Product recommendation

Unidesk4 This product has just been in the past Citrix Synergy to get the best Citrix Synergy Award. The product is the leading provider of open Virtual desktop management software, going mainly about desktop tiering - elastic tiering, layered release mirroring.

          Simply put, layering delimited and drive. it control and save as read-only, virtual disks can be shared across multiple virtual machines. The personalization layer is a virtual disk that captures all desktop-specific settings, as well as data and user-installed applications. Advanced file system and Registry virtualization technologies allocate and merge these layers, rendering a virtual : drive to windows as a single mirror, and make sure that each layer is sequentially or federated interop as if they were installed locally.

If you don't understand, then you can go and see Docker The Federated file system, this Docker The design idea of the federated file system is consistent or is this kind of management software that is based on the federated file system design.

below I quote before Docker the file system described in the article describes this layered technology:

Docker file system belongs to one of the federated file systems. Federated file System): The Federated file system is a layered, lightweight, and high-performance file system that supports file system modifications as a layer of overlay on a single commit, while simultaneously mounting different directories under the same virtual file system (Unite Severaldirectories to a single virtual filesystem).

The Federated file system defines the read-only section asImage, then what isImage? Imagewe can understand that in fact it is a file system that defines what kind of operating system we need to run the program and what software support is required. Imageis actuallyDockerwhen running,Dockerwill automatically help us to provide such operating system and software operation support. The operating system provided is, of course, mirror-level. We say that each container must have an operating system under normal conditions, butDockerthe captured image is just a mirror, not an operating system in the sense. is a very small file, for example ourDockerrun onUbuntusystem, now grab aDockerof theImage, which is stored inside theUbuntuThe system image is also20MBaround. But on a real physical machine, install aUbuntuthe system may need to1GBabout the look. On the other hand, we canUbuntuImage plus you run it on the basis of this imageContainerservices, such asMySQLdatabase. In other words, we want toRunaDocker, you have to haveImage,Imagethere has to be a nest system image and the application software we said to install, so we can say,Imageis the most basic operating system+Software Operating Environment+our own installation of the program. This means that our own programs must be part of the image package.

Imagesimilar to a single-linked list system, eachLmagecontains a pointer toParent Imagethe pointer. NoParent Imageof theImageis aBase Image. In other words, it is layered, one layer at a level, and one for each level .Image. It's a layer above it. ImageIt can be pointed to the bottom layer of theImage.

For example, this figure showsBaseimageit's installed inside.debionthe operation of the system, the above layer ofImageThe integrated development environment is installedEmocs, and then up, the installation isApache, the topmost layer is a writable one. Can be written to be dependent on its underlying content, i.e., if we need to modifyApacheconfiguration, then we need to modify it in a writable layer, with its lower-level installedApacheWill not be modified by itself, but will be copied completely to the top layer, modifying the modified part. The technology used in this process is the technology of storageCoW(copy on Write).
