VMware ThinApp (formerly Thinstall) is an application virtualization and portable application creator suite by VMware that can package conventional Windows applications [3] into portable applications capable of running on another operating system. According to VMware, the product has a success rate of about 90–95% in packaging applications.
The project maintains around 100 virtual appliances, all freely licensed, with daily automatic security updates and backup capabilities. [2] They are packaged in formats for different virtualization platforms, and two builds for installing onto physical media (to non-virtualized hard disk or USB from a hybrid ISO) or onto the Amazon Elastic Compute Cloud.
Installation of a software appliance on a virtual machine and packaging that into an image creates a virtual appliance. Like software appliances, virtual appliances are intended to eliminate the installation, configuration and maintenance costs associated with running complex stacks of software.
The user can independently configure each VM and run it under a choice of software-based virtualization or hardware assisted virtualization if the underlying host hardware supports this. The host OS and guest OSs and applications can communicate with each other through a number of mechanisms including a common clipboard and a virtualized ...
The first layer virtualization is provided by the Processor Resource and System Manager to deploy one or more Logical Partitions (LPARs). Each LPAR supports a variety of operating systems, including Linux on IBM Z. A hypervisor called z/VM can also be run as the second layer virtualization in LPARs. This allows an LPAR to run as many virtual ...
Nested virtualization becomes more necessary as widespread operating systems gain built-in hypervisor functionality, which in a virtualized environment can be used only if the surrounding hypervisor supports nested virtualization; for example, Windows 7 is capable of running Windows XP applications inside a built-in virtual machine.
[28] [29] If a Proxmox node becomes unavailable or fails, the virtual servers can be automatically moved to another node and restarted. [30] The database and FUSE -based Proxmox Cluster filesystem (pmxcfs [ 31 ] ) makes it possible to perform the configuration of each cluster node via the Corosync communication stack with SQLite engine.
In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.
