Windows Containers – What is it and why should we care?

This post is originally published as article within SDN Magazine on February 28th, 2017. One of the hot topics within the Microsoft development community right now is undoubtedly the “container” topic. Following the success of both Docker and containers on Linux, Microsoft developed a Windows container implementation on Windows Server 2016 and Windows 10. After two and a half years of development plus one year of running this container technology in preview for insiders (Windows Server 2016 TP3 – TP5), September of 2016 finally saw Microsoft’s announcement that it had released Windows Server 2016 to the public. While the container technology and Containerized Delivery have been used by non-Microsoft focused enterprises for a few years now (Linux has had its container technology since August 2008), the Microsoft community is only at the beginning of this new journey. This is, therefore, the perfect moment to ask ourselves whether we should care about Windows containers, and whether we should look

Deep dive into Windows Server Containers and Docker – Part 3 – Underlying implementation of Hyper-V Containers

Last April I visited DockerCon 2017 and while they announced many new great things like the LinuxKit and the Moby Project, one of the most appealing announcements for me definitely was the announcement of John Gossman that Microsoft and Docker made it possible to run Linux containers natively on Windows Hosts by using the same Hyper-V isolation layer as Hyper-V containers. So, time for me to create a blogpost about Hyper-V containers and to explain how this Hyper-V container virtualization layer works. In the previous blogpost of this series, we learned about the difference between containers and VMs and even Windows and Linux containers. Where Linux hosts only support one type of containers: Linux containers, Windows hosts do support multiple container types like Windows Server containers, Hyper-V containers and even Linux containers. Let’s dive into the Hyper-V container technology. Normal Windows Server Containers Even though normal Windows Server Containers have great benefits like instant-startup times
