The Cloud Of Cloud Computing

Cloud computing is a fast growing information technology trend that many companies including Google, Microsoft, and IBM are currently looking to get a stake in as demand for the service grows. Cloud computing is the concept of allowing both individuals and businesses to store data and applications on remote servers (owned and operated by a third party company), rather than on their own hard drives and data centers. The service boasts the ability to securely access data and applications from just about any device with an internet connection, allowing for such services as streaming music from a personal collection from multiple devices, and even to business

Cloud computing is the practice of using remote storage for applications and data. The idea itself is not a new one; it has been in use for many years albeit under different names. In the earliest days of the computer age machines had to be physically large to contain the hardware required to do their jobs. It was impractical and prohibitively expensive to provide one of these mainframes for individual users; not to mention for what they were used for, unnecessary. Instead, one central computer was wired to several terminals that users could interface with. Typically, only large organizations such as, major corporations or government agencies could afford one of these machines or had need of one. This was the birth of cloud computing. Until the early 1980s this system was typical for any organization requiring large amounts of processing power. It was considered unnecessary and difficult to put the nuts and bolts of applications onto users’ desktop machines. Rather, by keeping applications in a central location, they could be managed and updated more easily and large amounts of storage space and processing power were not needed on desktop machines. Indeed, before this time there were no desktop machines mass produced that could achieve this level of power. This was about to change.

Cloud Computing is the use of common software, functionality or business applications from a remote server that is accessed via the Internet. Basically, the Internet is the "cloud" of applications and services that are available for access by subscribers utilizing a modem from their computer. With Cloud Computing, one simply logs into desired computer applications - such as sales force or office automation programs, web services, data storage services, spam filtering, or even blog sites. Generally, access to such programs is by monthly or annual paid subscription. Through Cloud Computing, businesses may prevent financial waste, better track

Cloud computing have revolutionized life as we know it; it allows people to store, manage, and access their data by using a network of remote servers which are hosted on the internet rather than using a local server or own hardware. A recent study conducted by KPMG found that 81% of businesses were either evaluating cloud services, planned a cloud implementation or had already implemented a cloud strategy [1]. Organizations tend to use the cloud to reduce costs and improve efficiency. Cloud is not a commodity, some people think that it comes out of the sky, while in fact it comes from physical hardware inside brick and mortar facilities which are connected to hundreds of miles by networking cables.

SaaS is a cloud computing model where the service provider is responsible for managing the entire cloud infrastructure, platform and is also responsible for the secure deployment and management of the customer-required applications such as office suite applications - that is why SaaS is sometimes referred to as “finished services” (Squicciarini, et al., 2016).

Cloud computing comes in three distinct implementations or models, each with its own pros and cons. The advantage is that each can be tailored to meet a specific need. The three different implementations are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). In IaaS, an organization uses the cloud to provide virtual resources, such as storage space for data or online databases. Amazon’s Simple Storage Service (S3) is an example of IaaS, with customers utilizing the S3 cloud to store information. PaaS implementations run on top of IaaS, giving the organization flexibility to implement customized applications, such as specific portions of Google apps. Finally, SaaS is the transition to almost all operations to the cloud. In SaaS, a small blade system is used to connect to the cloud through an Internet connection where all the software and major computing power is stored. Instead of having an OS installed on each desktop system, the OS and everything else needed is stored on the cloud servers and accessed through a web browser or custom plug-in. (Neamtiu & Dumitras, 2011)

Software as a Service (SaaS), sometimes referred to as "on- demand software" is a software delivery model in which software and associated data are hosted on the cloud. SaaS is typically accessed via a web browser and is paid on a subscription basis, monthly or yearly as per requirement.

In order to fully understand what software as a service is and how it can benefit the user you must first have an understanding of how this type of computing is accomplished. I think it is important to understand what is meant by the “Cloud”. Cloud computing or software as a service, put simply is when software is ran over the Internet and accessed by an Internet browser (Schneier, 2009).

