Microsoft has announced SSD bursting capabilities. This means that Premium SSD disks can achieve higher peak loads than the maximum IOPS with a new maximum of 3500 IOPS and a bandwidth up to 170 MiB/s. Together with this announcement Microsoft also announced new disk sizes (4, 8 & 16 GiB)
With the new bursting disks you can achieve up to 30 times the provisioned bandwidth, which will give better performance for spiky workloads. Disk bursting is based on a credit system. You will receive bursting credits when traffic is below the provisioned limit. Let me try to explain it using a simple chart.
With an increased security and privacy in mind Microsoft has been working on private links to Azure resources. Azure Private Link is a secure way to consume Azure Services like Azure SQL and Azure Storage using a private connection in your own VNet. This will replace the need for IaaS hosted virtual machines with SQL Server or the file server role installed.
Azure Private Link brings Azure services inside the customer’s private VNet. The service resources can be accessed using the private IP address just like any other resource in the VNet. It is basically an NIC inside one of your VNET’s. This will allow all traffic to flow over the internal network, and will not go over the internet. There is no need to put gateways or any other network devices in place to make this happen.
