What is multi-cloud?

Answer

Multi-cloud is the practice of using services from more than one cloud provider, such as AWS, Azure, and Google Cloud, within a single organization or architecture. Reasons include avoiding vendor lock-in, meeting regulatory or data-residency needs, using best-of-breed services, and improving resilience. Multi-cloud differs from hybrid cloud, which combines public cloud with on-premises infrastructure. The main challenges are added operational complexity, inconsistent tooling and APIs, and the need for skills across multiple platforms.
