What is Multicloud?
An organization takes a multicloud approach when it uses cloud services from more than one provider. That might seem obvious from the name—it's multiple clouds, after all—but the reasons for choosing a multicloud approach can be as varied as the cloud platforms themselves.
Because "cloud" has become such a broad and all-encompassing category, a multicloud environment might include, say, Microsoft 365 SaaS for productivity apps, Google Drive for storage, and Amazon AWS for compute services.
On the other hand, organizations might have a reason to turn to multiple cloud providers for the same function or purpose. And public cloud services are so cheap and easy to get started with that large organizations (or organizations that don't have tight centralized control over IT) might find themselves in a multicloud situation without ever intending to.
