This document discusses Microsoft's container ecosystem. It covers Docker for Windows, Windows containers, Azure Container Service (ACS), and running .NET on Linux. Docker for Windows allows running Docker natively on Windows using Hyper-V. Windows containers leverage the Windows kernel for isolation using namespaces and control groups. ACS simplifies deploying Docker clusters to Azure. .NET Core allows developing .NET applications on Linux. The document also briefly mentions Docker Datacenter and Enterprise DC/OS as enterprise container solutions.
