This report revolves around the topic of Cloud computing, Cloud computing software to be exact. For the purpose of this report information was gathered from various sources including electronic data, books, online journals and the World Wide Web. The topic of cloud computing software consists of an introduction which gives a brief history about the cloud, as well as the definitions of some key terms responsible for the growth of cloud computing as we know it today. It then goes on to define and discuss the types of cloud deployment methods also known as the different ways of approaching the cloud. They are the public, community, private and hybrid cloud. The next section then again defines and discusses the three main cloud delivery models which are the Platform-as-a-service, Infrastructure-as-a-service and software-as-a-service. A brief conclusion will be delivered at the end of the report to summarise main points discussed.
2. Introduction
"Like or loathe it, cloud computing is already starting to have a significant impact on the personal and corporate it computing landscape. Within a decade it is also likely to be the only computing show in town. None of us can therefore ignore cloud computing. Our only real choice is whether we want to be part of the steamroller or part of the road". (Barnatt, 2010,p.xii)
The idea behind cloud computing was originated from the early concepts of utility computing as far back as the 1950's. Utility computing here refers to a pay-per -use billing system where by computing services are provided (Janssen, n.d.)They are also called metered services. The name of utility computing was born out of utility companies like gas, electricity and telephone which also have a pay-as-you-go system. Cloud com...

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
Virtualization is a technology that creates an abstract version of a complete operating environment including a processor, memory, storage, network links, and a display entirely in software. Because the resulting runtime environment is completely software based, the software produces what’s called a virtual computer or a virtual machine (M.O., 2012). To simplify, virtualization is the process of running multiple virtual machines on a single physical machine. The virtual machines share the resources of one physical computer, and each virtual machine is its own environment.
Cloud computing is defined by experts as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The meaning behind the word cloud is that it is a metaphor for the entire online web and its data as well. A cloud service differs from traditional hosting in three different ways. These three differences are that cloud computing is elastic, it is sold on demand, and the service is managed by the provider of the cloud. The easiest way to explain what cloud computing does is that it stores and gives access to different data and programs over the internet rather than just your computer’s hard drive. For it to be actually considered cloud computing it must include data or programs over the internet. Cloud computing can be done anytime, anywhere with an online connection.
...Currently, there are no other alternatives, but since the emergence of cloud computing it has already started evolving. CIO’s Florentine suspects that cloud computing will be more software based rather than hardware based in the years to come.(Florentine, & Olavsrud, 2013).
Cloud computing is computing in which large groups of remote servers are networked to allow the centralized data storage, and online access to computer services or resources. Clouds can be classified as public, private or hybrid
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 computing is the transfer of computing data or information into Internet. Cloud computing services allows individuals and businesses to
The cloud computing is the practice that enables access to the shared pool of configurable computing resources which can be dynamically provisioned. It refers to both the applications delivered as service as well as hardware and system software in the data centres that provide those services. The attractive features of cloud computing such as on-demand access, high scalability, reliability, cost savings, low maintenance and energy efficiency bring benefits to both cloud service consumers and providers.
The cloud model comprises five essential characteristics are on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured services. It also offers main three service models such as software as a service (SaaS),platform as a service (PaaS), and infrastructure as a service (IaaS )and four deployment models are public, private, community, or hybrid. The cloud architecture must illustrate the platform and software compon...
The term “Cloud” is very popular among entrepreneurs and marketers, but it simply means the wonders of Internet. Cloud computing shares the same concept as utility computing, in which all the computers are connected through a network and shared computing resources, such as computation, storage and services, over the network. Typically, there are three major models of cloud computing services on the market, which are software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS).

Experts have claimed that the services provided by cloud computing help the companies who subscribe for its use to focus on things that would differentiate them from other in this way they don’t look for its infrastructure cost or the infrastructure of the business. Advocates likewise guarantee that this system permits undertakings to get their applications up and running
In simple terms, it's just a storage located remotely which you can access anywhere. It's like storing your files online and accessing it anywhere while using your laptop, mobile device or another PC.
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.
