Multi-cloud is a type of software or data architecture, in which the same organization uses more than one 'cloud'. This could mean multiple public cloud providers (e.g., storing data on AWS and running some workloads on Azure), or hybrid architectures that combine public and private clouds.

A multi-cloud architecture can provide greater flexibility and performance as organizations can choose the specific cloud services that best meet their needs – regardless of where these services are hosted.

Multi-cloud deployments pose new challenges for data security due to the difficulty in tracking data lineage and movement between clouds. As these patterns grow in popularity, the cybersecurity ecosystem will need to provide a new set of solutions for detecting and mitigating related data risks.
