Cloud computing Cloud computing metaphor: For a user, the network elements representing the provider-rendered services are invisible, as if obscured by a cloud. Cloud computing is a computing term or metaphor that evolved in the late 1990s, based on utility and consumption of computer resources. Cloud computing involves application systems which are executed within the cloud and operated through internet enabled devices. Purely cloud computing does not rely on the use of cloud storage as it will be removed upon users download action.

UEC This tutorial covers UEC installation from the Ubuntu 10.04 LTS Server Edition CD, and assumes a basic network topology, with a single system serving as the "all-in-one controller", and one or more nodes attached. From this Tutorial you will learn how to install, configure, register and perform several operations on a basic UEC setup that results in a cloud with a one controller "front-end" and one or several node(s) for running Virtual Machine (VM) instances. You will also use examples to help get you started using your own private compute cloud. To deploy a minimal cloud infrastructure, you’ll need at least two dedicated systems: A front end.
Cloud computing In common usage, the term "the cloud" is essentially a metaphor for the Internet. Marketers have further popularized the phrase "in the cloud" to refer to software, platforms and infrastructure that are sold "as a service", i.e. remotely through the Internet. Typically, the seller has actual energy-consuming servers which host products and services from a remote location, so end-users don't have to; they can simply log on to the network without installing anything. The major models of cloud computing service are known as software as a service, platform as a service, and infrastructure as a service. These cloud services may be offered in a public, private or hybrid network. Google, Amazon, IBM, Oracle Cloud, Salesforce, Zoho and Microsoft Azure are some well-known cloud vendors.
Platform as a service Platform as a service (PaaS) is a category of cloud computing services that provides a computing platform and a solution stack as a service. Along with software as a service (SaaS) and infrastructure as a service (IaaS), it is a service model of cloud computing. In this model, the consumer creates the software using tools and/or libraries from the provider. The consumer also controls software deployment and configuration settings. Textpattern Textpattern is an open source content management system originally developed by Dean Allen. While it is often listed among weblogging tools, its aim is to be a general-purpose content management system suitable for deployment in many contexts. Textpattern is written in PHP using a MySQL database backend. The current stable version is Textpattern 4.5.5. History Textpattern grew out of the system used to publish Textism, Allen's personal site, and an unnamed version was announced as available to alpha testers in 2001. In 2003, Textpattern was formally announced. The early alpha versions were followed by a series of beta releases which saw more widespread use, and which were themselves superseded by a series of "gamma" releases which expanded and refined Textpattern's capabilities.
Squid (software) Squid was originally designed to run on Unix-like systems. The Windows port was maintained up to version 2.7 but more current versions are not being developed. Released under the GNU General Public License, Squid is free software. Squid was originally developed as the Harvest object cache, part of the Harvest project at the University of Colorado Boulder. Further work on the program was completed at the University of California, San Diego and funded via two grants from the National Science Foundation. Duane Wessels forked the "last pre-commercial version of Harvest" and renamed it to Squid to avoid confusion with the commercial fork called Cached 2.0, which became NetCache. Squid version 1.0.0 was released in July 1996. Squid is now developed almost exclusively through volunteer efforts. The above setup—caching the contents of an unlimited number of webservers for a limited number of clients—is the classical one. Squid can run on the following operating systems:
LiveJournal LiveJournal was started on April 15, 1999 by American programmer Brad Fitzpatrick as a way of keeping his high school friends updated on his activities. In January 2005, blogging software company Six Apart purchased Danga Interactive, the company that operated LiveJournal, from Fitzpatrick. Six Apart sold LiveJournal to Russian media company SUP Media in 2007, but continued to develop the site by the San Francisco-based company LiveJournal, Inc. In January 2009 LiveJournal laid off some employees and moved product development and design functions to Russia. Features The unit of social networking on LiveJournal is quaternary (with four possible states of connection between one user and another). Two users can have no relationship, they can list each other as friends mutually, or either can "friend" the other without reciprocation.
