Azure Elastic SAN — Simply Explained

Azure Elastic SAN addresses a storage problem that often appears only after an Azure environment begins to grow. One virtual machine with one Managed Disk is simple. But as more VMs, databases, and applications appear, each workload can end up with separate disks, separate performance limits, and separate capacity decisions. The result can be inefficient: one workload may be paying for storage performance it rarely uses while another workload needs additional capacity that it cannot borrow. Azure Elastic SAN approaches this differently by providing high-performance block storage through a shared pool. ㅤ WHY SEPARATE DISKS CAN BECOME A PROBLEM Azure Managed Disks work extremely well for many individual virtual machines. The challenge appears when environments contain many workloads with different performance patterns. A SQL database might experience its highest load at month-end. A report
