Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over anetwork (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation.The origin of the term cloud computing is obscure, but it appears to derive from the practice of using drawings of stylized clouds to denote networks in diagrams of computing and communications systems. The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network on telephony schematics and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. The cloud symbol was used to represent the Internet as early as 1994.John McCarthy opined in the 1960s that "computation may someday be organized as a public utility." Almost all the modern-day characteristics of cloud computing the comparison to the electricity industry and the use of public, private, government, and community forms, were thoroughly explored in Douglas Parkhill's 1966 book, The Challenge of the Computer UtilityAfter the dot-com bubble, Amazon played a key role in the development of cloud computing by modernizing their data centers, which, like most computer networks, were using as little as 10% of their capacity at any one time, just to leave room for occasional spikes. Having found that the new cloud architecture resulted in significant internal efficiency improvements whereby small, fast-moving "two-pizza teams" (teams small enough to be fed with two pizzas) could add new features faster and more easily, Amazon initiated a new product development effort to provide cloud computing to external customers, and launched Amazon Web Service (AWS) on a utility computing basis in 2006.
November 30, 2011In computing, virtualization (or virtualisation) is the creation of a virtual (rather than actual) version of something, such as a hardware platform, operating system (OS), storage device, or network resources.While a physical computer in the classical sense is clearly a complete and actual machine, both subjectively (from the user's point of view) and objectively (from the hardware system administrator's point of view), a virtual machine is subjectively a complete machine (or very close), but objectively merely a set of files and running programs on an actual, physical machine (which the user need not necessarily be aware of).

Public cloudPublic cloud describes cloud computing in the traditional mainstream sense, whereby resources are dynamically provisioned to the general public on a fine-grained, self-service basis over the Internet, via web applications/web services, from an off-site third-party provider who bills on a fine-grained utility computing basis.Community cloudCommunity cloud shares infrastructure between several organizations from a specific community with common concerns (security, compliance, jurisdiction, etc.), whether managed internally or by a third-party and hosted internally or externally. The costs are spread over fewer users than a public cloud (but more than a private cloud), so only some of the benefits of cloud computing are realised.About Merit NetworkMerit Network, Inc. is a nonprofit, member-owned organization formed in 1966 to design and implement a computer network between public universities in Michigan. After 40 years of innovation, Merit continues to provide high-performance networking and services to the research and education communities in Michigan and beyond. 3]Private cloudPrivate cloud is infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted internally or externally.They have attracted criticism because users "still have to buy, build, and manage them" and thus do not benefit from lower up-front capital costs and less hands-on management,essentially "[lacking] the economic model that makes cloud computing such an intriguing concept".Nebula is an open-source cloud computing project and service developed to provide an alternative to the costly construction of additional data centers whenever NASA scientist or engineers require additional data processing. Nebula also provides a simplified avenue for NASA scientists and researchers to share large, complex data sets with external partners and the public.Hybrid cloudHybrid cloud is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together, offering the benefits of multiple deployment models
Sierra also will provide libraries with the option to run Sierra locally or via a "private cloud," differentiating Sierra from locally run Millennium. (As Sandy Hurd, director of strategic markets at III, notes in the comments below, III does offer system and application hosting for individual libraries and consortia.) In this aspect, Sierra will go head-to-head with other high-profile cloud-based library automation products announced by III competitors over the last several months, including OCLC's aforementioned Web-scale Management Services, due to roll out in June, and Ex Libris's AlmaThe OCLC WorldShare Platform is a global, interconnected Web architecture that supports OCLC's Webscale services and applications, and provides flexible, open access to library data through APIs and other Web services. Libraries, developers and partners can use this data to innovate together to build and share apps that streamline and enhance their local library workflows. The OCLC WorldShare Platform facilitates collaboration and app-sharing across the library community, so that libraries can combine OCLC-built applications, library-built applications and partner-built applications. This enables the benefits of each single solution to be shared broadly throughout the library community. Unlike traditional APIs and Web Services, the OCLC WorldShare Platform allows community members to browse and install apps directly into subscribed OCLC services and allows developers to create and share apps that don't require OCLC services at all.
Spotify is a cloud based service that allows people access to their 15 million song library, with the ability to develop playlists, share files as well as download mp3s. Now, no matter where people are, they can access their customized playlists on Spotify’s cloud and download or share this data with other Spotify users. The technological breakthrough is identified by Spotify’s seamless integration with user’s personal libraries and the ability to share files within your social network.
Waze is all about contributing to the 'common good' out there on the road.By connecting drivers to one another, we help people create local driving communities that work together to improve the quality of everyone's daily driving. That might mean helping them avoid the frustration of sitting in traffic, cluing them in to a police trap or shaving five minutes off of their regular commute by showing them new routes they never even knew about.So, how does it work?After typing in their destination address, users just drive with the app open on their phone to passively contribute traffic and other road data, but they can also take a more active role by sharing road reports on accidents, police traps, or any other hazards along the way, helping to give other users in the area a 'heads-up' about what's to come.In addition to the local communities of drivers using the app, Waze is also home to an active community of online map editors who ensure that the data in their areas is as up-to-date as possible
At its core, Evernote does one thing, and does that very well. It collects clips of data from the Web sites you're reading or the applications you're using, and gathers them into categories that can be synced in the cloud and accessed from multiple devices. I noticed Evernote had pervaded the apps repertoires of many of the Syracuse University students we covered during last month's MLB.com Apps Challenge. Now that laptops, tablets, and in some universities, thin client desktops are the principal research tool of every scholar, Evernote has quickly risen to the level of ubiquitousness among this specific class of users - as invaluable to the work they do as Twitter.
Because of its simplicity and intuitive design, Dropbox may perhaps be the most popular cloud storage service embraced by the web today. You can do a lot with Dropbox, including being able to share files with the public with a link and you can invite your friends on Facebook to share Dropbox files. Even with a free account, you can expand your 2 GB of free storage up to 18 GB of free storage by referring new people to join Dropbox. If you’re already paying for more storage, you can still increase it up to 32 GB with no further payment by referring new users.Free storage: 2 GB (Get more space through referrals.)
