The Importance Of Cloud Computing

Cloud computing is storing and surveying data and programs over the internet rather than the computer's hard drive. Moreover, the cloud is a personification for the internet. It is linked to flowcharts and presentations that epitomize a huge, server-farm infrastructure of the internet as a puffy, white cumulus cloud, acquiring connections and dispensing information as it floats.

Public Cloud - The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.

Cloud computing allows a user to store and access data and programs over the internet instead on their computer hardware (Griffith, 2015). The user is then able to access from anywhere or any internet-enabled device. There are three categories of service in cloud computing: SaaS stands for Software as a Service; IaaS is Infrastructure as a Service; and PaaS is Platform as a Service. Until recently, most users stored and accessed their programs via their hard drive, also known as local storage. What began as an alternative delivery system is swiftly becoming a way for Enterprises to reduce their IT spending while still providing multiple applications to various users. If a service has the following

The world is turning to cloud computing to manage data. Businesses are at the forefront of this new trend with companies such as Google, Amazon, Microsoft, and others leading the way by providing these services. What exactly is cloud computing? According to Turban & Volonino (2011), cloud computing is Internet- based computing in which shared resources (such as hard drives for storage) and software apps are provided to computers and other devices on- demand (p. 48).

Private Clouds - Private clouds are created for a specific organisation and provide access only for users within that organisation. They deliver resources from within firewall and should be controlled by company’s IT department. Private clouds are more expensive than public clouds but provide more security in respect to them. It can be managed by the company itself (on premise) or by a third party (off premise).

Over the past several years, cloud computing has been getting attention as a new computing model for providing flexible and on-demand infrastructures, platforms, and software as services. Cloud computing is a technology through exchange of information and software management. Cloud computing allows users to use computer technology without the installation in their computers. It allows users to access their files or data from any computer having an internet connection. Cloud computing provides more efficient computing by centralizing data storage, processing and bandwidth. This technology emphases on virtualization of the host server or the controlling computer. The server acts as a communication network through which information could be shared. The information can be stored, retrieved and shared as and when required through a widespread global platform.

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 examples for the public utility computing can be Google Application suite, Microsoft Azure, Zoho office and Amazon Web services. Private Cloud is other way round with internal datacenter of a business and applications services which are not available to public usage. These can be used within the organization for private usage by the management and employees of the organization. Cloud computing mainly constitutes the SaaS and utility computing excluding the private cloud.

An example of Public cloud: Microsoft Azure. Example Public Cloud Providers: Google and Amazon. One plus about a public cloud is under-utilization is eliminated because customers are only charged for what they are using. A private cloud type is defined as internal services of an organization or third party that is not accepted by the public user. Example: Eucalyptus. As stated even though it might be expensive compared to a public cloud it is more secured.

These businesses will see the most benefit from using cloud technology. Furthermore, people involved in cloud computing can be organized into two groups as well; the cloud providers and the cloud user’s. The cloud user’s take resources from the cloud and utilize data storage. Cloud providers house the hardware or equipment for the cloud and also manage it.

A cloud is a unique information technology (IT) environment which has been designed for the purpose of provisioning, scalable and measured information technology resources remotely. Cloud Computing Service provides IT as a service over the internet on demand basis and the payment is based on usage. Cloud computing services are provided from development platforms and full applications to servers and storage. Cloud computing is a pervasive advancement which gives a beneficiary way to the clients to benefit the cloud applications on interest. It refers to the network service in which services are provided with assured QoS, affordable computing infrastructures with an easy and simple access on demand and is enabled

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.

There are different levels of security and management requirements that fit almost all the companies. Cloud computing can be private, public and hybrid. Private cloud computing is data from business center deliver to internal

Cloud Computing today has really reached in cloud 9 position.It is ever rising field in software and hardware world.Cloud Computing provides the utilities remotely.The utility it provides can be remote Operating System or it can be storage space or any such software and hardware utility.The user of cloud utilizes this resources remotely without having them in his own local machine.The local machines cannot store huge amount of data and process it,so by using cloud user can store its data on cloud for further processing.Cloud Computing principles are the reason why cloud is gaining huge success and popularity.
