Culling The Community
By now, you may have seen some bit of drama in the VMUG community around the apparent policy change that disqualified some VMUG leaders based on their employer. Eric Shanks (@Eric_Shanks) did a great job of covering it on his blog as did Matt Crape (@MattThatITGuy)with his post. While the VMUG situation has its own unique aspects, the question for me boils down to something simple: How do you remove people from an external community?
Babies And Bathwater
Removing unauthorized people from a community is nothing new under the sun. I was a Cisco Champion once upon a time. During the program’s second year I participated in briefings and events with the rest of the group, including my good friend Amy Arnold (@AmyEngineer). When the time came to reapply to the program for Year 3, I declined to apply again for my own reasons. Amy, however, was told that she couldn’t reapply. She and several other folks in the program were being disqualified for “reasons”. It actually took us a while to figure out why, and the answer still wasn’t 100% clear. To this day the best we can figure out is that Continue reading

InfraKit Under the Hood: High Availability
Back in October, Docker released Infrakit, an open source toolkit for creating and managing declarative, self-healing infrastructure. This is the first in a two part series that dives more deeply into the internals of InfraKit.
Introduction
At Docker, our mission to build tools of mass innovation constantly challenges to look at ways to improve the way developers and operators work. Docker Engine with integrated orchestration via Swarm mode have greatly simplified and improved efficiency in application deployment and management of microservices. Going a level deeper, we asked ourselves if we could improve the lives of operators by making tools to simplify and automate orchestration of infrastructure resources. This led us to open source InfraKit, as set of building blocks for creating self-healing and self-managing systems.
There are articles and tutorials (such as this, and this) to help you get acquainted with InfraKit. InfraKit is made up of a set of components which actively manage infrastructure resources based on a declarative specification. These active agents continuously monitor and reconcile differences between your specification and actual infrastructure state. So far, we have implemented the functionality of scaling groups to support the creation of a compute cluster or Continue reading
