Using services from multiple cloud providers to avoid vendor lock-in and optimize performance. Like shopping at different stores to get the best deals and products.
A company uses AWS for compute, Google Cloud for analytics, and Azure for Office 365 integration.
Multi-cloud is an architecture strategy (not a single service) where you intentionally use two or more cloud providers. It’s commonly enabled by cross-cloud networking, identity federation, portable deployment (containers/Kubernetes), CI/CD, and centralized observability/governance rather than a provider-specific product.
