1 DPDK on Microsoft Azre Daniel Firestone Madhan Sivakmar DPDK Smmit - San Jose 2017 #DPDKSmmit

2 Agenda Microsoft Azre The need for DPDK in the Clod NFV Accelerated Networking in Azre Enhancements to DPDK for Clod sage Host Serviceability and VM Migration spport Pblic Preview of DPDK on Azre #DPDKSmmit 2

4 The Need for DPDK in the Clod As cstomers migrate on-prem networks and apps to the clod, NFV has become wildly poplar Poplar appliances in Azre Marketplace: Load Balancing, L7 filtering, web application firewalls, application gateways, DDoS protection, SD-WAN, and more DPDK can improve performance, throghpt, latency, and reliability for this important class of workloads Goal: How can we make DPDK appliances work well in the pblic clod? 4

connection Consistent low latency network performance Provides SR-IOV to the VM Up to 10x latency improvement as low as sb-10s

5 Azre Accelerated Networking: Fastest Clod Network! Highest bandwidth VMs of any clod Up to 30Gbps for fll-sized reglar compte VMs Standard Linx VM with CUBIC gets 30+Gbps on a single connection Consistent low latency network performance Provides SR-IOV to the VM Up to 10x latency improvement as low as sb-10s within tenants Increased packets per second (PPS) Redced jitter means more consistency in workloads Enables workloads reqiring native performance to rn in clod VMs >2x improvement for many DB and OLTP applications 5

6 Accelerated Networking Internals: SR-IOV SDN/Networking policy applied in software in the host FPGA-based SmartNIC acceleration sed to apply all policies 6

7 The Need for Serviceability Spport migration of VMs Host pdates inclding PF driver pdates Completely transparent to the VM network stack Completely transparent to the DPDK applications 7

11 Ignite DPDK Developer Preview Lanched prodction DPDK access to select registered developers at Ignite (September 2017) based on Got lots of great feedback from the commnity Demo: A10 vthnder appliance rnning over DPDK on Azre at 30Gbps line-rate 11

12 New Annoncement - DPDK Pblic Preview! DPDK capable VMs are now available in Canada East! All Accelerated Networking VM sizes spported 4+ core VMs Look for additional region availability and GA in the coming months! We want to work with the commnity to find ways to make servicing and migration completely transparent to DPDK applications Developers - Please try DPDK on Azre and give s feedback!
