Virtualized Networking Acceleration Technologies - Part II

In Part I of this series of posts, I recapped my research on these virtualized networking technologies, with the aim to build an understanding of:

• what they are
• the history and evolution between them

What I did not cover, was a couple of further questions:

1. When to Use Them
2. Can you Combine Them?

This link is a fantastic link that discusses item number one. Now, I can't tell how "right" or "accurate" he is, and I typically look down in comments for rebuttals and refutes (I didn't see any and most commenters seemed relatively uninformed on this topic).

He concludes that in East-West (inter-data center) traffic, DPDK wins, and in North-South traffic, SR-IOV wins.
