1. Cloud Computing
Cloud computing is becoming one of the key words of the IT industry. The cloud is a metaphor for the Internet or infrastructure of communication between the architectural components, based on an abstraction that hides the complexity of infrastructure. Each part of this infrastructure is provided as a service and they are normally allocated in data centres, using hardware shared computing and storage (Buyya et al. 2009b). To use the service, users need only take their machines operating system, browser and Internet access. All computing resources are available on the Internet. Therefore, the user’s machinery does not need to have high computational resources, as a result reducing the cost in the acquisition of machinery. All hardware can be used to perform a task that is appropriate to its processing power. New hardware features can be added to increase processing power and work with existing resources.
The cloud computing model was developed with the goal of providing accessible and affordable services, to ensure characteristics such as availability and scalability. This model aims to provide essentially three benefits. The first benefit is to reduce the acquisition cost and composition of the entire infrastructure required to meet the needs of business, this infrastructure can be composed on demand with varied resources and less costly. The second is the flexibility that this model offers regarding the addition and exchange of computational resources, for this reason being able to climb at both the hardware and software resources to meet the needs of businesses and users. The final benefit is providing an abstraction and ease of access to users of these services. In this sense, service users do not need t...

Today, cloud services are widely used by people around the world in purpose of business, government, and personal use. With cloud services, users use resources - could be storage, computional capability, or software- from cloud service provider mediated by Internet. Doing computational work with cloud services involves a number of computers to do the large-scale works, therefore it usually called by distributed system over Internet (reference, paper?). Cloud service also offers a large-scale service where users only pay for what they use (on-demand). Therefore, companies migrate to business-to-business cloud as they don’t have to spend money building intial cost for their computational business. For instance, instead of building their own storage, network, cooling, they could just “rent” resource from cloud provider for the lower cost. Besides money benefits, cloud resources also able to be shared by multiple...
Cloud computing is a model for enabling convenient, on demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.
To understand how cloud computing can be of value to an organization, it is important to us that we understand the cloud and its components. There are three different types of cloud computing services referred to as Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). IaaS delivers cloud computing infrastructure servers, storage, network and operating systems as an on-demand service. SaaS is about software deploying over the Internet. PaaS allows a creation of web applications without the complexity of buying and maintaining the software and infrastructure. In this paper, I will suggest that Innovartus Technology Inc should use IaaS as a replacement for PaaS because IaaS is a rapidly developing field with resources such as better services, cost variability, utility pricing model and dynamic scaling.

Cloud is the result of a decade research in the field of distributing computing , utility computing, virtualization , grid computing and more recently software, network services and web technology which is changeable evolution on demanding technology and services also as looking to the rapid growth of cloud computing which have changed the global computing infrastructure as well as the concept of computing resources toward cloud infrastructure. The important and interest of cloud computing increasing day by day and this technology receives more and more attention in the world (Jain, 2014) the mostly widely used definition of cloud computing is introduced by NIST “as a model for enabling a convenient on demand network access
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. A cloud is a combination of hardware, networks, storage, services, and interfaces that helps in delivering computing as a service. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. In addition, the platform provides on demand services to the users for accessing that are always on anywhere, anytime and any place. Cloud computing platform provides the scalability, availability and utility computing for services on Internet.
Cloud computing services provide a multitude of benefits for businesses of every size. Cloud computing services offer “flexible computing power and data storage, as well as data management, messaging, payment and other services that can be used together or individually (Laudon 2014). The list of benefits is long and varied. Cloud computing services are universal. Anyone and everyone can use the system. Cloud computing is cost effective. There is no maintenance fee, but rather a business pays for what they use. The amount of storage space is unlimited. This is a boon to companies who cannot accurately predict data usage. The ability to access private and public clouds ensures stability and security.
Cloud computing is a new dimension information technology (IT) and paradigm, which main aims to provide cost effective, reliable, customized and well guaranteed dynamic computing environment on “Pay-per-use” basis for the clients or end users....
The origins of cloud computing dates back to the 1960s around the time computers were introduced. It was unknown specifically what cloud computing was until 1997 where Ramnath Chellappa, information systems professor, used the term “cloud computing” and placed a definition behind it (Cantu, 2011). After the introduction of what cloud computing does companies began switching to using these services to benefit their own company. Statistically, “in 2009, revenue for cloud services was just over 58.6 billion” (Cantu, 2011). The growth of cloud services is capturing more of the market where in 2011 cloud computing accounting is opening up on the global market at 2.3% with plenty of room to grow (Cantu, 2011).
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.
Cloud computing remains firm and has great potential for the future despite its disadvantages and the fact that it is still is a working progress. The number of users are constantly growing and bigger companies are starting to be interested, offering better and finer tuned services and solutions. The best thing to do is to hope that the advantages will further grow and flourish and the disadvantages will slowly disappear, since cloud computing seems to have made IT a little bit easier (Morris, 2011).
During the past years a new solution appeared in the IT field, Cloud computing, and it is Impossible to overlook it, in light of the fact that Cloud computing permits organizations to outsource information, electronically mail, folders and different applications through virtual stages through the medium of servers
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.
Cloud computing is a model for delivering data resources to cloud end users, in which data resources are stored in distributed manner, data resources can be accessed on the internet using web-based tools and applications. Data and software packages are stored in server database. However, cloud server allows the cloud users to access data resources as long as system is connected to the internet.
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
