- 4. 4 The Need for DPDK in the Cloud u As customers migrate on-prem networks and apps to the cloud, NFV has become wildly popular u Popular appliances in Azure Marketplace: Load Balancing, L7 filtering, web application firewalls, application gateways, DDoS protection, SD-WAN, and more u DPDK can improve performance, throughput, latency, and reliability for this important class of workloads u Goal: How can we make DPDK appliances work well in the public cloud?
- 5. 5 Azure Accelerated Networking: Fastest Cloud Network! u Highest bandwidth VMs of any cloud u Up to 30Gbps for full-sized regular compute VMs u Standard Linux VM with CUBIC gets 30+Gbps on a single connection u Consistent low latency network performance u Provides SR-IOV to the VM u Up to 10x latency improvement – as low as sub-10us within tenants u Increased packets per second (PPS) u Reduced jitter means more consistency in workloads u Enables workloads requiring native performance to run in cloud VMs u >2x improvement for many DB and OLTP applications
- 7. 7 The Need for Serviceability u Support migration of VMs u Host updates including PF driver updates u Completely transparent to the VM network stack u Completely transparent to the DPDK applications
