Docker containers and the next generation of virtualization

This year, LinuxCon and ContainerCon attendees will have the opportunity to hear Jerome Petazzoni speak on Docker, Containers & Security: State Of Union. Jerome works at Docker Inc., where he helps others to containerize all the things. Jerome has worked in miscellaneous technical fields, including VOIP, embedded systems, web hosting, virtualization and cloud computing.

From a high-level point of view, containers look like lightweight virtual machines. You can install whatever you want in a container, independently from (and without affecting!) other containers or the host environment. Each container has its own network stack, process (PID) space, file system, etc. And their footprint is significantly smaller than VMs: containers start faster, and they require less memory and disk space. This is because from a low-level point of view, containers are just regular processes on the host machine, using kernel features like namespaces and control groups to provide the isolation. Starting a container is just starting a regular UNIX process; creating a container is just cloning a snapshot of a copy-on-write filesystem (which is extremely cheap nowadays, both in time and disk usage).

Moving on from Akamai.

Today was my last day at Akamai. It’s been brief (Just over seven months), but things weren’t really working out for me there for a number of reasons. I’ve mentioned to a number of people who have known about my decision for a while, that it’s not that it’s a bad place to work, but it never felt like a good fit for me, and I came to realize that I’ve spent most of this last year being in denial of just how unhappy I was, in the hope “things would get better”.
