Solution Stack
In computing, a solution stack or software stack is a set of software subsystems or components needed to create a complete platform such that no additional software is needed to support applications. Applications are said to "run on" or "run on top of" the resulting platform. For example, to develop a web application, the architect defines the stack as the target operating system, web server, database, and programming language. Another version of a software stack is operating system, middleware, database, and applications. Regularly, the components of a software stack are developed by different developers independently from one another. Some components/subsystems of an overall system are chosen together often enough that the particular set is referred to by a name representing the whole, rather than by naming the parts. Typically, the name is an acronym representing the individual components. The term "solution stack" has, historically, occasionally included hardware compone ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computer, computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both computer hardware, hardware and software. Computing has scientific, engineering, mathematical, technological, and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology, and software engineering. The term ''computing'' is also synonymous with counting and calculation, calculating. In earlier times, it was used in reference to the action performed by Mechanical computer, mechanical computing machines, and before that, to Computer (occupation), human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. ...

Linux
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an kernel (operating system), operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically package manager, packaged as a Linux distribution (distro), which includes the kernel and supporting system software and library (computing), libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. List of Linux distributions, Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free ...

MySQL
MySQL () is an Open-source software, open-source relational database management system (RDBMS). Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, and "SQL", the acronym for Structured Query Language. A relational database organizes data into one or more data tables in which data may be related to each other; these relations help structure the data. SQL is a language that programmers use to create, modify and extract data from the relational database, as well as control user access to the database. In addition to relational databases and SQL, an RDBMS like MySQL works with an operating system to implement a relational database in a computer's storage system, manages users, allows for network access and facilitates testing database integrity and creation of backups. MySQL is free and open-source software under the terms of the GNU General Public License, and is also available under a variety of proprietary software, proprietary licenses. MySQ ...

LAMP (software Bundle)
A LAMP (Linux, Apache, MySQL, Perl/PHP/Python) is one of the most common software stacks for the web's most popular web application, applications. Its generic software stack model has largely interchangeable components. Each letter in the acronym stands for one of its four open-source software, open-source building blocks: * Linux for the operating system * Apache HTTP Server * Maria DB or MySQL for the Relational database#RDBMS, relational database management system * Perl, PHP, or Python (programming language), Python for the programming language The components of the LAMP stack are present in the software repository, software repositories of most Linux distributions. History The acronym LAMP was coined by Michael Kunze in the December 1998 issue of ''Computertechnik'', a German computing magazine, as he demonstrated that a bundle of free and open-source software "could be a feasible alternative to expensive commercial packages". Since then, O'Reilly Media and MySQL teamed u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seaside Web Framework
Seaside, an acronym that stands for “Squeak Enterprise Aubergines Server with Integrated Development Environment,” is computer software, a web framework to develop web applications in the programming language Smalltalk. It is distributed as free and open-source software under an MIT License. Seaside provides a component architecture in which web pages are built as trees of individual, stateful components, each encapsulating a small part of a page. Seaside uses continuations to model multiple independent flows between different components. Thus, it is a continuation-based web framework based on the ability to manipulate the execution stack of some implementations of Smalltalk. Key features Although subsequent improvement of state handling in web browser JavaScript engines have meant this aspect is less important today, Seaside's method of handling of browser state (via continuations) was an initial point of interest in the first years following its 2002 release.

Apache HTTP Server
The Apache HTTP Server ( ) is a free and open-source software, free and open-source cross-platform web server, released under the terms of Apache License, Apache License 2.0. It is developed and maintained by a community of developers under the auspices of the Apache Software Foundation. The vast majority of Apache HTTP Server instances run on a Linux distribution, but current versions also run on Microsoft Windows, OpenVMS, and a wide variety of Unix-like systems. Past versions also ran on NetWare, OS/2 and other operating systems, including ports to mainframes. Originally based on the NCSA HTTPd server, development of Apache began in early 1995 after work on the NCSA code stalled. Apache played a key role in the initial growth of the World Wide Web, quickly overtaking NCSA HTTPd as the dominant HTTP server. In 2009, it became the first web server software to serve more than 100 million websites. , Netcraft estimated that Apache served 17.83% of the million busiest websites, w ...

Cluster Manager
Within cluster and parallel computing, a cluster manager is usually backend graphical user interface (GUI) or command-line interface (CLI) software that runs on a set of cluster nodes that it manages (in some cases it runs on a different server or cluster of management servers). The cluster manager works together with a cluster management agent. These agents run on each node of the cluster to manage and configure services, a set of services, or to manage and configure the complete cluster server itself (see supercomputing.) In some cases the cluster manager is mostly used to dispatch work for the cluster (or cloud) to perform. In this last case a subset of the cluster manager can be a remote desktop application that is used not for configuration but just to send work and get back work results from a cluster. In other cases the cluster is more related to availability In reliability engineering, the term availability has the following meanings: * The degree to which a system, sub ...

Virtual Machine
In computing, a virtual machine (VM) is the virtualization or emulator, emulation of a computer system. Virtual machines are based on computer architectures and provide the functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination of the two. Virtual machines differ and are organized by their function, shown here: * ''System virtual machines'' (also called full virtualization VMs, or SysVMs) provide a substitute for a real machine. They provide the functionality needed to execute entire operating systems. A hypervisor uses native code, native execution to share and manage hardware, allowing for multiple environments that are isolated from one another yet exist on the same physical machine. Modern hypervisors use hardware-assisted virtualization, with virtualization-specific hardware features on the host CPUs providing assistance to hypervisors. * ''Process virtual machines'' are designed to execute computer programs ...

Ganeti
Ganeti is a virtual machine cluster management tool originally developed by Google. The solution stack uses either Xen, KVM, or LXC as the virtualization platform, LVM for disk management, and optionally DRBD for disk replication across physical hosts or shared storage for external replication. Since 2007 Ganeti is developed and released as free and open-source software. Originally subject to the requirements of the GNU General Public License (GPL) version 2, the license was changed to the 2-clause BSD license in version 2.11.6, released September 2014. Ganeti acts as a convenient wrapper around existing hypervisors for system administrators to set up a cluster. It is used by Google for some of its computing infrastructure and also by the Linux Foundation (formerly Open Source Development Labs) for hosting open source projects. In contrast to cloud solutions designed for many ephemeral VMs, Ganeti focuses on long-lived, persistent VMs suitable for workloads that don't have b ...
