It is false that Azure Service Health can ensure 100% availability of Azure Virtual Machines. Azure Service Health helps in monitoring but cannot guarantee absolute uptime; strategies like Availability Sets and Azure Site Recovery are required for high availability.
The statement that you can ensure your Azure Virtual Machine will have 100% availability using Azure Service Health, even in a service failure event, is false. While Azure Service Health provides tools to monitor the status and health of Azure services, it cannot guarantee 100% availability of your virtual machines. To maximize availability, you should implement redundancy and failover strategies like Availability Sets or Zones, and consider the use of Azure Site Recovery for disaster recovery planning.
Azure's strongest guarantee in terms of availability is the 99.99% uptime for virtual machines that use Premium Storage and are deployed across two or more Availability Zones within the same Azure region.
In conclusion, although Azure Service Health is essential for monitoring, it is not a tool that can ensure absolute availability. Instead, a combination of Azure's resilience features and services should be employed to achieve the highest possible uptime.
