I joined Netflix in 2014, a company at the forefront of cloud computing with an attractive [work culture]. I could help not only Netflix but all customers of the cloud. Netflix has been the best job of my career so far, and I'll miss my colleagues and the culture. offer letter logo (2014). flame graphs (2014). eBPF tools (2014-2019).

Hacking with AWS at The Next Web Hackaton. Over the past years The Next Web Conference has become a premier conference on internet life and its technologies. I have been to the conference almost every year and it is getting better every time. Amsterdam is of course the ideal place for such a conference :-).

It's an exciting time for developments in computer performance, not just for the BPF technology (which I often [write about]) but also for processors with 3D stacking and cloud vendor CPUs (e.g., Ford, et al., “TCP on Upcoming Sapphire Rapids CPUs,” [link] Oct 2020 - [Liu 20] Linda Liu, “Samsung QVO vs EVO vs PRO: What’s the Difference?

This included SysAdmin magazine, which contained articles from various experts including Amy Rich, and a couple of advertisements: One was to submit your own articles to the magazine for publication (by writing to the editor, Rikki Endsley) and another was to attend USENIX conferences in the US and learn directly from the experts!

Some in-depth and unusual client work (want to encrypt a petabyte of S3 storage? We’ll get to all of those later on, but first I’m going to start the news this time with a roundup of an interesting day last week… News from the Serverless World Keynote Stage at Velocity 2018 Last week I was at O’Reilly’s Velocity conference in San Jose.

I don’t need more bandwidth for video conferences or movies, but I would like to be able to download operating system updates and other large items in seconds rather than minutes. What would the world look like if all of our storage was in the cloud, and access to that storage was so fast we didn’t care? Upcoming events.

With existing customers I get a change to dive deep on their AWS usage and understand what works well and where we can do better. Visiting future customers is equally exiting as you get a change to understand their current architecture, if it is a migration, and how they plan to exploit cloud services in their new setup.

I saw Erik Fisher last time I was in Budapest, and Constantin Gonzalez later became one of the first AWS solutions architects in Germany, too many names to mention. I also applied Six Sigma to capacity planning and presented this at a conference in 2003. He hasn’t changed. So many global friendships were made that continue to today.

Xen's biggest user is the Amazon EC2 cloud, which has over one million customers, and appears to be a custom version (it self identifies as version "3.4.3.amazon"). The way the cloud is used helps with security: most instances at my employer have only been up for one or two days. Oracle VM Server is based on Xen.

It would take 5–10 minutes after the problem occurred to appear as a problem, then people have to notice and respond to emails or pager text messages, dial into a conference call, and log in to monitoring dashboards before any human response can start. This is why most AWS regions have three availability zones.

The success of our early results with the Dynamo database encouraged us to write Amazon's Dynamo whitepaper and share it at the 2007 ACM Symposium on Operating Systems Principles (SOSP conference), so that others in the industry could benefit.
