Using DPUs to encrypt traffic per VM
· 7 min read
Motivation
In part one of this series, we showed how to set up an NVIDIA BlueField-2 DPU with the aim of simply using it as a NIC (https://rcblog.erc.monash.edu.au/blog/2022/02/how-do-i-use-a-dpu-as-nic/). Today we’re going to delve a bit deeper and offload network layer encryption to the DPUs so that VMs running on the Host can use more of their allocated resources while still communicating securely.