Software As A Service (SAAS): is also called as "on-demand software" [2] and defined as a software distribution service in which applications and their associated data are hosted by vendors or by the cloud service providers and made available to the cloud clients over a network, typically the internet [3].SAAS provides those clients with a complete operating environment with management, user interface and applications [4].

Cloud computing is the practice of using remote network servers via the Internet to manage, store and process data. Many businesses use cloud computing because in a lot of cases it can be cheaper, faster and easier to maintain then local servers. Since its introduction cloud computing has grown to not only be used by businesses but also regular Internet. Cloud computing services such as Google Docs, Dropbox and more are one of the reasons for this shift. They allow the user to access their files whenever and wherever they want.

The term cloud computing was first coined in 1996. However, the idea of sharing computing resources was conceived in the early 1970’s. Cloud refers to an agglomeration of objects, and it is used in cloud computing to refer to a set of things that are used together. In 1977, ARPANET used a cloudlike logo in referencing their network that had interconnected a variety of computer resources. A cluster of servers in the company’s premises looked like a cloud. Their server was circular, and the agglomeration of the servers ended up looking like a crowd. In 1981 CSNET another predecessor also used a cloud symbol for their computing components.

The cloud is a data storage method that stores information on the iInternet rather than in a secure facility. Cloud data revolutionized the way companies store their information by making it easier to organize files from any location —, not just the office desktop. Suddenly CEO’s could work from Bermuda, having access to every file on the go.

1.Cloud Computing: Cloud computing is defined as the different services such as service, storage and applications are deliver to organization devices and computers through internet. There are mainly three types of clouds they are private public and hybrid and three services are offered by the cloud mainly Software as a service in which user rent access to software application functionally over the internet eg:ltu student mails .,

Cloud computing is a topic of which much is assumed. The average person recognizes the term “cloud computing” as having to do with their storage from their iPad or iPhone on the online storage area which syncs their Apple devices to their computer. This common cloud is called the iCloud. That is where common knowledge ends about this topic. However, upon further exploration, a deeper understanding is gained with greater explanation, and it is realized that cloud computing is something that is used all of the time on many levels of everyday technology. While the terminology remains cryptic to the mind of most people, the concepts behind the practical uses of cloud computing become quite clear. It is relatable and understandable. Upon this revelation, the iCloud is recognized as the tip of the preverbal iceberg when speaking about cloud computing. It is important to discuss and further understand the many types of cloud computing as well as the various applications to life through technology. This affects how information is stored online, computers are protected, information is secured, emails are processed, and many other factors that are taken for granted in the world of technology. Cloud computing is a general term used to describe how information is stored, utilized, and accessed over the internet. There is no cloud, but the word cloud gives the connotation of an abstract place which is known to exist but is too vast to touch or contain (Griffith,

In essence, this technology came about when the culmination of Internet Service Providers (ISP) developed the ability to host web services and create a virtualized infrastructure (MSV, 2012, p. 5). A virtualized infrastructure – better known as virtualization – is where multiple servers are consolidated (MSV, 2012, p. 5). For instance, an organization can have individual servers for each of the following “roles like Web Servers, Database Servers and Messaging Servers” (MSV, 2012, p. 4). Instead of having a plethora of servers to handle these many different roles each server is virtualized to take on multiple roles here by “the data center infrastructure can be consolidated from hundreds of servers to just tens of servers” (MSV, 2012, p. 4). Initially this technology was implemented in data centers as a means for organizations to lower a data centers total cost of ownership; therefore, saving companies significant amounts of money on power bills, cooling equipment, and hardware in general (MSV, 2012, p. 5). Although today 's cloud technology is widely developing into a product called Software as a Service (SaaS) (Srinivasan, 2013, p.48). In example, services like iCloud, Google Drive, or OneDrive from Microsoft are considered SaaS (Srinivasan, 2013, p.49). These examples offer a certain amount of free storage space for users who employ their services and have an account which is usually free as well.
