Multicloud

Multicloud (also written as multi-cloud or multi cloud) is a term with varying interpretations, generally referring to a system using multiple cloud computing providers. According to <a href="/facts/International_Organization_for_Standardization/IacYR7Yg">ISO</a>/IEC 22123-1: "multi-cloud is a cloud deployment model in which a customer uses public cloud services provided by two or more cloud service providers". Multi-cloud can involve various deployment models, including public, private, and hybrid clouds, and multiple service models, such as <a href="/facts/Infrastructure_as_a_service/2d9IdAxE">Infrastructure as a Service</a> (IaaS), <a href="/facts/Platform_as_a_service/EDX8mcw4">Platform as a Service</a> (PaaS), and <a href="/facts/Software_as_a_service/LPyPQ5b7">Software as a Service</a> (SaaS). Multicloud incorporates workload, data, traffic and workflow <a href="/facts/Software_portability/tWKVGCBb">portability</a> options, exhibiting differing implementation complexities.
When effectively implemented, multicloud solutions can enhance architectural resilience, reduce dependence on a single vendor, and improve flexibility by leveraging services from different providers. However, multicloud strategies also present challenges, including increased operational complexity, security risks, higher costs, and integration difficulties.
According to the 2024 State of the Cloud Report by <a href="/facts/Flexera/BWGhJPtz">Flexera</a>, multi-cloud adoption has continued to rise in 2024. Enterprises increasingly silo applications into specific clouds and select best-fit services. Key use cases include data analysis in separate clouds and cross-cloud disaster recovery.
