Using Blue/Green environments to avoid a Gitlab style outage

As most of you are probably aware, Gitlab is, in part, a source code hosting repository which suffered something of a major outage just a few weeks ago. Unusually, they posted a very full and frank report on what actually happened. It’s very rare for a company to do this and even rarer for it to be made public, I wish more companies would do this, even if it was just an internal review with the blame put on the process, it would at least highlight where the weaknesses are in the infrastructure.

Nano Server Image Builder tool
Posted by Romain Serre on November 15, 2016
4.5/5 (2)

Nano Server is a new way to deploy Windows Server in your datacenter or in the Cloud. Nano Server is a low footprint operating system which handles what you need and no more. When you create the Nano Server, you choose the role that you want to add to the image (Hyper-V, Storage, containers and so on). Nano Server doesn’t contain Windows Logon, 32-bit legacy or cannot be managed by GPO.

Currently, I don’t really like Nano Server for some jobs as Hyper-V or storage. Nano Server comes with the Current Branch for Business servicing model. So, to be fully supported, your Nano Server has to be upgraded two or three times in a year. You can imagine what happens with hundreds of Hyper-V/Storage nodes? Anyway, Nano Server can run other jobs as IIS and Containers, and in these cases, it could be fine.

In this topic, I’ll show you how to prepare a Nano Server image which will be deployed in a virtual machine. The operating system will be configured to run containers. To create the Nano Server image, I’ll use the Nano Server Image Builder tool which is a graphical interface to prepare the image in VHD, VHDX or WIM file format.
