Ubuntu is a popular choice for Virtual Machines running on Microsoft Azure and Hyper-V. Yesterday Microsoft and Canonical that they will provide an Azure Tailored Kernel for Ubuntu. Microsoft and Canonical were already working on a lot of projects together, like Linux Containers on Windows using Docker, or the Windows Subsystem for Linux.
Canonical, with the team at Microsoft Azure, are now delighted to announce that as of September 21, 2017, Ubuntu Cloud Images for Ubuntu 16.04 LTS on Azure have been enabled with a new Azure tailored Ubuntu kernel by default. The Azure tailored Ubuntu kernel will receive the same level of support and security maintenance as all supported Ubuntu kernels for the duration of the Ubuntu 16.04 LTS support life.
The kernel itself is provided by the linux-azure kernel package. Some of the special feature this kernel provides are:
- Infiniband and RDMAcapability for Azure HPC to deliver optimized performance of compute intensive workloads on Azure A8, A9, H-series, and NC24r.
- Full support for Accelerated Networking in Azure. Direct access to the PCI device provides gains in overall network performance offering the highest throughput and lowest latency for guests in Azure. Transparent SR-IOV eliminates configuration steps for bonding network devices.
- NAPI and Receive Segment Coalescing for 10% greater throughput on guests not using SR-IOV.
- 18% reduction in kernel size
- Hyper-V socket capability — a socket-based host/guest communication method that does not require a network.
- The very latest Hyper-V device drivers and feature support available.
I am sure these improvements will not only help Ubuntu Virtual Machines running on Azure, but also Ubuntu Virtual Machines running on Hyper-V
Canonical and Microsoft also promise to work close in the future to deliver more new feature.
As we continue to collaborate closely with various Microsoft teams on public cloud, private cloud, containers and services, you can expect further boosts in performance, simplification of operations at scale, and enablement of new innovations and technologies.
Really looking forward how this works. Also funny to see the comments on the Tweet from the @Ubuntu on twitter, which shows how many people live in the old world.
