    An architecture of computing that provides services over the internet on the demand and desires of users that pay for the accessible resources that are shared is refer as the cloud computing. These resources are shared over the cloud and users do not have to acquire them physically. Some of the shared resources are: software, hardware, networks, services, applications and servers. Almost every industry from hospitals to education is moving towards the cloud for storage of data because of managing the effective cost and time of organizing the resources physically on their space. Storage of data over the data centers provided in the form of clouds is the key service of the cloud computing. Users store their desired data on clouds that are publicly available over the internet and away from their boundaries in cost effective manner.  Therefore, techniques like encryption is used for obscuring the user’s information before uploading or storing to the shared cloud devices. The main aim of the techniques is to provide security to the data of users from unauthorized and malicious intrusions

    The need to constantly and consistently improve the quality and quantity of the educational system is essential. E-learning has emerged from the rapid cycle of change and the expansion of new technologies. Advances in information technology have increased network bandwidth, data access speed, and reduced data storage costs. In recent years, the implementation of cloud computing in educational settings has garnered the interest of major companies, leading to substantial investments in this area. Cloud computing improves engineering education by providing an environment that can be accessed from anywhere and allowing access to educational resources on demand. Cloud computing is a term used to describe the provision of hosting services on the Internet. It is predicted to be the next generation of information technology architecture and offers great potential to enhance productivity and reduce costs. Cloud service providers offer their processing and memory resources to users. By paying for the use of these resources, users can access them for their calculations and processing anytime and anywhere. Cloud computing provides the ability to increase productivity, save information technology resources, and enhance computing power, converting processing power into a tool with constant access capabilities. The use of cloud computing in a system that supports remote education has its own set of characteristics and requires a unique strategy. Students can access a wide variety of instructional engineering materials at any time and from any location, thanks to cloud computing. Additionally, they can share their materials with other community members. The use of cloud computing in e-learning offers several advantages, such as unlimited computing resources, high scalability, and reduced costs associated with e-learning. An improvement in the quality of teaching and learning is achieved through the use of flexible cloud computing, which offers a variety of resources for educators and students. In light of this, the current research presents cloud computing technology as a suitable and superior option for e-learning systems

Cloud-based solution seems to be the key for IT organizations who have a problem of budget constraints. Cloud Computing is a new paradigm in distributed computing presents many ideas, concepts, technologies, and the type of architecture that served as a service-oriented. According to Foster Cloud Computing is a "paradigm of distributed computing on a large scale are motivated by economic factors, which contains a set of virtualization abstract, dynamic scalability, setting the computing power, storage, platforms and services that can be accessed in accordance with the requirements by external customers through the Internet "(Foster et al., 2008). Objectives to be achieved in this research are: 1) To know how to develop online learning model based on cloud computing (cloud computing) for vocational education students (D-3) FT UNM's department of electronics engineering; 2) To know how to design online learning model based on cloud computing (cloud computing) for vocational education students (D-3) FT UNM's department of electronics engineering; 3) To know the result of the development of online learning based on cloud computing (cloud computing) for vocational education students (D-3) department of electronics engineering FT UNM may meet the criteria for a valid, practical, and effective. The method used in this research is the development of research methods (Research & Development), which focuses on online learning based on cloud computing (cloud computing). Students today can not live away from the Internet. Through programs such as facebook, twitter, instagram, and gmail, s tudents are accustomed to using cloud-based technology services (Ercan, 2010). Therefore, the students hope to be able to access digital technology services on campus anywhere and anytime, including cloud services that support social media. Likewise pendiidkan vocational students who are currently in the industry are already using advanced technology. So should students have to understand the process and the system. Besides, in the learning process also greatly contribute to improving student achievement, especially in the learning lab. Thus researchers are interested in developing research to develop an existing model into a new model in online learning based on cloud computing (cloud computing)

    The increasing interest of online learning is unquestionable nowadays, with MOOCs being taken by thousands of students. However, for online learning to go mainstream it is necessary that professors perceive that the effort required to prepare and manage an online course is manageable. Today, a myriad of inexpensive tools and services can be used to produce and manage online courses with unprecedented ease and without distressing the professor. For that, this paper proposes an architecture based on Cloud services that simplifies the process of managing an online course, from delivering on-demand fully customized remote laboratories to communication automation for student engagement and feedback gathering. This approach has been applied to produce, distribute and manage an Online Course on Cloud Computing with Amazon Web Services. The paper describes the methodology, tools and results of this experience to point out that it is possible to deliver online courses with automatically provisioned labs, with minimal management overhead, while still providing a high quality learning experience to a worldwide audience.Moltó, G.; Caballer Fernández, M.

    Real-time agreement and fulfilment of SLAs in Cloud Computing environments

    Full text link
    A Cloud Computing system must readjust its resources by taking into account the demand for its services. This raises the need for designing protocols that provide the individual components of the Cloud architecture with the ability to self-adapt and to reach agreements in order to deal with changes in the services demand. Furthermore, if the Cloud provider has signed a Service Level Agreement (SLA) with the clients of the services that it offers, the appropriate agreement mechanism has to ensure the provision of the service contracted within a specified time. This paper introduces real-time mechanisms for the agreement and fulfilment of SLAs in Cloud Computing environments. On the one hand, it presents a negotiation protocol inspired by the standard WSAgreement used in web services to manage the interactions between the client and the Cloud provider to agree the terms of the SLA of a service. On the other hand, it proposes the application of a real-time argumentation framework for redistributing resources and ensuring the fulfilment of these SLAs during peaks in the service demand.This work is supported by the Spanish government Grants CONSOLIDER-INGENIO 2010 CSD2007-00022, TIN2011-27652-C03-01, TIN2012-36586-C03-01 and TIN2012-36586-C03-03.De La Prieta, F.; Heras Barberá, SM.; Palanca Cámara, J.; Rodríguez, S.; Bajo, J.; Julian Inglada, VJ.
