General assessment properties

This article explains the assessment properties on the General tab that you can use when creating an assessment. These general properties apply to all workloads in an application or for cross-workload assessments. They also apply to individual workload assessments.

Setting Category  Default Setting Details
Target settings Target location The Azure region to which you want to migrate. Azure target configuration and cost recommendations are based on the location that you specify.
Target settings Default Environment  The environment for the target deployments to apply pricing applicable to Production or Dev/Test.
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. Use the storage recommendation based on the input/output operations per second (IOPS) and throughput of the on-premises disks.
Right-Sizing  Performance history  Used with performance-based sizing. Performance history specifies the duration used when performance data is evaluated.
Right-Sizing Percentile utilization  Used with performance-based sizing. Percentile utilization specifies the percentile value of the performance sample used for rightsizing. Learn more about sampling mechanism.
Right-Sizing Comfort factor  This is the buffer applied during assessment. It's a multiplying factor used with performance metrics of CPU, RAM, disk, and network data for VMs. It accounts for issues like seasonal usage, short performance history, and likely increases in future usage. The comfort factor is applied irrespective of type of assessment (As-is on premises or performance based). For performance-based assessment, it's multiplied with utilization value of the resources, whereas for As-is on premises assessment it's multiplied by allocated resources.
The default values change. 
For example, a 10-core VM with 20% utilization normally results in a two-core VM. With a comfort factor of 2.0, the result is a four-core VM instead. 
Pricing settings  Default savings option   Specify the savings option that you want the assessment to consider to help optimize your Azure compute cost.
Azure reservations (One year or three years reserved) are a good option for the most consistently running resources.
Azure Savings Plan (One year or three years savings plan) provide additional flexibility and automated cost optimization.
When you select None, the Azure compute cost is based on the Standard Pay-in-Advance Offer rate considering 744 hours as VM uptime, unless specified otherwise in VM uptime attribute.
Offer/Licensing program The Azure offer in which you're enrolled. The assessment estimates the cost for that offer. Select one of the Standard Pay-in-Advance Offer, or Enterprise Agreement support.
You need to select Standard Pay-in-Advance Offer in offer/licensing program to be able to use Reserved Instances or Azure Savings Plan. When you select any savings option other than None, the Discount (%) and VM uptime properties aren't applicable. The monthly cost estimates are calculated by multiplying 744 hours in the VM uptime field with the hourly price of the recommended SKU.
Currency The billing currency for your account.
Discount (%) Any subscription-specific discounts you receive on top of the Azure offer. The default setting is 0%.
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 if 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.
Security Security Specifies if you want to assess readiness and cost for security tooling on Azure. If the setting has the default value Yes, with Microsoft Defender for Cloud, it assesses security readiness and costs for your Azure VM with Microsoft Defender for Cloud.
VM Security Type Specifies is you want to verify readiness for Trusted Launch Virtual Machines (TVMs), Standard Virtual Machines, or both. By default, readiness is verified for both. We recommend to migrate eligible VMs to Trusted Launch, as TVMs provide enhanced security features, such as secure boot and virtual TPM at no extra cost.
