Microsoft is a late arrival to the container approach, but its Windows Containers is a way to provide container services on a Windows platform. Ansible is another container-management system favored by Red Hat. Actually, Docker is a management system that’s used to create, manage, and monitor Linux containers. One of the more popular platforms is Docker, which is now based on Linux libcontainer. For example, each Google Docs service gets a container per user instance.Ī number of container technologies are available, with Linux leading the charge. Containers have been the rage on servers and the cloud, with companies like Facebook and Google investing heavily in container technology. Virtual-machine technology is well-known in the embedded community, but containers tend to be the new kid on the block, so they warrant a bit more coverage in this article. However, it’s possible to have a fixed set of applications in a single container. Typically a VM will host multiple applications whose mix may change over time versus a container that will normally have a single application. Applications running in a container environment share an underlying operating system, while VM systems can run different operating systems. A para-virtualized VM environment provides an abstract hardware abstraction layer (HAL) that requires HAL-specific device drivers.

In a nutshell, a VM provides an abstract machine that uses device drivers targeting the abstract machine, while a container provides an abstract OS. Virtual machines (VM) are managed by a hypervisor and utilize VM hardware (a), while container systems provide operating system services from the underlying host and isolate the applications using virtual-memory hardware (b). Hardware I/O virtualization also allows a single hardware device like an Ethernet adapter to present multiple, virtual instances of itself so that multiple VMs can manage their instance directly.

Some systems allow real hardware to map directly to a VM’s environment, enabling the VM’s device driver to directly handle the hardware. It uses virtual-memory support for isolation, but it requires special device drivers in the VM that are linked through the hypervisor to the underlying operating system, which in turn provides the device services.Ī hardware VM system forces any communication with a VM to go through the hardware. There is also something called para-virtualization, which is sort of a mix between the two approaches. As a result, container services such as file systems or network support can have limited resource access. Container systems usually provide service isolation between containers. Container systems have a lower overhead than VMs and container systems typically target environments where thousands of containers are in play. A hypervisor, on the other hand, runs VMs that have their own operating system using hardware VM support. The container’s system requires an underlying operating system that provides the basic services to all of the containerized applications using virtual-memory support for isolation. Two main differences exist between a container and a hypervisor system. Type 1 hypervisors run on bare metal, while Type 2s have an underlying operating system (see figure, a).Ĭontainers also provide a way to isolate applications and provide a virtual platform for applications to run on (see figure, b). Typically, a VM will run any software that runs on the bare metal hardware while providing isolation from the real hardware. It’s standard fare on server processors like Intel’s Xeon and found on most application processors such as the Arm Cortex-A series. Not all processors have this type of hardware-it’s typically found in mid- to high-end microprocessors. Hypervisors are a way to manage virtual machines (VMs) on processors that support the virtual replication of hardware. Adding an operating system to the mix makes multiple applications easier to work with however, these days even a single operating system isn’t always the best solution. Writing a single application is still manageable for a small microcontroller, but it’s impractical for larger systems that need a more modular approach.
