A "multi-cloud infrastructure" involves utilizing multiple cloud computing services from different providers to meet an organization's IT needs. This strategy allows businesses to leverage the unique strengths and capabilities of each cloud environment, enhancing flexibility and avoiding vendor lock-in. A well-implemented multi-cloud infrastructure enables organizations to optimize resources, enhance disaster recovery strategies, and improve overall performance. It can also help mitigate risks associated with outages or data breaches by diversifying resource allocation. In essence, a multi-cloud infrastructure aims to provide the best combination of services tailored to specific business objectives and needs.
