In Computer science, cloud computing describes a type of outsourcing of computer services, similar to the way in which electricity supply is outsourced. Users can simply use it. They do not need to worry where the electricity is from, how it is made, or transported. Every month, they pay for what they consumed.

The idea behind cloud computing is similar: The user can simply use storage, computing power, or specially crafted development environments, without having to worry how these work internally. Cloud computing is usually Internet-based computing. The cloud is a metaphor for the Internet based on how the internet is described in computer network diagrams; which means it is an abstraction hiding the complex infrastructure of the internet.[1] It is a style of computing in which IT-related capabilities are provided as a service,[2] allowing users to access technology-enabled services from the Internet ("in the cloud")[3] without knowledge of, or control over the technologies behind these servers.[4]

According to a paper published by IEEE Internet Computing in 2008 "Cloud Computing is a paradigm in which information is permanently stored in servers on the Internet and cached temporarily on clients that include computers, laptops, handhelds, sensors, etc."[5]

Cloud computing is a general concept that utilizes software as a service (SaaS), such as Web 2.0 and other technology trends, all of which depend on the Internet for satisfying users' needs. For example, Google Apps provides common business applications online that are accessed from a web browser, while the software and data are stored on the Internet servers.

Cloud computing is often confused with other ideas:

Many cloud computing deployments are powered by grids, have autonomic characteristics and are billed like utilities, but cloud computing can be seen as a natural next step from the grid-utility model.[8] Some successful cloud architectures have little or no centralised infrastructure or billing systems including peer-to-peer networks like BitTorrent and Skype.[9]

The majority of cloud computing infrastructure currently consists of reliable services delivered through data centers that are built on computer and storage virtualization technologies. The services are accessible anywhere in the world, with The Cloud appearing as a single point of access for all the computing needs of consumers. Commercial offerings need to meet the quality of service requirements of customers and typically offer service level agreements.[10]Open standards and open source software are also critical to the growth of cloud computing.[11]

As customers generally do not own the infrastructure or know all details about it, mainly they are accessing or renting, so they can consume resources as a service, and may be paying for what they do not need, instead of what they actually do need to use. Many cloud computing providers use the utility computing model which is analogous to how traditional public utilities like electricity are consumed, while others are billed on a subscription basis. By sharing consumable and "intangible" computing power between multiple "tenants", utilization rates can be improved (as servers are not left idle) which can reduce costs significantly while increasing the speed of application development.

A side effect of this approach is that "computer capacity rises dramatically" as customers do not have to engineer for peak loads.[12] Adoption has been enabled by "increased high-speed bandwidth" which makes it possible to receive the same response times from centralized infrastructure at other sites.

Cloud computing is being driven by providers including Google, Amazon.com, and Yahoo! as well as traditional vendors including IBM, Intel,[13]Microsoft[14] and SAP.[15] It can adopted by all kinds of users, be they individuals or large enterprises. Most internet users are currently using cloud services, even if they do not realize it. Webmail for example is a cloud service, as are Facebook and Wikipedia and contact list synchronization and online data backups.

The Cloud[16] is a metaphor for the Internet,[17] or more generally components and services which are managed by others.[1]

The underlying concept dates back to 1960 when John McCarthy expressed his opinion that "computation may someday be organized as a public utility" and the term Cloud was already in commercial use in the early 1990s to refer to large ATM networks.[18] By the turn of the 21st century, cloud computing solutions had started to appear on the market,[19] though most of the focus at this time was on Software as a service.

Amazon.com played a key role in the development of cloud computing when upgrading their data centers after the dot-com bubble and providing access to their systems by way of Amazon Web Services in 2002 on a utility computing basis. They found the new cloud architecture resulted in significant internal efficiency improvements.[20]

2007 observed increased activity, including Google, IBM and a number of universities starting large scale cloud computing research project,[21] around the time the term started gaining popularity in the mainstream press. It was a hot topic by mid-2008 and numerous cloud computing events had been scheduled.[22]

In August 2008 Gartner observed that "organizations are switching from company-owned hardware and software assets to per-use service-based models" and that the "projected shift to cloud computing will result in dramatic growth in IT products in some areas and in significant reductions in other areas".[23]

Clouds cross many country borders and "may be the ultimate form of globalisation".[24] As such it is the subject of complex geopolitical issues, whereby providers must satisfy many legal restrictions in order to deliver service to a global market. This dates back to the early days of the Internet, where libertarian thinkers felt that "cyberspace was a distinct place calling for laws and legal institutions of its own"; author Neal Stephenson envisaged this as a tiny island data haven in his science-fiction classic novel Cryptonomicon.[24]

Although there have been efforts to match the legal environment (such as US-EU Safe Harbor), providers like Amazon Web Services usually deal with international markets (typically the United States and European Union) by deploying local infrastructure and allowing customers to select their countries.[25] However, there are still concerns about security and privacy for individual through various governmental levels, (for example the USA PATRIOT Act and use of national security letters and title II of the Electronic Communications Privacy Act, the Stored Communications Act).

