Azure regions are geographical locations around the world that host Azure datacenters. Each Azure region is a separate geographic area where Microsoft operates one or more datacenters to deliver Azure services.
Azure regions are strategically distributed to provide customers with options for deploying their applications and services in close proximity to their target users or to meet specific regulatory or compliance requirements. Azure regions are designed to be geographically isolated from each other to provide fault tolerance and data redundancy.
No, the solution suggested by Josh would not meet the requirement of ensuring that the virtual machines remain available during the disk migration process.
To meet the requirement of replicating the disks of the virtual machines to Azure while keeping the virtual machines available, you should consider using Azure Site Recovery (ASR).
Azure Site Recovery provides a robust and seamless solution for replicating virtual machines from on-premises Hyper-V clusters to Azure. It offers continuous replication, automated failover, and failback capabilities to ensure minimal downtime and data loss during the migration process.
Availability Zones in Azure regions are physically separate datacenters within the same region that are designed to be isolated from each other in terms of power, networking, and cooling infrastructure. These availability zones provide customers with additional options for ensuring high availability and fault tolerance for their applications and services.
Each Azure region consists of multiple availability zones, typically three or more, that are geographically dispersed within the region. These availability zones are connected through high-speed and low-latency networking to enable data replication and failover capabilities.
When deploying a resource in Azure, one of the key decisions you often need to make is choosing the region where you want your resource to be deployed. The region selection is an important decision that can have implications on various aspects of your application or service, including performance, availability, compliance, and data sovereignty.
