Multi-cloud strategy is the use of two or more cloud services to minimize the risk of widespread data loss or downtime due to a localized component failure in a cloud computing environment. Such a failure can occur in hardware, software, or infrastructure. A multi-cloud strategy can also improve overall enterprise performance by avoiding "vendor lock-in" and using different infrastructures to meet the needs of diverse partners and customers.

A multi-cloud approach can offer not only the hardware, software and infrastructure redundancy necessary to optimize fault tolerance, but it can also steer traffic from different customer bases or partners through the fastest possible parts of the network. Some clouds are better suited than others for a particular task. For example, a certain cloud might handle large numbers of requests per unit time requiring small data transfers on the average, but a different cloud might perform better for smaller numbers of requests per unit time involving large data transfers on the average. Some organizations use a public cloud to make resources available to consumers over the Internet and a private cloud to provide hosted services to a limited number of people behind a firewall. A third type of cloud, called a hybrid cloud, may also be used to manage miscellaneous internal and external services.
