LinuxCon+ContainerCon Europe 2016

Containers must communicate. Without a method for one container to talk to another, let alone the outside world, the overwhelming majority of containers serve little purpose. Yet the networking stack for containers is not well understood, especially in environments with networking performance requirements, such as high performance computing, financial services, or simply those who cannot just throw hardware at a problem.

We will review how containers internetwork, explore multiple networking options for containers, and evaluate the latency and throughput characteristics of each.

Finally, we will look at an actual analysis of each option and the performance results as compared to bare metal, and what lessons we can learn.
