Know anyone who needs cloud? I wrote Explain the Cloud Like I'm 10 just for them. skamille : I worry that the cloud is just moving us back to a world of proprietary software. BrentToderian : What city went from 14% of all trips by bike in 2001, to 22% by 2012, then leaped to 30% in 3 years by 2015, & 35% by 2018?

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].

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.
