Container Migration Around The World

In this article I want to talk about a runC container which I want to migrate around the world while clients stay connected to the application.

In my previous Checkpoint/Restore In Userspace (CRIU) articles I introduced CRIU (From Checkpoint/Restore to Container Migration) and in the follow-up I gave an example how to use it in combination with containers (Container Live Migration Using runC and CRIU). Recently Christian Horn published an additional article about CRIU which is also a good starting point.

The part that is running in the container is the server part of the game to which multiple clients can connect to play together. In this article the client is running on my local system while the server and its container is live migrated around the world.

This article also gives detailed background information about

The reason came up because he had a “high security” client that needed to keep different traffic types separated within RHV, as the VMs were used to scan live malware. And that is why I made the comment about the (justifiably) paranoid.

Let’s take a look. |

Picking your Deployment Architecture

In the previous post I talked about Smart Card Support in Red Hat Enterprise Linux. In this article I will drill down into how to select the right deployment architecture depending on your constraints, requirements and availability of the smart card related functionality in different versions of Red Hat Enterprise Linux.

To select the right architecture for a deployment where users would authenticate using smart cards when logging into Linux systems you need to
