The node cost is computed by taking the most cost optimum AVS node SKU. A default CPU over-subscription of 4:1, 100% memory overcommit and compression and deduplication factor of 1.5 is assumed to get the compute cost of AVS.

+**Estimated AVS cost**:  This card includes the total cost of ownership for hosting all workloads on AVS including the AVS nodes cost (which includes storage cost), networking, and labor cost. The node cost is computed by taking the most cost optimum AVS node SKU. The infrastructure settings used are as follows:
+    
+- The number and SKU of AVS hosts used in a business case aligns to the SKUs available in the given region and optimized to use the least number of nodes required to host all VMs ready to be migrated.
+- Azure NetApp File (ANF) is used when it can be used to optimize the number of AVS hosts required. ANF Standard tier is used when the VMs have been imported using RVTools. For an Azure Migrate appliance-based business case, the tier of ANF used in the business case depends on the IOPS & throughput data for VMs.

    - **Compute and license cost**: Estimated as a sum of total server hardware acquisition cost on-premises, software cost (Windows license, SQL license, Virtualization software cost), and maintenance cost, SQL license cost is assumed to be using pay-as-you-go model via Arc-enabled SQL Server. ESU licenses for Windows Server and SQL Server are also assumed to be paid via Azure through ESUs enabled by Azure Arc.
    - **Security and Management Cost**: Security cost is estimated as sum of total protection cost for general servers and SQL workloads using MDC via Azure Arc and management cost is estimated as sum of total management cost  for general servers.
    - **Storage, Network and facilities cost** : Storage cost is Cost per GB and can be customized in the assumptions. Network and facilities cost is considered same as that of current on-premises costs.
