Customize VM assessment properties

This article describes VM assessment properties that you can use to customize the assessment to fit your requirements. Also, see the general assessment properties that are applicable for all workloads in cross-workload assessment.

Assessment properties

This section describes the components that are part of an assessment.

Setting Category	Setting	Details
Target settings	Target VM series	The Azure VM series that you want to consider for rightsizing. B-Series VM families are not selected by default in case the Production environment type is selected in general settings. In case you want to assess the VMs in the assessment scope for burstable VM targets add them explicitly Learn more. Cobalt 100 VMs will only be recommended in case the on-premises VMs are on ARM64 CPU architecture Learn more. For example, if you don't have a production environment that needs A-series VMs in Azure, you can exclude A-series from the list of series. The availability of VM series depends on the target location selected. Learn more.
Target settings	Target storage disk	Specifies the type of target storage disk as Premium-managed, Standard HDD-managed, Standard SSD-managed, or Ultra Disk. If you want a single-instance VM service level agreement (SLA) of 99.9%, consider using Premium-managed disks. This ensures that all disks are recommended as Premium-managed disks. If you're looking to run data-intensive workloads that need high throughput, high IOPS, and consistent low latency disk storage, consider using Ultra Disks. Azure Migrate supports only Managed disks for migration assessment.
Right-Sizing	Sizing criteria	This attribute is used for right-sizing the target recommendations. Use as-is on-premises sizing if you don't want to right size the targets and identify the targets according to your configuration for on-premises workloads. Use performance-based sizing to calculate compute recommendation based on CPU and memory utilization data and storage recommendation based on the input/output operations per second (IOPS) and throughput of the on-premises disks.
	VM uptime	The duration in days per month and hours per day for Azure VMs that won't run continuously. Cost estimates are based on that duration. The default values are 31 days per month and 24 hours per day.
	Azure Hybrid Benefit	Specifies whether you have software assurance and are eligible for Azure Hybrid Benefit to use your existing OS licenses. For Azure VM assessments, you can bring in both Windows and Linux licenses. If the setting is enabled, Azure prices for selected operating systems aren't considered for VM costing.

Note

• Azure Migrate supports only Managed disks for migration assessment.
• In Azure Government, it is recommended to review the [supported target] assessment locations. VM size recommendations in assessments will use the VM series specifically designed for Government Cloud regions.  Learn more.