In March 2007, Dell applied to trademark the term '"cloud computing" in the United States. It received a "Notice of Allowance" in July 2008 which was subsequently canceled on August 6, resulting in a formal rejection of the trademark application in less than a week later.

In November 2007, the Free Software Foundation released the Affero General Public License (abbreviated as Affero GPL and AGPL), a version of GPLv3 designed to close a perceived legal loophole associated with Free software designed to be run over a network, particularly software as a service. According to the AGPL license application service providers are required to release any changes they make to an AGPL open source code.

Cloud architecture[26] is the systems architecture of the software systems involved in the delivery of cloud computing (e.g. hardware, software) as designed by a cloud architect who typically works for a cloud integrator. It typically involves multiple cloud components communicating with each other over application programming interfaces (usually web services).[27]

This is very similar to the Unix philosophy of having multiple programs doing one thing well and working together over universal interfaces. Complexity is controlled and the resulting systems are more manageable than their monolithic counterparts.

Cloud architecture extends to the client where web browsers and/or software applications are used to access cloud applications.

Cloud storage architecture is loosely coupled where metadata operations are centralized enabling the data nodes to scale into the hundreds, each independently delivering data to applications or users.

A cloud application influences The Cloud model of software architecture, often eliminating the need to install and run the application on the customer's own computer, thus reducing software maintenance, ongoing operations, and support. For example:

A cloud client is computer hardware and/or computer software which relies on The Cloud for application delivery, or which is specifically designed for delivery of cloud services, and which is in either case essentially useless without a Cloud.[33] For example:

Cloud infrastructure (e.g. Infrastructure as a service) is the delivery of computer infrastructure (typically a platform virtualization environment) as a service.[41] For example:

A cloud platform (e.g. Platform as a service) (the delivery of a computing platform and/or solution stack as a service) [42] facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers.[43] For example:

A cloud service (e.g. Web Service) is "software system[s] designed to support interoperable machine-to-machine interaction over a network"[44] which may be accessed by other cloud computing components, software (e.g. Software plus services) or end users directly.[45] For example:

Cloud storage is the delivery of data storage as a service (including database-like services), often billed on a utility computing basis (e.g. per gigabyte per month).[46] For example:

Traditional storage vendors have recently begun to offer their own flavor of cloud storage, sometimes in conjunction with their existing software products (e.g. Symantec's Online Storage for Backup Exec). Others focus on providing a new kind of back-end storage optimally designed for delivering cloud storage (EMC's Atmos), categorically known as Cloud Optimized Storage.

A cloud computing provider or cloud computing service provider owns and operates cloud computing systems serve someone else. Usually this needs building and managing new data centers. Some organisations get some of the benefits of cloud computing by becoming "internal" cloud providers and servicing themselves, though they do not benefit from the same economies of scale and still have to engineer for peak loads. The barrier to entry is also significantly higher with capital expenditure required and billing and management creates some overhead. However, significant operational efficiency and quickness advantages can be achieved even by small organizations, and server consolidation and virtualization rollouts are already in progress.[47]Amazon.com was the first such provider, modernising its data centers which, like most computer networks were using as little as 10% of its capacity at any one time just to leave room for occasional spikes. This allowed small, fast-moving groups to add new features faster and easier, and they went on to open it up to outsiders as Amazon Web Services in 2002 on a utility computing basis.[20]

The companies listed in the Components section are providers.

A user is a consumer of cloud computing.[33] The privacy of users in cloud computing has become of increasing concern.[48][49] The rights of users is also an issue, which is being addressed via a community effort to create a bill of rights (currently in draft).[50][51]

A vendor sells products and services that facilitate the delivery, adoption and use of cloud computing.[52] For example:

A cloud standard is one of a number of existing (typically lightweight) open standards that have facilitated the growth of cloud computing, including:[57]

Cloud computing has fundamentally expanded the realm ofpossibilities organizationscan accomplish with technology.While a lot of focus has been placed on the cloud technology and dataarchitecture advancements, the underlying telecommunications infrastructure is also seeing a shift in strategies to support the latest trends in cloud computing.

