Virtualization

Not necessarily the industry changing, but the maturity of the industry itself.

Virtualization is not new anymore.

Everyone knows how it works.

If I go look

If the hardware is tainted, the game is over before it begins.

Virtualization is the backbone of the cloud, but it creates a massive attack surface.

First, you have VM sprawl.

This happens when you spin up VMs for testing and forget to turn them off.

The FreeBSD approach to exposing SRIOV capabilities is one of several reasons why I prefer FreeBSD on my servers.

Virtualization is a great solution if your demand for network devices exceeds the number of physical network ports on your server.

There may be ways to accomplish this with software.

But a hardware-based alternative is SRIOV, which lets a single physical PCIe device present itself as many to the operating system.
