Docker containers are all the rage nowadays. We all heard of them - the marvelous new kid on the block which runs on Linux. But what about all of us Windows developers? You know… that OS with the four squares… Who use the FULL .NET framework? Who run on Windows? Who LOVE Windows?? Enter Windows Containers. Windows containers are containers just like the Docker containers you know and love which work with the same Docker tools, but with one BIG difference - they run on Windows! In this one hour session I'll show you what are Windows Containers and how you can use them to easily package and deploy your Windows applications, services, IIS apps and Windows dependencies such as SQL Server to a Windows cluster using standard and familiar Docker tools.
