Microsoft has finally enabled Accelerated Networking to all regions and the feature is generally available.
What it does is to provide up to 30Gbps in networking throughput for Windows and latest distributions of Linux machines.

AN provides consistent ultra-low network latency via Azure’s in-house programmable hardware and technologies such as SR-IOV. By moving much of Azure’s software-defined networking stack off the CPUs and into FPGA-based SmartNICs, compute cycles are reclaimed by end user applications, putting less load on the VM, decreasing jitter and inconsistency in latency.
Which Linux and Windows servers can get this feature?
Many of latest Linux machines in Azure marketplace such as CentOS 7.4, Redhat 7.4, Ubuntu 16.04 and so on. Microsoft Windows Server 2016 and Windows Server 2012 R2 also support it.
Which VM series do you need is D/DSv2, D/DSv3, E/ESv3, F/FS, FSv2, and Ms/Mms.
