Azure Disk Storage

Azure Disk Storage is a block-level storage service designed for virtual machines within Microsoft Azure. It serves as the primary storage solution for hosting operating systems, applications, and data for cloud-based workloads. This service ensures persistent data retention for virtual machines, allowing them to store information reliably even when the underlying compute instances are stopped or restarted.

You should choose this service when running Azure virtual machines that require durable, low-latency block storage for their operating systems and applications. Be aware that there is no free tier available for this storage option. The pricing model operates on a pay-as-you-go basis, meaning costs accumulate based on the amount of storage provisioned and used, requiring careful budget monitoring to avoid unexpected charges.
