A multi-cloud reference architecture provides a standardized framework for designing and implementing these solutions, ensuring consistency and scalability across diverse cloud environments. Cloud computing tools are crucial in building robust multi-cloud solutions by strategically distributing applications and services across multiple platforms to optimize performance, cost and resilience.

Multi-cloud vs hybrid cloud

Definition and differences

While multi-cloud and hybrid cloud are often used interchangeably, they refer to different architectures. Multi-cloud involves using services from multiple cloud providers (e.g., AWS, Azure, GCP), while hybrid cloud combines private cloud infrastructure with one or more public cloud services. Hybrid multi-cloud architecture combines the strengths of both multi-cloud and hybrid cloud, enabling organizations to integrate on-premises infrastructure with multiple public cloud providers seamlessly.

The primary difference lies in integration: hybrid cloud focuses on seamless integration between private and public clouds, while multi-cloud leverages multiple public clouds without necessarily integrating them.
