Multi-cloud means using cloud services from more than one cloud provider. A company might run workloads on one provider, store data on another, and use a third provider for specialized services.
Why companies use multi-cloud
Multi-cloud can reduce dependence on one provider, improve regional coverage, match workloads to stronger services, or meet business and compliance needs. It can also increase complexity.
Multi-cloud versus hybrid cloud
Hybrid cloud combines different environments such as public cloud, private cloud, and on-premises systems. Multi-cloud specifically means more than one cloud provider.
A good multi-cloud strategy needs strong governance, networking, security, and cost management.
