 ## Utilize Lifecycle Management
 Azure Advisor will utilize intelligence regarding your Azure blob storage object count, total size, and transactions to detect if one or more of your storage accounts would be best suited to enable lifecycle management to tier data. It will prompt you to create Lifecycle Management rules to automatically tier your data to Cool or Archive to optimize your storage costs while retaining your data in Azure blob storage for application compatibility.
 
+## Create an Ephemeral OS Disk recommendation
+With [Ephemeral OS Disk](https://docs.microsoft.com/azure/virtual-machines/windows/ephemeral-os-disks), Customers get these benefits: Save on storage cost for OS disk. Get lower read/write latency to OS disk. Faster VM Reimage operation by resetting OS (and Temporary disk) to its original state. It is more preferrable to use Ephemeral OS Disk for short-lived IaaS VMs or VMs with stateless workloads. Advisor has recommendation for resources which can take benefits with Ephemeral OS Disk.

 Virtual machines that are in an availability set with disks that share either storage accounts or storage scale units are not resilient to single storage scale unit failures during outages. Advisor will identify these availability sets and recommend migrating to Azure Managed Disks. This will ensure that the disks of the different virtual machines in the availability set are sufficiently isolated to avoid a single point of failure.

 ## Ensure application gateway fault tolerance
 
 This recommendation ensures the business continuity of mission-critical applications that are powered by application gateways. Advisor identifies application gateway instances that are not configured for fault tolerance, and it suggests remediation actions that you can take. Advisor identifies medium or large single-instance application gateways, and it recommends adding at least one more instance. It also identifies single- or multi-instance small application gateways and recommends migrating to medium or large SKUs. Advisor recommends these actions to ensure that your application gateway instances are configured to satisfy the current SLA requirements for these resources.

+## Increase batch size when loading to maximize load throughput, data compression, and query performance
+
+Advisor can detect that you can increase load performance and throughput by increasing the batch size when loading into your database. You could consider using the COPY statement. If you are unable to use the COPY statement, consider increasing the batch size when using loading utilities such as the SQLBulkCopy API or BCP - a good rule of thumb is a batch size between 100K to 1M rows. This will in increasing load throughput, data compression, and query performance.
