Technically, every hybrid cloud is a type of multicloud. However, the word “multicloud” is used to refer to the use of multiple public cloud environments to provide services. This contrasts with hybrid clouds, which always involve some combination of public and private clouds. Businesses often opt for multicloud use to avoid being tied to a single cloud service provider. In particular, those industries that deal with sensitive data, including the health care and finance industries, are likely to opt for a multicloud solution rather than relying on any single public cloud, for security reasons.
Because multiclouds use multiple infrastructures and environments, they can support multiple cloud storage options and can deliver Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS). By spreading out applications across multiple clouds, companies can also develop the kind of redundancy that allows resilience in online usage.
The choice of a multicloud rather than a private cloud will affect the applications, security choices, and other tools you opt for. When using a multicloud, your business’s IT team is likely to choose tools that operate equally well across the major public clouds. A multicloud solution lets enterprises choose the right cloud solution for various departments, since a software engineering department, for instance, is likely to have significantly different storage and application needs than the sales department.
Where hybrid clouds allow the different components to work together seamlessly, multiclouds silo data in separate clouds. This siloing allows a far greater emphasis on data security, since the greatest risk to data privacy and security occurs during the transfer of data between clouds. Business that have no specific need to share apps or data across clouds often find the multicloud solution to be the right one for their needs. In fact, Gartner has predicted a 70% adoption of a multicloud strategy by U.S. businesses.
