Windows Containers and Docker

Windows Server 2016 features support for containers. These are not Linux-based, but containers that run on Windows and run Windows on the inside. These conform to the Open Container Initiative (OCI). They allow you to run applications insulated from the rest of the system, within portable containers that include everything an application needs to be fully functional. As they did with Linux, containers will change the nature of the software supply chain for Windows users.… Read more

Christos Matskas shows how an application can interact with the service, using a node.JS application as an example.… Read more

Application Containers For Cloud Computing

Containers promise to make applications more portable and efficient. The technology, originally based on Linux's cgroups, provides a way of running several applications as modular, platform-agnostic packages in isolation on the same server. Docker's open-source approach to containers has dominated the market, and Microsoft is producing its own equivalent Windows system. What next? Will Containers replace VMS? Robert Sheldon investigates.… Read more
