1.0 Introduction
Cloud computing nowadays are used widely not only in business area but also in schools especially in higher education. Cloud computing is used to store and to keep save user data in the ‘cloud’. Instead of transferring data using hard disk or any other methods, using cloud computing service can help store data to the cloud straight away. Cloud is a model for sending on-demand services, infrastructure, and application software using the network. For instance, Dropbox is one of the cloud computing services where it provides free storage to allow users to save photos, videos, or any documents that users wish to store and at the same time by using cloud computing, users are allow to share them easily. Cloud computing have many useful characteristics despite the usefulness of cloud computing, it also have drawbacks such as the security issues.
1.1 Characteristics
There are several main characteristics of cloud computing which include resource pooling, rapid elasticity and measured service. In order for resource pooling to work, the user will need to provide resources and gather them, therefore it can serve various consumers using multi-tenant model publicly. Resources might include processing, different kind of storage, memory and email service. Rapid elasticity is a cloud network or services which can be broadened and contract. It is never a troublesome job to add in or exclude new computers in the cloud. Nevertheless, as the amount of users increases, it means that the provider or the server will have to increase their strength. Whereas measured service is computing resource that can be control by both consumer and provider of the utilized service. The charges are based on per usage metrics which mean you pay for t...

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

INTRODUCTION: With cloud computing, Amazon has enabled the usage of internet and central remote servers to maintain data and applications and created an environment where connectivity and availability is unobtrusive and prevalent. Amazon offers two options for hosting applications and databases. Amazon EC2 with Elastic Block Storage allows one to run a MySQL database server on Elastic Compute Cloud, an Infrastructure-as-a-Service provider, with Elastic Block Storage (EBS). Meanwhile, another option called Amazon’s Relational Database Services (RDS) is a scalable relational database in the cloud with high availability.
To understand how cloud computing can be of value to an organization, it is important to us that we understand the cloud and its components. There are three different types of cloud computing services referred to as Infrastructure as a Service (IaaS), Software as a Service (SaaS) and Platform as a Service (PaaS). IaaS delivers cloud computing infrastructure servers, storage, network and operating systems as an on-demand service. SaaS is about software deploying over the Internet. PaaS allows a creation of web applications without the complexity of buying and maintaining the software and infrastructure. In this paper, I will suggest that Innovartus Technology Inc should use IaaS as a replacement for PaaS because IaaS is a rapidly developing field with resources such as better services, cost variability, utility pricing model and dynamic scaling.
When they wanted to save photos online instead of on your personal computer, they are able to use “cloud computing” service. Cloud computing means that the transfer of computing data or information over the internet. Not just to keep data in your personal computer, they are able to save the data on internet server to open their data in any computer. In this report we will walk through about what is cloud computing, what kinds of model did cloud computing have, types of cloud computing, benefits of cloud computing, and security.

The cloud model comprises five essential characteristics are on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured services. It also offers main three service models such as software as a service (SaaS),platform as a service (PaaS), and infrastructure as a service (IaaS )and four deployment models are public, private, community, or hybrid. The cloud architecture must illustrate the platform and software compon...
Cloud Computing gives good efficiency even for small service. Ex: Amazon S3 provides services for storage and retrieval of data in the Cloud. Data as small as 1 byte and as large as 5 GB or even more can be stored in Cloud servers. But, the storage service in Grid computing is well suited for data-intensive storage. Storing as small as 1 byte in data grid is not economically suited. The amount of data must be large for maximum benefit
Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.

With cloud computing being accessed from the internet, sensitive information about any student should be forbidden. The cloud is encrypted but does have risks of security, privacy, interoperability, or performance when selecting a public cloud. The steps to keep students privacy has been seen as a steady rising problem. A private cloud would be more ideal for deployment that can be scaled to determine what information is shared among the student body, teachers and administrative employees of that school district. With the scalability of a private cloud the cost of its use can be kept manageable. The rules of use with the cloud should be outline in a student handbook that is given to each student and parent at the beginning of each semester.
University can implement cloud computing since it often requires most advanced tools for teaching, sharing data and advanced instructions. Students working on a particular project from our university can virtually connect and work with other students from a different place with the help of cloud computing to achieve common goals and this can greatly help in gaining lots of
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.

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.
Abstract: Fog computing extends cloud computing, cloud computing provide data, compute, storage, and application services to end-user, also the fog computing also provide the services like data, compute ,storage and application to end user. But in cloud the main problem that occurs is security and now a days security and privacy both are main concern that needed to be considered. Fog Computing is not a replacement of cloud it is just extends the cloud computing by providing security in the cloud environment. With Fog services we are able to enhance the cloud experience by isolating users’ data that need to live on the edge. The main aim of the fog computing is to place the data close to the end user.The securityissues are mentioned in this paper.