Cisco Systems, Inc., known for its hardware infrastructure deployments, is helping drive this shift. Ian Wells(pictured, left), distinguished engineer, cloud and platform services at Cisco Systems Inc., and Jerome Tollet(pictured, right), distinguished engineer, Chief Technology and Architecture Office, at Cisco Systems, are twoof the companys team membersspearheading this initiative.

Wells and Tollet spoke with host Stu Miniman (@stu) and guest host John Troyer (@jtroyer), of theCUBE, SiliconANGLE Medias mobile live streaming studio, during OpenStack Summit in Boston, Massachusetts. They discussed theirtechnicalperspectives on virtualization and cloud computing.(*Disclosure below.)

Of all the advances in telecommunications infrastructure, the most important technology for advancing cloud computing is Network Function Virtualization, according to Tollet. NFV is becoming a first-class citizen for this community. At the beginning, people were kind of ignoring NFV, it was all about cloud. Now its becoming quite the opposite, he said.

NFV is the term used to describe the virtualization of functions that historically have been physical hardware used for things like intrusion detection and routing.As the adoption rate for NVF rises, so does the demand for more features, which can create bottle necks in development.

On the networking side, its always, Id like more functionality. Youll hear people talk about service chaining. MPLS [Multiprotocol Label Switching] comes up quite regularly, which is really integration with the rest of the service provider network, Wells said. We have a ways to go to really address the kind of general purpose model that would suit everyone.

Tollet also brought up a very interesting point about the redundancy and overheadassociatedwith a completely virtualized system.

Think in terms of two containers sitting on the same virtual compute node. Why do you need to create a packet? Why do you need to do crypto? Why do you need to do virtual LAN when the two applications are sitting on the same compute node? Tollet said.We have imported into the virtual world all of the concepts we have used in the physical world now I think we can do something a bit more efficient .

Cloud Computing ran second to J Boys Echo in the Grade 3 Gotham Stakes.

ELMONT, N.Y. Before Mother Nature poured buckets of water on Long Island on Saturday morning, trainer Chad Brown was able to get in Cloud Computings last major workout before next Saturdays 142nd Preakness Stakes at Pimlico.

With steady rain falling at Belmont Park shortly after 5:30 a.m. Saturday, Cloud Computing worked a half-mile in 48.56 seconds over the training track that would be considered fast. Working by himself, Cloud Computing went in splits of 12.43 seconds for the opening eighth, 24.47 for the quarter, and got his final quarter in 24.09 without too much encouragement from exercise rider Peter Roman. He galloped out five furlongs in 1:01.69.

The horse breezed well, Brown said. He went a good half, out five. I thought he did it real, real well. Hes moving sound and strong. Im real happy with this horse. If he comes out of it in good shape, well be on to Maryland.

Cloud Computing, a son of Macleans Music owned by Seth Klarman and William Lawrence, has a win from three starts. That victory came going six furlongs over Aqueducts inner track on Feb. 11. He wheeled back three weeks later in the Grade 3 Gotham and ran a respectable second behind J Boys Echo after chasing a fairly hot pace. Cloud Computing then had a wide trip when the inside part of Aqueducts main track was the preferred spot when he finished third behind Irish War Cry and Battalion Runner in the Grade 2 Wood Memorial.

Cloud Computing did earn enough points to run in the Kentucky Derby, but Brown and his owners felt it was too much too soon for the horse. Cloud Computing needed a chip removed from a front ankle last summer, which is why he didnt run at age 2.

I feel very comfortable that we gave him the six weeks from the Wood, Brown said. I see a horse thats really doing well.

Javier Castellano will ride Cloud Computing in the Preakness. Brown said he anticipates shipping Cloud Computing to Baltimore on Tuesday.

Term of Art works

At Santa Anita on Saturday morning, Term of Art, one of the outsiders in the Preakness, worked six furlongs in 1:13.80 while outfitted in blinkers, which trainer Doug O'Neill said he will wear in the second leg of the Triple Crown.

Term of Art has scored both of his wins in blinkers, but he has not worn them in his last three starts, including a seventh-place finish in his last start, the Santa Anita Derby.

On Saturday, with exercise rider Amir Cedeno up, Term of Art worked by himself.

"He worked great," O'Neill said. "The track was demanding safe but slow. I'm very happy. We know he's a longshot, but he's doing well."

O'Neill said Term of Art would fly to Baltimore from California on Tuesday. He will be the only horse O'Neill has at Pimlico next weekend.

