What is chaos engineering?

Dynatrace

In 2010, Netflix introduced a technology to switch production software instances off at random — like setting a monkey loose in a server room — to test how the cloud handled its services. Because it can touch many systems, chaos engineering can have broad implications, affecting groups and stakeholders across the organization.

The evolution of single-core bandwidth in multicore processors

John McCalpin

For most high-end processors these values have remained in the range of 75% to 85% of the peak DRAM bandwidth of the system over the past 15-20 years — an amazing accomplishment given the increase in core count (with its associated cache coherence issues), number of DRAM channels, and ever-increasing pipelining of the DRAMs themselves.

USENIX LISA2021 Computing Performance: On the Horizon

Brendan Gregg

This was a chance to talk about other things I've been working on, such as the present and future of hardware performance. I also wrote about these topics in detail for my recent [Systems Performance 2nd Edition] book. Note that my predictions in this talk may be wrong, but they should be thought provoking. Ford, et al., “TCP

USENIX SREcon APAC 2022: Computing Performance: What's on the Horizon

Brendan Gregg

This talk originated from my updates to [Systems Performance 2nd Edition], and this was the first time I've given this talk in person! CXL in a way allows a custom memory controller to be added to a system, to increase memory capacity, bandwidth, and overall performance. Ford, et al., “TCP

Platform Engineering Teams Done Right…

Adrian Cockcroft

We used this model effectively at Netflix when I was their cloud architect from 2010 through 2013. The layers of platforms start at the bottom with hardware choices such as which CPU architectures and vendors you want to use. The next layer is operating system platforms, what flavor of Linux, what version of Windows etc.

Why Browsers Get Built

Alex Russell

In both cases, the OS will task the browser team to heavily prioritise integrations with the latest OS and hardware features at the expense of more broadly useful capabilities — e.g. shipping "notch" CSS and "force touch" events while neglecting Push. Examples include IE 7+ and Safari from 2010-onward.
