Scale Testing Docker Swarm to 30,000 Containers

Swarm is the easiest way to run Docker app in production. It lets you take an an app that youâ€™ve built in development and deploy it across a cluster of servers. Recently we took Swarm out beta and released version 1.0. Itâ€™s being used by people like Oâ€™Reilly for building authoring tools, the Distributed Systems Group at Eurecom for doing scientific research, and Rackspace who built their new container service, Carina, on top of it.

But thereâ€™s an important thing that Swarm needs to be able to do to take your apps to production: it needs to scale. We believed Swarm could scale up tremendously, so we looked around for a benchmark and found one here. We decided to recreate the Kubernetes test with Swarm. Like the team at Google, we wanted to make sure that as we launched more containers it would keep scheduling containers quickly.

Sometimes, we need to completely and irreversibly wipe all data contained in a disk to keep them from falling into the wrong hands. This may not be something we are doing on a day to day basis, but if you want to do it, you should do it right and ensure that the data cannot be recovered by experts. One of the many ways of doing this is through Darik’s Boot and Nuke bootable live CD. This tool is made from the same team that develops the professional-grade Blancco data eraser, only it is available for free and without guarantee or support. The reason I like DBaN is because it is very simple to use and does the job fast.

Minibian “Jessie,” a Linux distribution developed for all the available Raspberry Pi devices, has arrived and is now ready for download.

The latest TOP500 list was published today in conjunction with SC15 in Austin. For the sixth consecutive time, the Tianhe-2 supercomputer in China has retained its position as the world’s No. 1 system. “In the bigger picture, China nearly tripled the number of systems on the latest list, while the number of systems in the United States has fallen to the lowest point since the TOP500 list was created in 1993. China is also carving out a bigger share as a manufacturer of high performance computers with multiple Chinese manufacturers becoming more active in this field.”
