Cloud computing is one of the most popular areas of IT development. This is the provision of computing services servers, storage, databases, networks, software, and analytics and much more via the Internet ("cloud"). They are based on scaled and virtualized resources (data and programs) that are accessible to users through the Internet and implemented because of powerful data centers (data centers).

Internet is growing in many ways, be it the importance, functionalities, growth, users and last but not the least, the ease with which it can be accessed. Way back the access was via limited dialup connections at home, or the company network in the offices. Later its use was made easy with home broadband connections, Internet cafes, Wi-Fi based wireless hotspots and now the access is as simple as a click or simple touch, appreciation to smartphones, iPhones and other smart mobile devices that have made the use as easy and essential as breathing in. Not to forget the advent of Cloud computing that has become as an important paradigm to overcome problems faced by organizations to use expensive software and other services. It is one of the most important archetype shifts of the past decades. The approach promotes deployment of services with security, good performance and maintenance and various other remarkable features. This paper highlights computing technologies that are so much eng...

—Cloud computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data and information rather than a local server or a personal computer. Cloud computing is a better way to run your business. Instead of running your apps yourself, they run on a shared data center. The actual term "cloud" borrows from telephony in that telecommunications companies, who until the 1990s primarily offered dedicated point-to-point data circuits, began offering " VIRTUAL PRIVATE NETWORK (VPN) " services with comparable quality of service but at a much lower cost. The cloud symbol was used to denote the demarcation point between that which was the responsibility of the provider from that of the user. Cloud computing extends this boundary to cover servers as well as the network infrastructure. Cost is claimed to be greatly reduced and capital expenditure is converted to operational expenditure. Device and location independence enable users to access systems using a web browser regardless of their location or what device they are using. It's a new era Technology which is famous in Different areas like Business, Education, medical research etc. In this paper we are introducing some applications of cloud Computing such as email,virtual application access,e-learning,backup of online data,with the areas where we can implement these application., we are also focused on real time appliactios of cloud computing. In this paper we focused on different service models of cloud computing such as SAAS,PAAS,IAAS.In Infrastrure as services we have explained private,

While the topic of Cloud Computing has become prevalent in the last few years (roughly from 2006 onwards), the industry's leading IT companies trying to enter this category and applying it in their service processes. customers and users have. So that the top of today's IT world, cloud computing as a major competitive advantage over companies that use their rank. Cloud computing as a new mode of network applications for the development of infrastructure of the Internet. [3]. In this paper a general introduction to the topic of cloud computing deal Subsequent layers of the important features of cloud computing will be mentioned Finally, a comparative assessment of the country and the world will focus on this area.

IT has changed us profoundly. It has changed our culture, it has changed our language, and it has even changed the way we think. Cloud computing is the most significant development for IT since the invention of the PC. Moreover, "cloud media" is an extension of the cloud computing. It is based on the idea that media applications and IT-based services that previously required some sort of local application or storage device are now moving off of local PCs and onto data center servers. Today, there are a variety of services that bring functionality to business and consumers via Web-based applications that were previously PCcentric and/or local server applications. Software as a Service (SaaS) applications such as Google Apps and CRM software from Salesforce or Amdocs are great examples of this. These services are not only focused on people but on businesses as well, thus enabling cloud media to affect not only IT itself but more importantly IT's relationship with the business. One could say that cloud media is potentially the game-changing paradigm that will rewrite the way companies view, use and pay for technology. In this paper we will study the ways in which cloud media can change the way business is done, not only in terms of organization, but also the complete organizational behavior of a company.

The project involves study of cloud computing basics and terminologies. The aim is to show how services are deployed to the internet users as well as organization via a medium or concept called as cloud. Cloud computing increases optimized use of resources such as servers, software and infrastructure. Cloud is simply a concept of putting services on a common central point so that it can be distributed across several users at any place. Having several advantages cloud computing is a trending discipline which must be adopted by users so as to increase optimized use of services in form of software, hardware and infrastructure which benefits to the user or organization in form of cost effectiveness, reusability, choice making and change management.

Now a days the work is being done by hiring the space and resources from the cloud providers in order to do work effectively and less costly. This paper describes the cloud, its challenges, evolution, attacks along with the approaches required to handle data on cloud. The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer. The need of this review paper is to provide the awareness of the current emerging technology which saves the cost of users.

Cloud Computing is becoming the most reliable and efficient way to share hardware, software and platform in form of services via Internet. The elastic nature of cloud computing has attracted all strata of business enterprises ranging from small scale to large scale organizations such as Google, IBM, Amazon and the list goes on. The era of Cloud computing has just begun so there are challenges along with the opportunities

Cloud computing now easily tops any list of topics in computer science because of its far reaching involvements in many areas in computing, especially Big Data. Moreover, It is a one of the most emerging technology due to the provision of various computing infrastructure and services. Cloud computing has evolved through a number of phases that include mainframe computing, cluster computing, and grid computing, parallel computing, distributed computing and utility computing. Cloud computing is often considered the successor of grid, cluster and, mainframe computing. Cloud computing is the delivery of many services through the Internet. These resources include tools and applications like databases, infrastructure, platforms, data storage, servers, networking, and software. Many people and businesses use cloud for a number of reasons including cost savings, increased productivity, speed, efficiency, high performance, scalability, high computing power and security. This paper presents the definition of cloud computing, its characteristics, different cloud services and various platforms that are used in cloud computing.
