In the next post we’ll look at the detailed analysis of how a team at Etsy handled a particular incident on December 4th 2014, to see what we can learn from it. The Internet itself, over which these systems operate, is a dynamically distributed network spanning national borders and policies with no central coordinating agent.

Although a beta version was released in 2014, the first stable release of Kubernetes was just made available in September 2018. The result was Kubernetes, which allows developers to create and manage “clusters” of physical and virtual machines in order to coordinate cooperation via a shared network.

Many of the software programs have a web version in some form or other. Web apps allow you to break the traditional constraints of the desktop and mobile operating systems and provide freedom to experiment with different varieties of software. Absence of Virtual DOM results in less memory intensive applications.

They use third-party software like Docker or Kubernetes to simplify their administration. There are workarounds: I can use the perf_events cgroup ID, provided the container software is configuring it (they do). At my employer we sometimes use SR-IOV for direct network interface access, and NVMe for direct disk access.
