Cloud computing technology is a very known and popular paradigm in the field of Information technology. It is an incipient computing model which emanates from grid computing which is resulting into an emerging paramount concept in Information Technology. Vast number of operating systems and virtual servers are mutually dependent through the internet and allow sharable resources with each other. This generates expeditious and efficient computing speed. The concept of cloud computing is predicated on the time sharing of expensive resources and benefits of the providence of scale. The word Cloud originates from the well-known cloud shape which is expressed as a network in architectural system diagrams. Cloud computing applies traditional supercomputing to provide tremendous throughput computing power. Cloud computing allows user to execute simulated applications on a virtual server. In this report, we discuss about cloud computing technologies for example “Distributed File System (DFS), Map-Reduce, and Big tab”. [3] This cloud computing architecture is designed for, geographic information Services which contains functional utilization, perceptions, benefits, computing reserving data and infrastructure layers. We also discuss about software backdrops called as “D cloud”. D-Cloud provides a condition for analysis on the cloud elements using a particular structural configuration and implements large number of evaluations automatically as per the scenario. We also discuss about combining Peer to peer systems and technologies related cloud computing in order to construct a blueprint of the architecture and establish PC2, an open and free cloud computing platform.

The idea of accessing, storing, and processing data from online server or virtual server instead of local server is called as Cloud computing. When we store data in our hard disk which is very near to computer that is called as local storage and computing but Cloud computing doesn’t access data from our hard disk.
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 last few years has seen an explosion in the use of the Internet as a means for exchanging, free of charge, digital media by way of Peer-to-Peer (P2P) file sharing technologies. Initially, the practice was primarily limited to the swapping of music, in the form of MP3 files. The pervasiveness of broadband, the advent of newer file types, and the creation of more sophisticated technologies has subsequently made possible the exchange of other types as well – including movies, television shows and software. Again, for free.
Peer-to-peer (P2P) networks have had a staggering growth in the past few years. Since Napster, dozens of P2P networks have been created in its imitation. Due to the growing accessibility of broadband, which increases the speed of downloads, P2P networks generate nearly 1.8 billion downloads per month. Popularity and acceptance is still continually growing.
Creating a hybrid cloud which entails taking a strategic approach to cloud adoption by determining what data you want to move to the cloud to avoid unnecessary business disruptions and support customers’ needs.
Not long ago computers were non-existent in many homes. When computers were first introduced to the world, they were for the sole purpose of performing business functions. The only people who owned computers were large organizations. Eventually, computers were introduced into the homes of those who could afford to buy them. Today, just about everyone owns some form of system that they use daily to help manage their day-to-day operations. What many once survived without now seems impossible to do without. As technology continues to grow, it has a greater effect on families and the education system. Some companies such as Microsoft and Apple made it possible to reinvent a new form of technology that would change the world. Each company had some form of struggle and overtime had to keep up with the changes of time and the way people communicated. From the first day of its invention, organizations have had to steadily implement new operating systems to keep up with the demands of the people while staying afloat with competitors. The ways of life for many have changed as well as the way people communicate. It is evident that the history and uses of computers have changed the world but these computers could not perform without the operating systems. Various operating systems will be discussed, how they began and how they each changed since they were first introduced. Although, they all had a purpose each varied in how they performed and changed the lives of many and will continue in the near future.

Virtualization technologies provide isolation of operating systems from hardware. This separation enables hardware resource sharing. With virtualization, a system pretends to be two or more of the same system [23]. Most modern operating systems contain a simplified system of virtualization. Each running process is able to act as if it is the only thing running. The CPUs and memory are virtualized. If a process tries to consume all of the CPU, a modern operating system will pre-empt it and allow others their fair share. Similarly, a running process typically has its own virtual address space that the operating system maps to physical memory to give the process the illusion that it is the only user of RAM.
The cloud computing is the practice that enables access to the shared pool of configurable computing resources which can be dynamically provisioned. It refers to both the applications delivered as service as well as hardware and system software in the data centres that provide those services. The attractive features of cloud computing such as on-demand access, high scalability, reliability, cost savings, low maintenance and energy efficiency bring benefits to both cloud service consumers and providers.
Cyber Security as an International Security Threat National and International Security is a sum of the actions taken by countries and other organizations that can guarantee the safety and well being of their population. It is vital for a nation to pre-emptively discover what issues could affect their security, and take action to prevent any detrimental or harmful events from happening. With the development of technology and the transition into a more technologically savvy society, cyber security has become one of the most prevalent and important economic and national security issues that the United States will come to face. United States President Barack Obama has identified cyber security as a key issue the nation will face. President Obama declared that the “cyber threat is one of the most serious economic and national security challenges we face as a nation” and that “America's economic prosperity in the 21st century will depend on cyber security (“Foreign Policy Cyber Security,” 2013).”
Peer-to-peer (P2P) is a substitute network design to the conventional client-server architecture. P2P networks utilize a decentralised model in which each system, act as a peer, and serve as a client with its own layer of server functionality. A companion plays the role of a client and a server in the meantime. That is, the node can send calls to other nodes, and at the same time respond to approaching calls from other companions in the system. It is different from the traditional client-server model where a client can just send requests to a server and then wait for the server’s response.
Several types of cloud storage systems have been developed to supporting both personal and business uses. Cloud storage also a model of networked enterprise storage where the data is stored not only in the user's computer, but also in virtualized of storage, which generally hosted by third parties company.
Hybrid cloud is able to provide larger scale of environment. Private cloud and public cloud resource can be used to manage unexpected surges in workload.
Cyber security is the protection of networks, computers, programs and data from attack, damage or unauthorized access. This is important because a great number of our confidential information is on computers and transmit that data across networks to other computers. As of now cyber-attack is one of the transnational issues that we are concern about in the United States. If these private networks were hack our national security infrastructure will be in distress.
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
