Cloud Computing and The Future
Introduction
Our future in computing is moving into a whole new direction called Cloud Computing. Many questions and issues have arisen from this new adventure in computing. For us to understand cloud computing we must first learn what it is. Once we have established that knowledge we can then venture out to the advantages and disadvantages, types of models, and finally services in cloud environments. We will see the correlation of information that leads into how cloud computing affects us today or in our near future.
Cloud Computing and The Future
What is cloud computing? Cloud computing is described as “dumb” terminals (Bowles, M.D. 2013, Chapter 9.4). In other words, it is a way of renting computers, storage and network by the hour from companies that have these resources already established in their data center. One of the companies that are utilizing this technique is Amazon.com and many other organizations are modeling their clouds after them. It works in a similar way as electricity, when you turn your lights on you are getting charged for the electricity that you are utilizing and when you shut the power off you are not being charged. Many companies charge you the same way as the utility company, you are only paying for the applications that you are utilizing. In a nutshell, you are using programs from many different servers. Examples of cloud computing are: iTunes, documents, Apps, calendar, backup data, and synchronization.
Types of Models
Cloud models are the physical arrangement of the infrastructure and the services the end user will receive. Here are a few types of models:
Private Cloud one has exclusive use of an isolated cloud.
Public Cloud th...

“Google and “Amazon” were the original firms that provided cloud computing services. “Google and “Amazon’s” analysts said that cloud computing was “on-demand access to virtual information technology resources” (Budriene, Zalieckaite, 2012, p.119). The cloud is simple, it allows businesses to access IT resources over the Internet. Budriene and Zalieckaite (2012), says “Cloud computing is a new conceptual paradigm for business which combines into a single environment not only applications, architecture and business models, but a variety of professionals for performance of common business tasks in the Internet medium,” (p. 120).
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. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.

Cloud computing can be defined as: “a variety of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet.” Our understanding of cloud computing is distributed computing over a network with the ability to run a program or application on many connected computers at the same time.
There is a lot of buzz about “the Cloud” and what it can and cannot do for IT departments. A wide range of products and services are lumped into the phrase “Cloud computing.” While the strict definition of a cloud speaks mainly to a collection of easily deployed virtual servers, it also encompasses vendors of outsourced exchange servers, preconfigured CRM applications, web-enabled word processing applications, and online backup services (Gohring, 2013).
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
The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network. A cloud is a combination of hardware, networks, storage, services, and interfaces that helps in delivering computing as a service. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. In addition, the platform provides on demand services to the users for accessing that are always on anywhere, anytime and any place. Cloud computing platform provides the scalability, availability and utility computing for services on Internet.

Cloud computing : Cloud computing is a new class of network based computing that takes place over the internet. Large number of remote servers are allow to centralized data storage and there is online access to computer resources and services.
In the 1950s Cloud computing started with mainframe computing, where multiple users were able to access a central computer by using a dumb terminal, which had only one function, and that was to provide access to the mainframe. In the 1970s, the concept of virtual machines was created, by using the virtual machine technology it was possible to used more than one operating system simultaneously in a secluded environment. In 1993 cloud computing reached its first milestone with e-mail, which is a method of exchanging information/ data or digital messages through a computer network of the internet. Emails were originally a text based form of communication only, these days’ files like multimedia, images or PDFs can be attached. Today, cloud computing is a part of our everyday lives, we still use it to email, and now we use a more perfected cloud system to store applications or files and can access them anywhere and anytime.
Cloud computing is sort of like the first computers come full circle – in the early days of computing, users at terminals with no computing power to speak of made use of the number-crunching capabilities of mainframes in a shared fashion – in fact, the model of computer use was called “time-sharing.” As the personal computer grew in power and capabilities while also becoming a cheap...

The term used as cloud computing is a wide term. It includes a wide range of different services. Cloud computing is also known as on demand computing. This name is given to cloud computing because it provide online services to different persons on computer by sharing processing resources in addition with data to computers depending upon different demands.
Cloud computing is the transfer of computing data or information into Internet. Cloud computing services allows individuals and businesses to
Cloud computing is a type of computing that depends on sharing computing resources rather than having local servers or personal device to handle applications.
