During our annual Perform event, CEO John Van Siclen explained how several years ago – whilst at a dinner in Linz – we saw the cloud coming, and that it would disrupt everything, meaning monitoring alone would no longer be enough. We’re spearheading the move to the cloud, the disruption, and we want you to continue with us on that journey.

Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. At Netflix, we've been using these technologies as they've been made available for instance types in the AWS EC2 cloud. AWS called this [enhanced networking]. The first was c3.

Load averages are an industry-critical metric – my company spends millions auto-scaling cloud instances based on them and other metrics – but on Linux there's some mystery around them. They can be also useful when a single value of demand is desired, such as for a cloud auto scaling rule. Network I/O?
