Administration of an Azure VM isn't limited to managing the operating system, or software that runs on the VM. It helps to know which services Azure provides that ensure service availability and support automation. These services help you to plan your organization's business continuity and disaste...
Azure VM SLA Below are the SLA's for the Azure Virtual Machines. 99.9%, Single VM 99.95%, 2 or more VMs in an Availability Set 99.99%, 2 or more VMs into Availability Zone Note This Service Level Agreement for Microsoft Online Services (this “SLA”) is a part of your Micr...
VMs part of failover cluster can be placed in different availability zones, helping you achieve a zone-redundant SQL Server FCI that provides a VM availability SLA of 99.99%. Disk latency for ZRS is higher due to the cross-zonal copy of data. Premium SSD Locally Redundant Storage (LRS):...

在多個 VM 上執行的應用程式使用具有彈性協調流程模式的區域備援虛擬機擴展集,或跨三個可用性區域部署 VM 和磁碟,將 VM 和磁碟分散到多個可用性區域。跨多個區域部署時,多個 VM 具有最高的運行時間 SLA。 透過具有彈性協調流程模式或可用性設定組的區域虛擬機器擴展集,跨多個容錯網域部署 VM 和磁碟。跨容錯網域...
Combining availability set and proximity placement group provides the lowest latency for shared disks as data is replicated locally within one data center and provides VM availability SLA of 99.95%. Ultra Disk Locally Redundant Storage (LRS): Availability zone but the VMs must be placed...

AndAvailability SetsandAvailability Zones, which help spread virtual machine groups like domain controllers across the datacenter or even multiple zones within the...
ZRS disks will provide improved availability through storage-level replication. For example, if a zone goes down due to natural disasters or hardware failures, the ZRS disk will continue to be operational. If your VM in the affected zone becomes unavailable, you could use a virtual machine ...
SLA. These mechanisms protect the high availability of the VMs but not the high availability of SQL Server running inside the VMs. It is possible for the SQL Server instance to fail while the VM is online and healthy. Moreover, even the high availability mechanisms provided by Azure allow ...
Avoid Configuring Single VMs in an Availability Set When a virtual machine is deployed in Azure it can be configured to be either part of anavailability setor to have the availability set configured to‘None’. The‘None’option can be slightly misleading because everyone would l...
