Cloud computing is here and basically every business, corporation, or organization is using it in some form. Learning and understanding the opportunities and risks that is interlinked with this technology can be very important. Cloud computing is a model for allowing convenient, on-demand network access to a shared collection of configurable computing resources. These resources included networks, storage, applications, servers, and services. It can be quickly provisioned and distributed with insignificant effort or interaction of service provider. Characteristics of cloud computing include rapid elasticity, broad network access, on demand self-service, measured service, and resource pooling.
The cloud model is consists of service models and deployment models. The cloud is comprise of three service model; Software as a Service (SaaS), which is capable of providing applications running on a cloud infrastructure, Platform as a Service (PaaS), which allows to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using tools supported by the provider, and Infrastructure as a Service (IaaS), which is capable of providing provision storage, networks, processing, and other computing resources. The cloud is contains four deployment model; private cloud, exclusively use by a single organization or multiple consumers, community cloud, exclusively used by a specific community of consumers with shared concerns, public cloud, provisioned for open use by the general public, and hybrid cloud, composited of two or more distinct infrastructures.

The Cloud is the inclusive term for a virtualized information technology computing environment, it began in the 1950s and has evolved itself into every organization. Cloud computing is very effect with individuals and businesses work, whether it be for data maintained or stored. The web-based environment make it more effective, rather than physically located in a user’s location. Whether it be infrastructure as a service, platform as a service, or software as a service, the cloud does have its benefits, just as well as its risks. Educating and understanding the possibilities and threats that comes with the power of this technology is important. Cloud computing is a representation convenient, on-demand network access to a shared computing resources. The possibilities are endless!
The second cloud infrastructure that I would like to describe is the Software as a Service model, which is also known as SaaS. The SaaS model provides a broad scope of devices that are able to access software programs from one company’s applications. System as a service was developed to run applications from any device or user that has permission from the host. The book states, “Online email services, such as Gmail and Yahoo!, are good examples of SaaS” (Jill West, 2016). Cengage Learning made the Software as a
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is

The article introduced the definition of cloud computing as both the applications delivered as services over the Internet and the data centers that provide those services. The article also compared the cloud computing with conventional data storage in many aspects. The author concluded that cloud computing is superior because it simplified operation and increased utilization via resource virtualization.
The academic community has also shown interest in cloud computing, and some work has been directed to improvements in aspects of performance, security, usability, implementation and reliability of the system as a whole (Armbrust et al. 2009). Other work has developed new techniques to make adequate infrastructure to each context of cloud computing environments, among which we highlight the project Eucalyptus (Liu et al. 2007), developed by the University of California. The following are some technology, such a model of programming, infrastructure and platforms for cloud computing.
Several types of cloud storage systems have been developed to supporting both personal and business uses. Cloud storage also a model of networked enterprise storage where the data is stored not only in the user's computer, but also in virtualized of storage, which generally hosted by third parties company.
When they wanted to save photos online instead of on your personal computer, they are able to use “cloud computing” service. Cloud computing means that the transfer of computing data or information over the internet. Not just to keep data in your personal computer, they are able to save the data on internet server to open their data in any computer. In this report we will walk through about what is cloud computing, what kinds of model did cloud computing have, types of cloud computing, benefits of cloud computing, and security.
One might ask how does cloud computing work? Cloud computing architecture refers to the components that work together to form cloud computing. The architecture behind cloud computing involves two different parts, the front end and the back end. Each part connects through the internet and works together. The front end structure is also referred to as the clients. This is the part or side of the server that the user interacts with and sees. For the user to connect and interact with this end, they need to have access to a computer with internet. An example of the front end structure being used is a user logging on the internet to check their email. Again, millions of people check their email every day and do not realize it is part of cloud computing. The other part of cloud computing architecture is called the back end structure. This part is responsible for the service that make the cloud work. It comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc. () The back end service is made up of Software as a Service (SaaS), Platf...
The purpose of this report is to study the current state of supercomputers and to briefly discuss predicted advancements in the field..A brief history about the supercomputer and its operation is initially outlined.
A cloud service is any resource that is provided over the internet. Service delivery in cloud computing comprises three different service models.
In 500 B.C. the abacus was first used by the Babylonians as an aid to simple arithmetic. In 1623 Wihelm Schickard (1592 - 1635) invented a "Calculating Clock". This mechanical machine could add and subtract up to 6 digit numbers, and warned of an overflow by ringing a bell. J. H. Mueller comes up with the idea of the "difference engine", in 1786. This calculator could tabulate values of a polynomial. Muellers attempt to raise funds fails and the project was forgotten. Scheutz and his son Edward produced a 3rd order difference engine with a printer in 1843 and their government agreed to fund their next project.
In order to fully understand the history of computers and computers in general, it is important to understand what it is exactly that lead up to the invention of the computer. After all, there was a time when the use of laptops, P.C.s, and other machines was unthinkable. Way back in the fourth century B.C., the abucus was an instrument used for counting in Babylonia. Many scholars believe that it likely started out as pebbles being moved over lines drawn in the dirt and then evolved into a more complex counting tool (Aspray 7). About 1200 years later, Roman numerals were finally introduced, along with the idea of the zero and other mathematical basics. This helped lay the foundation for several different men who had findings that would eventually lead us to the beginnings of computers and computing. Though they are often referred to as scholars, many of these intellectuals were most likely just merely the nerds of their time. Take Wilhelm Schickard and Blaise Pascal of the 17th century, for example. Both of these men had enough time on their hands to individually build two of the first mechanical calculators in history. Unfortunately, Schickard calculator never even made it past the model stage and Pascal machine had several snags of its own; nevertheless, both of their discoveries helped lead to more advanced computing. The next so-called geek to make his way into the computing spotlight was Charles Babbage. In 1842, he developed ideas for a computer that could find the solution to a math problem. His system was rudimentary, using punch-cards in the computation; however, his ideas were far from basic. In fact, the analysis of his Analytical Engine includes fundamentals of computer programming, including data analysis, looping, and memory addressing (History).
Thousands of years ago calculations were done using people’s fingers and pebbles that were found just lying around. Technology has transformed so much that today the most complicated computations are done within seconds. Human dependency on computers is increasing everyday. Just think how hard it would be to live a week without a computer. We owe the advancements of computers and other such electronic devices to the intelligence of men of the past.
The History of Computers In 1964, no one, with the exception of those within the field of study, had ever heard of a computer. Now, only forty years later, almost every home in America is equipped with at least one computer. A computer is defined as a device that accepts information, in the form of digital data, and manipulates it for some result based on a program on how data is to be processed. The first computer was not as fast or efficient as the computers used today, however they are all based on the first model.
Computer has been an important gadget in many peoples life. Computers come in various design, size and types. For example, there are computers that needs to be placed on the desk or on a flat surface like the desktop computer and the laptops. Where else we have the computers that can be carried along with us like the mobile phones and tablets. Computers are so important that it is used to communicate by billions of people. For example people use computer for far distance communication like sending emails to friend and workmates or talking to family members at any time without restriction and this is really convenient. Computers are also used for working purpose like the consumer using it for business, employees to employers as well as customers. (Gary B.Shelly 2011). Computers are also used for education in schools, library, and at homes as well by students, adults and kids. Computer is a very helpful medium to learn knowledge and information. In this 21st century, nothing works without the basic knowledge in computer for example a small shop uses computer to keep the records of thing that they have sold and even a road site food stall uses the calculator which is also a computer to count the price. Compare to the past era children used to play out door games but in recent era children prefer to play indoor with their computers. Today I will be writing about the modern history of computing since it is really important to know the history of computer.
