The growing clouds of (Linux) containers, and their usefulness in teaching and research


Owheo 106 - 1:00 pm, Friday 22 May


Linux container technologies (e.g. Docker, Kubernetes, LXC, etc.) perform virtualisation at the operating system level. While virtualisation over a shared operating system kernel is far from a new idea, Linux containers have been shown to be a good fit for many of today's cloud workloads. Google recently stated that they run "everything" within containers. The lightweight nature of container technology makes Google's workload practical: they start up more than two billion containers per week.

In this talk, after introducing container technology, I will discuss how recent "DevOp" tools, such as Vagrant, are making the management of Linux containers and other virtual machines increasingly straightforward. I will demonstrate how I use containers within my own teaching and research.

Finally, I will explore containers in terms of computer security. I will outline research that employs emerging CPU hardware to provide surprisingly strong security guarantees, despite containers' surface area for attack being larger than that of other forms of hardware virtualisation.
