The SLA for virtual machines guarantees 'uptime'. The amount of uptime guaranteed depends on factors such as whether the VMs are in an availability set or availability zone if there is more than one VM, the distribution of the VMs if there is more than one or the disk type if it is a single VM.
The SLA for Virtual Machines states:
-> For all Virtual Machines that have two or more instances deployed across two or more Availability Zones in the same Azure region, we guarantee you will have
Virtual Machine Connectivity to at least one instance at least 99.99% of the time.
-> For all Virtual Machines that have two or more instances deployed in the same Availability Set or in the same Dedicated Host Group, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.95% of the time.
-> For any Single Instance Virtual Machine using Premium SSD or Ultra Disk for all Operating System Disks and Data Disks, we guarantee you will have Virtual
Machine Connectivity of at least 99.9%.

The SLA specifies the level of service that customers can expect and the compensation they will receive if the service falls below the agreed level of service.
Regarding the SLA for virtual machines in Azure, the guaranteed aspect is uptime. This means that Microsoft guarantees that virtual machines will be available and running at least 99.9% of the time. This uptime guarantee applies to both virtual machines deployed through the Azure Portal and virtual machines deployed using Azure Resource Manager templates.
However, it's important to note that the SLA only applies to virtual machines that have two or more instances deployed in the same Availability Set. An Availability Set is a logical grouping of virtual machines in a data center that ensures that the virtual machines are deployed across multiple fault domains and update domains, providing higher availability and resiliency.
In addition to the guaranteed uptime, the SLA also includes a service credit that customers can claim if the virtual machine falls below the guaranteed uptime. The service credit is calculated as a percentage of the customer's monthly bill and is based on the duration of the outage.
To summarize, the Azure SLA for virtual machines guarantees uptime of at least 99.9% for virtual machines deployed in an Availability Set, and provides a service credit if the uptime falls below the guaranteed level. The SLA does not guarantee feature availability, bandwidth, or performance for virtual machines.
