A Linux distribution is an operating system made from a software collection that includes the Linux kernel and often a package management system. They are often obtained from the website of each distribution, which are available for a wide variety of systems ranging from embedded devices and personal computers to servers and powerful supercomputers.
VSEn is an operating system for IBM mainframe computers, the latest one in the DOS/360 lineage, which originated in 1965. It is less common than z/OS and is mostly used on smaller machines.
A terminal emulator, or terminal application, is a computer program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term terminal covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window.
HCL Notes is a proprietary collaborative software platform for Unix (AIX), IBM i, Windows, Linux, and macOS, sold by HCLTech. The client application is called Notes while the server component is branded HCL Domino.
A Beowulf cluster is a computer cluster of what are normally identical, commodity-grade computers networked into a small local area network with libraries and programs installed which allow processing to be shared among them. The result is a high-performance parallel computing cluster from inexpensive personal computer hardware.
In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
System software is software designed to provide a platform for other software. Examples of system software include operating systems (OS).
A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions on the native hardware. Multiple instances of a variety of operating systems may share the virtualized hardware resources: for example, Linux, Windows, and macOS instances can all run on a single physical x86 machine. This contrasts with operating-system–level virtualization, where all instances must share a single kernel, though the guest operating systems can differ in user space, such as different Linux distributions with the same kernel.
IBM System z9 is a line of IBM mainframe computers. The first models were available on September 16, 2005. The System z9 also marks the end of the previously used eServer zSeries naming convention. It was also the last mainframe computer that NASA ever used.
IBM Storage Protect is a data protection platform that gives enterprises a single point of control and administration for backup and recovery. It is the flagship product in the IBM Spectrum Protect family.
Application virtualization is a software technology that encapsulates computer programs from the underlying operating system on which they are executed. A fully virtualized application is not installed in the traditional sense, although it is still executed as if it were. The application behaves at runtime like it is directly interfacing with the original operating system and all the resources managed by it, but can be isolated or sandboxed to varying degrees.
IBM Lotus Expeditor is a software framework by IBM's Lotus Software division for the construction, integration, and deployment of "managed client applications", which are client applications that are deployed from, configured, and managed onto a desktop, usually by a remote server. The goal is to allow developers to create applications that take advantage of running on a local client, while having the same ease of maintenance as web-based applications.
A virtual security appliance is a computer appliance that runs inside virtual environments. It is called an appliance because it is pre-packaged with a hardened operating system and a security application and runs on a virtualized hardware. The hardware is virtualized using hypervisor technology delivered by companies such as VMware, Citrix and Microsoft. The security application may vary depending on the particular network security vendor. Some vendors such as Reflex Systems have chosen to deliver Intrusion Prevention technology as a Virtualized Appliance, or as a multifunctional server vulnerability shield delivered by Blue Lane. The type of security technology is irrelevant when it comes to the definition of a Virtual Security Appliance and is more relevant when it comes to the performance levels achieved when deploying various types of security as a virtual security appliance. Other issues include visibility into the hypervisor and the virtual network that runs inside.
In computing, virtualization (v12n) is a series of technologies that allows dividing of physical computing resources into a series of virtual machines, operating systems, processes or containers.
Junos OS is a FreeBSD-based network operating system used in Juniper Networks routing, switching and security devices.
Lotus Foundations is a bundled small-business server solutions package by IBM. The package includes Lotus Domino, directory services, file management, firewall, backup, web hosting and various other productivity tools.
WebSphere Portal is an enterprise software used to build and manage web portals. It provides access to web content and applications, while delivering personalized experiences for users.
Leostream, founded in 2002, is a privately held technology company based in Waltham, Massachusetts. Its flagship product is a connection broker for virtual desktop infrastructure (VDI) and resources hosted in the datacenter.
NetVault is a set of data protection software developed and supported by Quest Software. NetVault Backup is a backup and recovery software product. It can be used to protect data and software applications in physical and virtual environments from one central management interface. It supports many servers, application platforms, and protocols such as UNIX, Linux, Microsoft Windows, VMware, Microsoft Hyper-V, Oracle, Sybase, Microsoft SQL Server, NDMP, Oracle ACSLS, IBM DAS/ACI, Microsoft Exchange Server, DB2, and Teradata.
HP ConvergedSystem is a portfolio of system-based products from Hewlett-Packard (HP) that integrates preconfigured IT components into systems for virtualization, cloud computing, big data, collaboration, converged management, and client virtualization. Composed of servers, storage, networking, and integrated software and services, the systems are designed to address the cost and complexity of data center operations and maintenance by pulling the IT components together into a single resource pool so they are easier to manage and faster to deploy. Where previously it would take three to six months from the time of order to get a system up and running, it now reportedly takes as few as 20 days with the HP ConvergedSystem.
