as for minimising its dependence on one cloud vendor, more flexibility in cloud services, and complying with certain laws.
- On the surface, the multi-cloud and the hybrid cloud approach look similar. However, there is one key difference between cloud models. A hybrid cloud is a combination of a public cloud model and a private cloud. In contrast to a hybrid cloud, the multi-cloud model can pair one or more public clouds with a private cloud or simply, combine two or more public clouds.
