Hyper-V Containers combine virtualization with containerization

Containers are all the rage these days. You’re just not cool if you’re not using Docker or some other container technology to build and deploy your IT infrastructure. Traditional containers, however, lack sufficient security for some industries and companies, so Microsoft developed Hyper-V Containers.

Container platforms like Docker and Rocket have significant momentum and have quickly become established as a de facto way of developing and deploying applications. Microsoft already entered into an arrangement to bring native Docker container support to Windows Server, but now it is going a step farther by creating Hyper-V Containers that combine the agility of containers with the security of virtualization.

Hyper-V Containers ensure that code running in one container object remains completely isolated. The Hyper-V Container object cannot impact other container objects or the host operating system, or vice versa, because it is a separate virtualized container. Mike Neil, general manager of Windows Server for Microsoft, explained in a blog post, “Leveraging our deep virtualization experience, Microsoft will now offer containers with a new level of isolation previously reserved only for fully dedicated physical or virtual machines, while maintaining an agile and efficient experience with full Docker cross-platform integration.”

IT admins will appreciate the fact that Hyper-V Containers can be created and deployed using the same development and management tools used for traditional Windows Server Containers and that they integrate with Docker for cross-platform deployment. Neil points out that applications developed as Windows Server Containers can easily be deployed as Hyper-V Containers without any modification—enabling organizations to take existing containerized apps and re-deploy them in a more secure manner.

It seems like security is always an afterthought to any new technology concept, and containers is no exception. It started out as a good idea that caught fire, but it wasn’t until it hit critical mass and achieved mainstream adoption that security became a factor. As larger companies, or organizations in highly-regulated industries look at jumping on the container bandwagon, though, security becomes a mandatory component.

Virtualization has been used in hosted environments for years as a means of isolating different systems running on the same physical hardware or network. Microsoft’s Hyper-V Containers take those same principles and apply them at the container app level so that security-conscious organizations can have some peace of mind and remain compliant with security mandates as they embrace containerization.

Microsoft’s strategy of integrating Windows Server Containers and native Docker support in Windows Server and Azure was a big step in the right direction. Adding the security of Hyper-V Containers is brilliant. Microsoft is doing an excellent job of pivoting its business model and not just embracing cloud and DevOps technologies, but raising the bar and taking the lead.

As a side note Microsoft also announced Nano Server—a new minimal footprint implementation of Windows Server optimized for cloud hosting and container technologies. The Nano Server installation includes the bare minimum components necessary. Microsoft claims the result is smaller server images, faster deployment times, decreased network bandwidth consumption, and reduced administrative overhead. In other words a Nano Server installation of Windows Server will just do what it’s supposed to do with minimal interaction or oversight so IT personnel can focus on more important things like the Hyper-V Container apps running on it.

  • Is this marketecture / vaporware, or has anyone really seen this run? I’m intrigued by the possibilities, but it would help me gauge potential to see an example blueprint or proof of concept architecture for a (at least pseudo-) real world workload.

  • Hyper-V containers aren’t really containers though, are they… At 550+MB (Nano Server), and including a Kernel, are they just another variation of VM with Docker API added (to cater for non-Windows DevOps)?
