Abstract: In an era of digital transformation and cloud adoption as key IT strategies, ensuring business continuity and resilience against failures has become critical for enterprises. Disaster Recovery as a Service (DRaaS) has emerged as an essential component in cloud solutions, providing automated failover, replication, and recovery mechanisms to mitigate system disruptions. Microsoft Azure Site Recovery (ASR) stands out as a comprehensive, scalable, and cost-effective disaster recovery solution, particularly for organizations using VMware virtual machines (VMs) on-premises. This paper analyzes ASR's architecture, configuration, and failover mechanisms, elucidating key components such as the Configuration Server, Process Server, Mobility Service, Master Target Server, and Recovery Services Vault. It examines the methodology to implement ASR for VMware VM replication, including Azure and on-premises configurations, deployment of replication components, and policy-driven data protection. The failover and failback processes are scrutinized, emphasizing ASR's capacity to ensure minimal downtime, near-instantaneous recovery, and operational continuity. Through examination of ASR's integration with VMware environments, this paper underscores its advantages in automating disaster recovery workflows, facilitating seamless workload transitions between on-premises and cloud environments, and enhancing security and compliance. The findings substantiate Azure Site Recovery's position as a leading DRaaS solution that mitigates business risks associated with infrastructure failures while optimizing cost and performance for VMware-based workloads.
