Highly durable and available with design for 99.First, there is a difference between Snapshots and Backups:.

Better reliability for Availability Sets.Now with managed disks, this is as easy as shutting down the virtual machine and just changing a value in a drop down. Ability to convert a Standard disk to Premium disk and vice versaĮarlier if you wanted to convert a standard disk to a premium disk (or vice versa) you needed to create a new storage account and copy over the disk. The images that you capture on the Vms, which are created using managed disks, will not just include the OS disk, but will also include all the data disk. You can take these snapshots onto a different storage account. You can later restore from these snapshots as required. Now with managed disks you have the capability to take snapshots on the fly. With managed disks, you are no longer limited by the storage account limits. When the infrastructure grew and there comes a time the number of disks grew to a point that this service limit will be hit and this can affect your architecture. No Storage account service limitsĮarlier with storage accounts there were Service Limits related to IOPS at the storage account level. If a VM has 1 OS disk and 2 data disks, all implemented as a managed disk, then you can even provide the access to one of the data disk and not provide access to any of the other disks. Managed Disks are individual resources in Azure. This inadvertently opened the access to the Finance VM's VHD files as well. This was the lowest level where you could provide the access. Now if you want to give access to a VHD file of a VM belonging to HR department, you will provide the access to the storage account. Let us say that there are VMs belonging to Finance as well as HR departments.

Let's assume a scenario where all the disks for the virtual machines in your environment belonged to a particular storage account. In this post, lets take a look at what all benefits you get when you create your virtual machine with a managed disk instead of a storage account based disks. The first thing to note is that these are only related to VM disks and not general blob storage. Why you should be using Azure Managed Disks now? 05, 2017Īzure Managed Disks bring lots of advantages and benefits to the table when compared to Azure Storage Account based VM disks.
