Software Appliances
A software appliance is a software application combined with just enough operating system (JeOS) to run optimally on industry-standard hardware (typically a server) or in a virtual machine. It is a software distribution or firmware that implements a computer appliance. Virtual appliances are a subset of software appliances. The main distinction is the packaging format and the specificity of the target platform. A virtual appliance is a virtual machine image designed to run on a specific virtualization platform, while a software appliance is often packaged in more generally applicable image format (e.g., Live CD) that supports installations to physical machines and multiple types of virtual machines.Wu C F, Wang Y S, Liu G N, Amies, A, 2012Create solutions on IBM SmartCloud Enterprise: Transfer image assets between different accounts''IBM developerWorks'', June 6.

Firmware
In computing, firmware is a specific class of computer software that provides the low-level control for a device's specific hardware. Firmware, such as the BIOS of a personal computer, may contain basic functions of a device, and may provide hardware abstraction services to higher-level software such as operating systems. For less complex devices, firmware may act as the device's complete operating system, performing all control, monitoring and data manipulation functions. Typical examples of devices containing firmware are embedded systems (running embedded software), home and personal-use appliances, computers, and computer peripherals. Firmware is held in non-volatile memory devices such as ROM, EPROM, EEPROM, and flash memory. Updating firmware requires ROM integrated circuits to be physically replaced, or EPROM or flash memory to be reprogrammed through a special procedure. Some firmware memory devices are permanently installed and cannot be changed after manufacture. C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Bloat
Software bloat is a process whereby successive versions of a computer program become perceptibly slower, use more memory, disk space or processing power, or have higher hardware requirements than the previous version, while making only dubious user-perceptible improvements or suffering from feature creep. The term is not applied consistently; it is often used as a pejorative by end users (bloatware) to describe undesired user interface changes even if those changes had little or no effect on the hardware requirements. In long-lived software, perceived bloat can occur from the software servicing a large, diverse marketplace with many differing requirements. Most end users will feel they only need some limited subset of the available functions, and will regard the others as unnecessary bloat, even if end users with different requirements require those functions. Actual (measurable) bloat can occur due to de-emphasising algorithmic efficiency in favour of other concerns like developer ...

Software Distribution
Software distribution is the process of delivering software to the end user. A distro is a collection of software components built, assembled and configured so that it can essentially be used "as is". It is often the closest thing to turnkey form of free software. A distro may take the form of a ''binary distribution'', with an executable installer which can be downloaded from the Internet. Examples range from whole operating system distributions to server and interpreter distributions (for example WAMP installers). ''Software distribution'' can also refer to careware and donateware. In recent years, the term has come to refer to nearly any "finished" software (i.e. something that is more or less ready for its intended use, whether as a complete system or a component of a larger system) that is assembled primarily from open source components. Examples of distros Examples of software distributions include BSD-based distros (such as FreeBSD, NetBSD, OpenBSD, and DragonflyBSD) an ...

Windows To Go
Windows To Go is a feature in Windows 8 Enterprise, Windows 8.1 Enterprise, Windows 10 Education and Windows 10 Enterprise versions prior to the May 2020 update, that allows the system to boot and run from certain USB mass storage devices such as USB flash drives and external hard disk drives which have been certified by Microsoft as compatible. It is a fully manageable corporate Windows environment. The development of Windows To Go was discontinued by Microsoft in 2019, and is no longer available in Windows 10 as of the May 2020 update (version 2004). It was intended to allow enterprise administrators to provide users with an imaged version of Windows that reflects the corporate desktop. Although creation of Windows To Go drives was not officially supported by non-Enterprise (or Education) editions of Windows 8.x and 10, some information has been published describing various ways to install Windows To Go using any edition of Windows 8.x and 10 and any bootable USB device.

SUSE Studio
SUSE Studio was an online Linux software creation tool by SUSE. Users could develop their own Linux distro, software appliance, or virtual appliance, mainly choosing which applications and packages they want on their "custom" Linux and how it looks. Users could choose between openSUSE or SUSE Linux Enterprise as a base and pick from a variety of pre-configured images including jeOS, minimal server, GNOME, and KDE desktops. The SUSE Studio service was shut down on February 15, 2018. Image formats and booting options SUSE Studio supports the following image formats and booting options: * Live CD/DVD / ISO image * VMDK (VMware disk image) * VirtualBox * VHD (Virtual Hard Disk) * arddisk image * USB image * Xen * KVM (Kernel-based Virtual Machine) * OVF (Open Virtualization Format) * AMI (Amazon Machine Image) for Amazon Elastic Compute Cloud * Preboot Execution Environment (onsite version only) SUSE Studio in use OSUSE Galleryone can find a catalog of the images created i ...

