Cloud Computing
Cloud computing is a type of computing that depends on sharing computing resources rather than having local servers or personal device to handle applications.
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.
It allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. E.g. Yahoo mail, Gmail, Hotmail.
Cloud computing is provides on-demand self-service.
Service Models:-
A cloud service is any resource that is provided over the internet. Service delivery in cloud computing comprises three different service models.
• Software-as-a-service (Saas):-
Saas is the model in which an application is hosted as a service to customers who access it via the internet. E.g. Google docs, salesforce.com, CRM, ERP, email, social networking.
It provides significant efficiencies in cost and delivery in exchange for minimal customization and represents a shift of operational risks from the consumer to the provider.
User of Saas offering usually has neither knowledge nor control about the underlying infrastructure.
• Platform-as-a-service(Paas):-
This kind of cloud computing provides development environment as a service.
The consumer can use the middleman’s equipment to develop his own program and deliver it to the users through internet and servers.
It provides a well organized and graceful approach to operate scale-out applications in a predictable and cost effective manner.
The consumer controls the application that...

• Community cloud:-
A community cloud is controlled and used by a group of organizations that have shared interests, such as specific security requirements or a common mission.
• Hybrid cloud
A hybrid cloud is a combination of a public and private cloud that interoperates.

The second cloud infrastructure that I would like to describe is the Software as a Service model, which is also known as SaaS. The SaaS model provides a broad scope of devices that are able to access software programs from one company’s applications. System as a service was developed to run applications from any device or user that has permission from the host. The book states, “Online email services, such as Gmail and Yahoo!, are good examples of SaaS” (Jill West, 2016). Cengage Learning made the Software as a
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
OpenStack is an open-sourced company independent private cloud platform built with segregated resource pools that can interconnect. For example, a virtual machine can be created using OpenStack Nova, which will connect into the block storage component to store data. The same server can be connected into a vLAN(virtual network) to have other servers throughout various locations connect to one network without costly networking hardware. Configuration is relatively easy as there is need to count, track or monitor which servers have the software installed. Managing the VMs created in OpenStack Nova is also easy as it is possible to use the CLI from the browser through a VNC proxy. In fact, all of the resources and modules can be managed from the browser.
Cloud computing is defined by experts as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The meaning behind the word cloud is that it is a metaphor for the entire online web and its data as well. A cloud service differs from traditional hosting in three different ways. These three differences are that cloud computing is elastic, it is sold on demand, and the service is managed by the provider of the cloud. The easiest way to explain what cloud computing does is that it stores and gives access to different data and programs over the internet rather than just your computer’s hard drive. For it to be actually considered cloud computing it must include data or programs over the internet. Cloud computing can be done anytime, anywhere with an online connection.

Possibly the future of online banking and digital finance, Blockchain is shrouded in mystery and skepticism. What is Blockchain? According to CIO Journal article of the same name as the question, it is a “data structure that makes it possible to create a digital ledger of transactions and share it among a distributed network of computers” (Norton, p. 2). Unlike legal tender, Blockchain is dissimilar and arguably superior because it innovates the process by allowing companies to create, verify, and monitor transactions on a network instantly without a governing source (Norton, p. 1). Essentially, Blockchain allows peer-to-peer networking safeguarded by security networks imbedded in the system.
Saas will provide customer service on demand. That is, Saas service uses scalability the data to remove the unrequired resources and also provide resources on demand. While locally hosted service will provide with whole data even if it is not required.
Cloud computing is the transfer of computing data or information into Internet. Cloud computing services allows individuals and businesses to
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.

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).”
Cloud storage basic terms, is a way to save information to the web that can managed data storage. Cloud computing services are online services, which store this information to a safe and secure location online. It’s offered a quicker, easier and safer backup than conventional methods of file storage such as bookshelves or cardboard files.
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.