O'Neill won the Preakness in 2012 with I'll Have Another, his first Kentucky Derby winner. Last year, he finished third in the Preakness with Derby winner Nyquist.

Always Dreaming, the Derby winner, has been at Pimlico since last Tuesday and on Saturday galloped 1 1/4 miles on a sloppy, sealed track. The wet track forced the postponement of a scheduled work for Royal Mo, who traveled with Always Dreaming to Pimlico on Tuesday. He could work Sunday or wait until Monday.

Gunnevera, seventh in the Derby, was scheduled to arrive at Pimlico on Saturday after a van ride from Churchill Downs.

Cloud Computing puts in work for Preakness before deluge - Daily Racing Form

The Depository Trust & Clearing Corporation (DTCC), which already hosts some applications in the cloud, said cloud computing has now "moved past a tipping point" whereby it offers greater benefits and fewer risks to traditional outsourcing arrangements.

Financial services and technology law expert Luke Scanlon of Pinsent Masons described DTCC's move as a sign that the barriers that dissuade many financial firms from utilising cloud-based solutions are diminishing.

"The DTCC, after a period of testing and detailed analysis, have here highlighted that some of the traditional reasoning as to why cloud services present significant risk such as concerns around security are no longer valid," Scanlon said.

"In 2017 we are certainly seeing a maturing of the discussion and more and more of a focus on the few remaining regulatory sticking points to cloud adoption, together with the practical concerns around achieving the levels of availability necessary to operate the core systems of financial institutions and utilities, liability and exit arrangements," he said.

In a new white paper it has published, which contained its strategy to leverage the cloud, the DTCC explained why it will move more of its applications and services into the cloud.

"DTCC has been leveraging cloud services for almost five years and believes the cloud represents a viable alternative to corporate data centres," it said. "The maturation, expanded offerings and enormous scale of the technology, resolve the privacy and security challenges of cyber-threats, potential flash crash type market disruptions and the cost challenges facing many financial firms today."

"DTCC believes cloud computing has moved past a tipping point, prompting the firm to pursue a strategy of building a cloud ecosystem with partner vendors that support best practices and standards. DTCC is taking this step because it is confident that the security, scalability, resiliency, recoverability and cost of applications in the cloud are better than almost any private enterprise could achieve on its own," it said.

"DTCC also believes that business services, delivered by applications written to take advantage of the infinite resources, resiliency, and global reach of the cloud, have a significant advantage over legacy applications using traditional models in private data centres. We believe that gap will continue to widen over time," the firm said.

DTCC said it plans to work with regulators to ensure that its cloud-based operations are compliant with "the highest and strictest levels of recommended controls and best practices" it is subject to.

Earlier this year,seven main hurdles to banks' adoption of cloud-based serviceswere highlighted in a joint report by Pinsent Masons and UK banking industry body the BBA.

The district is also developing a single sign-on platform to better integrate applications and data.

With nearly 60,000 students and a mix of traditional, charter and pilot schools, CIO Mark Racine is always looking for ways to make educational technology go farther for the faculty and families of Boston Public Schools.

Like many CIOs, Racine has his eye on cloud computing as the future of data management.

But with limited funding preventing an immediate full-on move to the cloud, Racine and his infrastructure team are still banking on a hybrid approach, he said in a recent interview with EdScoop. The approach provides scaling opportunities to relieve stress on the network, especially at certain high-traffic points during the school year.

He likened it to the 1-800-Flowers approach, the way flower companies will need to scale up for Valentine's Day, and then come back inside, Racine said.

We would move to the cloud tomorrow if we could, he said.

View more of EdScoop's interviews with innovative school CIOs.

Among other edtech initiatives, Racine said he and his 50-member IT team have also invested heavily in single sign-on technology, geared towards increasing connectivity across the district.

The technology is also aimed at building toward greater data integration. The platform will take authentication to all kinds of different learning apps, and allow us to take our Ed-Fi database and scale that data to all educational platforms as well, he said.

When an educational technology platform is working well in a classroom or school, we want to be able to bring that up to 130 buildings, he said.

Another big initiative underway for Boston Public Schools, according to Racine, is finding the best way to support the districts school choice program.

Boston schools offer parents the flexibility to walk into a family resource center, explore all the schools that are available to them, learn about the educational programming that's in that building, and then be able to make a choice on where they want to send their child.

The ultimate goal of this is to, as Racine says, Eliminate the amount of lost-learning time, through the process of integrating technology into school choice programs.
