Abstract

In today’s digital landscape, businesses face increasing pressure to maintain service continuity and data availability, especially in the face of potential service disruptions or disasters. Traditional single-cloud deployments can be vulnerable to outages, data loss, and geographical limitations. As a result, multi-cloud strategies have emerged as a solution for achieving higher resilience, disaster recovery (DR), and business continuity. By leveraging multiple cloud service providers (CSPs), organizations can architect redundancy, improve service availability, and ensure faster recovery in the event of a failure. This paper explores the importance of multi-cloud strategies for resilience and disaster recovery, focusing on key components like data replication, geographic distribution, failover mechanisms, and backup strategies. We discuss architectural patterns, best practices, and challenges of implementing multi-cloud disaster recovery solutions. Additionally, we present case studies that highlight how multi-cloud strategies enhance business resilience and improve operational continuity during disruptions.
