Cloud Computing Case Study

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).

Today is the world of IOT (Internet of things) and so that data is producing at very high rate in the form of Big data. That is why it becomes very difficult for companies and organizations to invest too much upfront cost for the setup of infrastructure and platform to handle this big amount of data. Cloud computing has come in boom around the year 2007 with rapidly growing innovative social and business organizations. Cloud computing allows its users to use the on-demand resources from shared pool of configurable resources at a very nominal price.

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]:

Infrastructure as a Service(IaaS) is a technique for passing on Cloud Computing establishment servers, storing, mastermind and working systems as an on asking for advantage. Instead of getting servers, programming, datacenter space or framework adapt, clients rather buy those advantages as a totally outsourced advantage on ask.

Cloud computing can also be separated into three broad categories of service: software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). SaaS are applications that are typically run on remote computers that are owned and operated by a third-party; they connect to customers computers via the Internet. Examples would be, accounting software such as QuickBook on the enterprise side and services like Facebook or Google on the consumer side. The second category, PaaS is a platform for developers to design and build their own applications rather than use existing ones. These applications could range from a web site to a custom operating system. An example of a PaaS provider is Windows Azure Cloud Services. The third and final type of cloud offering is IaaS. IaaS is the actual nuts and bolts of computing hardware in virtual form. An IaaS provider such as Amazon Web Services (AWS) can offer their customers access to server farms that otherwise would be beyond their capability to operate.(Juve et al, 2013) Cloud computing, as it has come to be understood, is more than simply storing data remotely. It is instead, the idea of the technology itself

Cloud Computing is a wide term that defines an extended kind of services. In order to actually comprehend how the Cloud can be of worth to an association, it is the first significant to understand what the Cloud truly is and its diverse mechanisms. The different categories of Cloud Computing services normally mentioned to as

An example of an organization with a SaaS business model would be Facebook or LinkedIn; each offer access to software as a web-based interface. Platform as a Service is a computing platform being utilized as a service, which means that the platform is outsourced instead of an organization handling their own software or hardware features. An example of a PaaS business would be Windows Azure or Google App Engine, where applications or software can be created and distributed via one website. Infrastructure as a Service is where an organization completely outsources the management of their servers for data holding and is usually just billed for their usage. An example of a IaaS business would be RackSpace or GoGrid who concentrates primarily on storing the data on their services, allowing the cost efficient Cloud services that we enjoy.

Infrastructure as a Service (IaaS): This is the bottom layer of the model that offers the storage capacity and resources to customers, developers and IT organizations the opportunity to rent both physical devices and Rackspace through a Dedicated Hosting agreement or virtual computing power through a Cloud Hosting agreement. This allows many corporate IT systems to relocate from existing dedicated data centers into multiple sites providing performance with attractive pricing models.

By 2020, Forbes (McKendrick, 2012) has estimated that the cloud market will be worth $270 billion; this suggests that the market is expanding rapidly and users are becoming more aware of this feature. Many people, though, still ponder over the exact purpose of cloud computing: Cloud computing is a group of offline servers that are networked together to allow data to be stored centrally. For example, Drop box is an established cloud storage company that allows users to store documents, images and videos on their servers. This type of cloud computing is known as ‘Software-as-a-Service’, which are business applications that are hosted by the provider and delivered as a service (Hurwitz, 2010). Hurwitz also mentions two other types of cloud computing: ‘Platform as a Service (PaaS)’ and ‘Infrastructure as a Service (IaaS)’. ‘Platform as a service’ is where the consumer will create an application, using tools and software from the provider, then the provider will administer the consumer with networks, storage and servers. ‘Infrastructure’ as a service is where the provider will provide the consumer with physical computer or virtual machine.

At a minimum, IaaS public cloud services offer storage and compute services on a pay-per-use model. But the full array of public cloud providers services offered by all major is mind blowing. Virtual private networks, Highly scalable databases, big data analytics, machine learning , developer tools, application monitoring etc. Amazon Web Services was the first IaaS provider, followed by Microsoft Azure, Google Cloud Platform and IBM Cloud.

“IaaS essentially refers to purchasing the basic storage, processing power and networking to support the delivery of cloud computing applications. It's a logical next step for organizations that want to move specific processes and applications into the cloud, but that still want to maintain a large degree of control and administration over the functions and applications themselves” (Akamai Technologies ).

The information technology industry is growing at a rapid pace. Every business entity needs some form of IT support to ensure that business operations are continuously running. As an entity grows in size and revenue, the information system needed to support the entity needs to grow as well. Some businesses may not have enough resources to accommodate this expansion. Their building may be too small or they cannot afford to purchase the equipment. When this is the case, an organization will choose to migrate their network infrastructure to a cloud computing environment. Cloud computing allows for a company to implement a large scale network without having to incur expenses for modifying the building infrastructure. Cloud computing can offer

In the last few decades, the increased capability and accessibility of Internet had resulted in many benefits to the world of computing. One of the most prominent contribution t to power cloud computing. Cloud computing, a relatively new technology, has experienced tremendous growth since its inception, with organizations and individual finding it beneficial, due to its convenience and ability to deliver computing resources at cost effective terms. The cloud offers on-demand cloud computing resources, eliminating the need for organizations to purchase, install, store and maintain costly computing infrastructure. It also offers reliability and flexibility in terms of computing. With the cloud model, users can have services in three paradigms. First, cloud as an infrastructure offers the users on-demand computing infrastructure, including

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

With the rapid change in processing and storage technologies and the success in the communication network such as Internet, lessen cost of computing resources, more powerful and more ubiquitously available than ever before. This technological change has enabled the development of a new computing paradigm called cloud computing, in which resources are shared by multiple system over the communication network. Cloud computing is a set of IT services that are provided to a business organizations or customers over a network on a leased basis and with the ability to scale up or down their service requirements. Cloud computing services are delivered by a third party provider who owns the infrastructure. Cloud computing has turned up as a new model for hosting and delivering services over the internet. Cloud computing becomes an attraction in the business world as it does not require plan for provision and business can be set up with a small amount.
