Andromeda: performance, isolation, and velocity at scale in cloud network virtualization Dalton et al., NSDI’18

Yesterday we took a look at the Microsoft Azure networking stack, today it’s the turn of the Google Cloud Platform. (It’s a very handy coincidence to have two such experience and system design report papers appearing side by side so that we can compare). Andromeda has similar design goals to AccelNet: performance close to hardware, serviceability, and the flexibility and velocity of a software-based architecture. The Google team solve those challenges in a very different way though, being prepared to make use of host cores (which you’ll recall the Azure team wanted to avoid).

We opted for a high-performance software-based architecture instead of a hardware-only solution like SR-IOV because software enables flexible, high-velocity feature deployment… Andromeda consumes a few percent of the CPU and memory on-host. One physical CPU core is reserved for the Andromeda…
