Cloud Computing And The Cloud Essay

The cloud can provide swift access to malleable and low budget IT resources. With the use of cloud computing, you are not required to make big direct investments in hardware and spend a lot of time on managing that hardware and associated services. Cloud Computing compromises a comprehensive set of on-demand services, such as global computing, storage, database, analytics, application, and deployment services. These services will assist an organization move quicker, reduce IT costs, and scale systems. Cloud Computing has three key categories, they are usually referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Mobile as a Service (MaaS) and Software as a Service (SaaS).

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]:

With the unprecedented growth and spread of information, there is no wonder why large Information Technology companies have been investing in the “cloud”. To expand, when referring to Cloud Computing, this means to access and store information not stored with in your computer whether it be public, private, or hybrid cloud computing. In technological terms, the server you are accessing is somewhere else and therefore, the information and tools you are using are “up in the clouds” but more so stored in another server space. However, whether you are paying for

According to the definition of the U.S. National Institute of Standards and Technology (NIST, 2011), “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 collected of five essential characteristics, three service models, and four deployment models. Moreover,

There are different types of cloud computing services available on the market which falls into one of the following categories.

Cloud computing is becoming very popular amongst private users as well as business sectors due to its benefits of availability, time saving and cheaper. However, one of the biggest factors which hold back the users is Security and Reliability of the data. The report briefly describes cloud computing, its characteristics, and its three major categories. It discusses about the reliability of data in cloud computing. The report also discusses about the NoSQL database of the Cloud Service Provider giants like Google, Amazon, and Apache and how they ensure reliability of the data in their services. Finally, the report discusses about the data security in the cloud computing infrastructure. It throws light on the security of data at various levels like Network Transport Security, Data Storage Security, and Data Management Security.

Cloud computing is Internet-based computing, whereby shared information, resources, and software, are provided to terminals and portable devices on-demand. It is a rapidly developing and excellent promising technology. Cloud computing is the product of the combination of grid computing, distributed computing, parallel computing, and ubiquitous computing. Cloud Computing model has enabled IT organizations to serve the users globally. It gives the services like Platform as a Service, Software as a Service and Infrastructure as a Service without users being much aware of the details in which the services are provided.

The largest Buzzword in emerging trends for the computer world is “Cloud”. Cloud computing in the future for data, services and platform. The concept of cloud computing is to make whatever aspect it is being used in available at all times and to act as a resource. Turning computing into a utility will transform how the IT industry uses services, designs hardware and uses network infrastructures. The term “Cloud” however has many meanings, but understanding what exactly is meant by cloud computing is the first step to

c)Commodified: The result is a utility computing model similar to traditional that of traditional utilities, like gas and electricity - you pay for what you would want. In many ways the cloud computing is simply a metaphor for the internet, the increasing movement to compute and data resources onto the web. But there’s a difference :cloud computing represents a new tipping point for the value of the network computing. It delivers higher efficiency, massive scalability and faster, easier software development.

Technology continuously attempts to re-invent and re-define itself nowadays. It is developing at a very fast pace globally, and is taking over the way people live their lives every day. When you think back to what computers use to be when they were first invented, to what they are now, it really is remarkable. When I think back to my first computer, key words/phrases that jump out to me are: AOL, dial-up, big bulky computers, long loading times. Those days are long gone now with consistent new software and technology updates. Almost every household owns a computer or a device that can gain internet access. In addition, there are also many locations that offer free WI-FI access to connect. This era has become so technology driven. This is

The use of cloud technology has become increasingly mainstream as individuals and businesses adapt to an environment in which having access to information and services 24/7, on a computer, phone or tablet is normal the new norm. Convenience, efficiency and data protection

Cloud computing is a practical model that has significantly reduced cost and increased benefits as well as having the potential to transform a data center from a capital intensive setup to a variable priced environment. Reusability of IT capabilities is the fundamental core principle where unlike the grid computing, cloud computing has to widen its horizons across organizational boundaries. Organizations are not required to install a piece of software on their local computing devices such as laptops or personal desktops but access this application from the internet such as webmail, web conferencing and much more. How cloud computing wins over platform dependency in addition to making business applications flexible, mobile, and collaborative.

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[NIST].

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.

People have a tendency to talk about cloud computing as if everyone understands exactly what this means. If you have never had it explained, it is possible that you may not have any idea about what it is. To
