Which service will allow virtual machines to remain accessible during their migration to Azure?

Azure Storage account with AzCopy
Data Migration Assistant
Azure Site Recovery
Standard Azure Blob storage

The correct answer is: Azure Storage account with AzCopy

The service that allows virtual machines to remain accessible during their migration to Azure is Azure Site Recovery. This service provides a seamless experience for migrating workloads to Azure while ensuring high availability. When using Azure Site Recovery, the virtual machines continue to operate on-premises during the initial migration phase. The replication of data occurs in the background, allowing users to experience minimal downtime. This capability is particularly crucial for businesses that cannot afford interrupted access to their critical applications during the migration process. Once the replication is complete, applications can failover to Azure, at which point they will be fully accessible from the cloud. While Azure Storage accounts with AzCopy, the Data Migration Assistant, and Standard Azure Blob Storage have their own use cases for data transfer and storage, they do not provide the same level of continuous accessibility for virtual machines during migration as Azure Site Recovery does. Therefore, Azure Site Recovery is the optimal solution for ensuring that virtual machines are still reachable while the migration is taking place.
