My last talk for 2017 was at AWS re:Invent, on "How Netflix Tunes EC2 Instances for Performance," an updated version of my [2014] talk. A video of the talk is on youtube : The slides are on slideshare : I love this talk as I get to share more about what the Performance and Operating Systems team at Netflix does, rather than just my work.

EPU: Emotion Processing Unit is designed by Emoshape , as the MCU microchip design to enable a true emotional response in AI, robots and consumer electronic devices as a result of a virtually unlimited cognitive process. In Google I/O’17, Google announced its cloud TPU (also known as TPU2), which can handle both training and inference.

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. Each dimension has progressed through these stages: 1.

Before an organization moves to function as a service, it’s important to understand how it works, its benefits and challenges, its effect on scalability, and why cloud-native observability is essential for attaining peak performance. Cloud providers then manage physical hardware, virtual machines, and web server software management.

According to the 2020 Cloud Native Computing Foundation (CNCF) survey , 92 percent of organizations are using containers in production, and 83 percent of these use Kubernetes as their preferred container management solution. This simplifies orchestration in cloud-native environments. Dynatrace news. But what is Kubernetes exactly?

These strange questions came to the fore back in 2014 when Netflix was switching services from CentOS Linux to Ubuntu, and I helped debug several weird performance issues including one I'll describe here.

The problem is that this system has a default libc that has been compiled without frame pointers, so any stack walking stops at the libc layer, producing a partial stack that's missing the application frames.

Although a beta version was released in 2014, the first stable release of Kubernetes was just made available in September 2018. That’s why Google set out to develop an open source system that would simplify the “deployment, scaling and operations” of containerized applications across multiple hosts.

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. This measures demand, which can be greater than what the system is currently processing. then your system is idle. - 42/3411 43603.
