Multi-cloud computing is the use of more than one cloud environment to satisfy business requirements. These clouds may be all of the same type or a mix of types: a business might have multiple private clouds, multiple public clouds and multiple managed clouds, including managed services or service providers.
Multi-cloud computing can be used by enterprises, website providers, developers and other businesses to minimize the risks of data loss and downtime and to increase compute power or quality of service (QoS). The multi-cloud strategy can also help companies avoid getting locked into the rates of a single vendor and missing out on lower-cost options. Multi-cloud computing can also be used to support groups with different needs and purposes or to provide for a higher quality experience for premium users.
Being able to rely on hardware in multiple locations and perhaps from multiple providers drastically decreases the chances of issues preventing service or impacting QoS. Additional redundant cloud facilities can further improve the odds. The shift to a multi-cloud model changes the question of how to choose between private and public clouds to how to choose the right cloud at the right costs with the right characteristics. The use of multiple clouds can help an organization adapt to changing IT environments and reduce the need to replace hardware and appliances.
