Cloud Computing

Within the past 10 years our societies technological advantages have been somewhat space age like, even alien like characteristics. Technologies, which ten years ago only existed in our dreams but yet, have become reality. Things like, the revolutionary iPhone and its almost seamless touch-screen tech; as well as the new advancements in our cultures most prized possession, The Internet. In this subject-based paper, I will take a closer look into a fairly new emerging technology, which is simply referred to as…Cloud Technology. The synopsis will cover, what and how cloud technology works, its

customers” (p.6). It is imperative that cloud computing vendors have the pentest as a part of their tool box to offer perspective clients. According to gwu.edu. (2010), Amazon has published a policy that includes a procedure for customers to conduct a pentest.

(4) Platform as a Service - This offers a development environment as a service. You can use this technology to develop your own applications that run on the providers server.

These administrations are extensively separated into three classifications: Infrastructure-as-a-Service (Iaas), Platform-as-a-Service (Paas) and Software-as-a-Service (Saas). Cloud computing was named motivated by the cloud image that is frequently used over the Internet through diagrams or flowcharts. Input data is analysed, collected and stored in one big online server which an authorized particular person can get access to. Margaret Rouse (December 2010). Moreover, four deployment models that have been used to deliver cloud services are private, public, community and hybrid. Private cloud is used by single organization to be able to

Wide range of network access capacities-different devices such as desktop computers, mobile phones and tablet devices can be used to access the network. Amazon Web Services (AWS), Microsoft, Google, IBM and Salesforce.com use Cloud service. Whiles, New York Times and NASDAQ use AWS (NIST).

Cloud computing is the delivery of on-demand computing resources which include everything from applications to data centers over the Internet on a pay-for-use basis. Cloud computing is the result of evolution and adoption of existing technologies and paradigms. The goal of cloud computing is to allow users to take benefit from all of these technologies, without the need for deep knowledge about or expertise with each one of them. The cloud aims to cut costs, and help the users focus on their core business instead of being impeded by IT obstacles Cloud computing is so named because the information being accessed is found in the "clouds", and does not require a user to be in a specific place to gain access to it. The services are offered from data centers all over the world, which collectively are referred to as the "cloud." The idea of the "cloud" is to simplify the huge network connections and computer systems involved in online services. Cloud computing is a computing model, not a technology. In this model of computing, all the servers, networks, applications and other elements related to data centers are made available to IT and end users. Cloud computing is a type of computing that is comparable to grid computing. It relies on sharing computing resources rather than having local servers or personal devices to handle applications.

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.

Cloud computing provides three important types of services in the cloud environment: Software as a service (SaaS), Platform as a

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.

Infrastructure as a Service like Amazon Web services provides virtual server instances with unique IP addresses and blocks of storage on demand. Customers use the providers application program interface(API) to start, stop, access and configure their virtual servers and storage. In the enterprise, cloud computing allows a company to pay for only as much capacity as needed and bring as soon as more is required.

Microsoft: Microsoft has Microsoft® Sharepoint® online administration that considers distinctive sort of applications to be moved into the cloud, and Microsoft had as of now propelled its office application in cloud.

Cloud Computing is one of the emerging technologies which now represent a reality and a low-cost computing power resource which has gained popularity among all business categories, especially medium and small size, governmental or medical organizations, as more people are realizing the power and benefits of cloud environments. Cloud computing involves deploying groups of remote servers and software networks that allow different kinds of data sources be uploaded for real time processing to generate computing results without the need to store processed data on the cloud. Clouds can be classified as public, private or hybrid

Private cloud and Hybrid cloud: Among the numerous motivations for utilizing cloud, there are two circumstances where associations are investigating approaches to evaluate a percentage of the applications they mean to convey into their surroundings using a cloud (particularly an open cloud). While on account of test and improvement it might be restricted in time, embracing a hybrid cloud approach considers testing application workloads,

The technology used in Cloud Computing is often centralized on demand and can be offered in terms of services. Just like most internet service providers, the cloud services provide platforms for their clients to create web services (applications) on the internet. These applications are accessed through the web opposed to running off your local hard drive. Cloud computing enables its users to conveniently use various resources like storage, servers, and applications that can be launched with minimal effort. In common terms, cloud computing proposes three types of services: 1) SaaS: Software as a service, 2) PaaS: Platform as a service, and 3) IaaS: Infrastructure as a service. Cloud

1. Introduction The definition of Cloud Computing as issued by the U.S. National Institute of Standards and Technology (NIST) September, 2011 is: “Cloud computing is a model for enabling ubiquitous, 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 is composed of five essential characteristics, three service models, and four deployment models.” Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It provides an easy and flexible way of storing, retrieving huge data without bothering about the resources. With