TurnKey Linux Virtual Appliance Library
The TurnKey Linux Virtual Appliance Library is a free open-source software project which develops a range of Debian-based pre-packaged server software appliances (also called virtual appliances). Turnkey appliances can be deployed as a virtual machine (a range of hypervisors are supported), in cloud computing services such as Amazon Web Services or installed in physical computers. Features The project maintains around 100 virtual appliances, all freely licensed, with daily automatic security updates and backup capabilities. 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. * Virtual appliances distributed as virtual machine types such as: ** Open Virtualization Format (OVA) - As of v14.0 was the default VM format.

Portable Application
A portable application (portable app), sometimes also called standalone, is a program designed to read and write its configuration settings into an accessible folder in the computer, usually in the folder where the portable application can be found. This makes it easier to transfer the program with the user's preferences and data between different computers. A program that doesn't have any configuration options can also be a portable application. Portable applications can be stored on any data storage device, including internal mass storage, a file share, cloud storage or external storage such as USB drives and floppy disks—storing its program files and any configuration information and data on the storage medium alone. If no configuration information is required a portable program can be run from read-only storage such as CD-ROMs and DVD-ROMs. Some applications are available in both installable and portable versions. Some applications which are not portable by default do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software As A Service
Software as a service (SaaS ) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted. SaaS is also known as "on-demand software" and Web-based/Web-hosted software. SaaS is considered to be part of cloud computing, along with infrastructure as a service (IaaS), platform as a service (PaaS), desktop as a service (DaaS), managed software as a service (MSaaS), mobile backend as a service (MBaaS), data center as a service (DCaaS), integration platform as a service (iPaaS), and information technology management as a service (ITMaaS). SaaS apps are typically accessed by users of a web browser (a thin client). SaaS became a common delivery model for many business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization, accounting, collaboration, customer relationship management (CR ...

Docker (software)
Docker is a set of platform as a service (PaaS) products that use OS-level virtualization to deliver software in packages called ''containers''. The service has both free and premium tiers. The software that hosts the containers is called Docker Engine. It was first started in 2013 and is developed by Docker, Inc. Background Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels. Because all of the containers share the services of a single operating system kernel, they use fewer resources than virtual machines. Operation Docker can package an application and its dependencies in a virtual container that can run on any Linux, Windows, or macOS computer. This enables the application to run in a variety of locations, such as on-premises, in public (see decentralized computing, distributed computing, and cloud computing) or private cloud. When running on Linux, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Container (virtualization)
OS-level virtualization is an operating system (OS) paradigm in which the kernel allows the existence of multiple isolated user space instances, called ''containers'' ( LXC, Solaris containers, Docker, Podman), ''zones'' (Solaris containers), ''virtual private servers'' (OpenVZ), ''partitions'', ''virtual environments'' (VEs), ''virtual kernels'' (DragonFly BSD), or ''jails'' (FreeBSD jail or chroot jail). Such instances may look like real computers from the point of view of programs running in them. A computer program running on an ordinary operating system can see all resources (connected devices, files and folders, network shares, CPU power, quantifiable hardware capabilities) of that computer. However, programs running inside of a container can only see the container's contents and devices assigned to the container. On Unix-like operating systems, this feature can be seen as an advanced implementation of the standard chroot mechanism, which changes the apparent root folder ...

Open Virtualization Format
Open Virtualization Format (OVF) is an open standard for packaging and distributing virtual appliances or, more generally, software to be run in virtual machines. The standard describes an "open, secure, portable, efficient and extensible format for the packaging and distribution of software to be run in virtual machines". The OVF standard is not tied to any particular hypervisor or instruction set architecture. The unit of packaging and distribution is a so-called ''OVF Package'' which may contain one or more ''virtual systems'' each of which can be deployed to a virtual machine. History In September 2007 VMware, Dell, HP, IBM, Microsoft and XenSource submitted to the Distributed Management Task Force (DMTF) a proposal for OVF, then named "Open Virtual Machine Format". The DMTF subsequently released the OVF Specification V1.0.0 as a preliminary standard in September, 2008, and V1.1.0 in January, 2010. In January 2013, DMTF released the second version of the standard, OVF 2.0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
