The Cloud Of Cloud Computing

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

Cloud Computing is considered the latest buzzword in computing today. It describes a form of computing wherein services are accessed through the Internet on an as needed or pay-per-use basis. Some aspect of cloud computing is in use on a regular basis. Understanding this technology, its benefits, and underlying security risks are important for people in most of today’s technical areas. Because Cloud computing is still considered to be in its infancy, an introduction to cloud computing, defining its major components, with a focus on Software-as-a-Service (SaaS), is the foremost theme of this paper. There are three major elements of cloud computing - Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and

This report will be exploring what cloud computing is, the usages of cloud computing, a comparison of organisations that offer cloud services and their architectures, an explanation on how a typical software company may benefit from having a cloud implementation, a description of a challenge that cloud computing has in research and a description of a challenge in a commercial adaptation in connection to cloud computing.

Cloud computing comes up with designers and IT arrangements. capability to concentrate on factors such as providence, attainment and sufficiency planning. Due to increase in complications and costs of management, IT organizations found different models of cloud computing which respond to different needs of various users. National institute of standards and technology (2011) has described that cloud computing has three service models known as software as service(SAAS), Platform as a service (PAAS) and Infrastructure as a service(IAAS).cloud computing provides

Platform as a Service (PaaS) provides a platform and environment to allow developers to build applications and services over the internet (Interoute, n.d). Combined with Infrastructure as a Service (IaaS), developers can scale or modify resources in a short amount of time to make development easier, for example by increasing the number of servers available for testing. This later becomes useful when the solution is deployed, as the resources can be scaled up or down depending on how successful the development is.

The PaaS model is particularly oriented towards developers, who need to run their applications without having the need to configure an entire network architecture of VMs and manage multiple application updates and upgrades. This delivery model allows developers to manage only their code and the data structures, everything else (runtime, OS, VMs, VMMs, networks,...) is then managed by the cloud provider.

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,

Cloud computing is revolutionizing every aspect of Information Technology. Many businesses and organizations rely on their own internal IT departments to operate their specific applications, databases, and programs. Cloud allows them to cut ties with in-house servers and receive their complete IT needs from an external Cloud provider. Cloud is faster and easier to use than traditional infrastructures, often making it more cost effective. Several private companies have already switched to Cloud and the federal government has ordered every agency to identify at least three “must move” services and shift them to Cloud by mid 2012. (Scharff, 2011)

Because the cloud service providers have economies of scales by providing services to many clients, the cost that is realized from using these service providers can’t be beaten in terms of expertise and costs. Now, smaller entities can concentrate on their core competences instead of worrying about the infrastructures surrounding it.

Since the innovation of the internet, people in computing fields have seek to find storage solutions that could provide users and organizations with capabilities to store and process their data distant from end-uses. Since 2000s, cloud computing has come into existence, later on, became business feasible through the observation that organizations start to substitute from self-owned hardware and software to subscription mode based models. Thus, we’re currently on the shift to cloud computing that may cause a dramatic growth in internet-based IT services in some industrial areas and some decline in other areas. By definition, cloud computing is an internet based computing for storing or sharing used computer or applications on multiple servers.

Cloud computing paved the way to the specific type of service known as Software as a Service (SaaS) in the 1990s, as well as programs like Salesforce, which gave businesses the ability to have better “customer relationship management” (Goodrich 2013). As more SaaS programs became available, it was clear that agencies like The National Institute of Standards and Technology and Legal Cloud

provides an application or development platform in which Cloud customers can create their own application. More precisely, they provide a set of API that can be used by developers to program or compose applications for the Cloud.

acquiring and managing the underpinning hardware and software, which they then rent out to the users. With IaaS, users can get the same processing power and speed, as well as have access to unlimited storage space. In addition, the cloud as service provides platform as a

The technology used in Cloud Computing is often centralized on demand and can be offered in terms of services. Just like most internet service providers, the cloud services provide platforms for their clients to create web services (applications) on the internet. These applications are accessed through the web opposed to running off your local hard drive. Cloud computing enables its users to conveniently use various resources like storage, servers, and applications that can be launched with minimal effort. In common terms, cloud computing proposes three types of services: 1) SaaS: Software as a service, 2) PaaS: Platform as a service, and 3) IaaS: Infrastructure as a service. Cloud

“Cloud computing is a model for enabling ubiquitous, 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 is composed of five essential characteristics, three service models, and four deployment models.”
