ABSTRACT is a recently emerged model which is becoming popular among almost all enterprises. It involves the concept of on demand services which means using the cloud resources on demand and we can scale the resources as per demand. Cloud computing undoubtedly provides unending benefits and is a cost effective model. The major concern in this model is Security in cloud. This is the reason of many enterprises of not preferring the cloud computing. This paper provides the review of security research in the field of cloud security. After security research we have presented the working of AWS (Amazon Web Service) cloud computing. AWS is the most trusted provider of cloud computing which not only provides the excellent cloud security but also provides excellent cloud services. The main aim of this paper is to make as a core operation and not an add on operation.

V. CONCLUSION Online education is reconfiguring the delivery of schooling and the activities that students experience on a daily basis. However, our analyses show that the analyses also support what charter advocates have long suspected: that e-schools drag down the impact of the state’s charter sector. Our findings reveal some important considerations for Ohio policy makers as they consider the future place of online learning within K–12 education. They also highlight key questions and challenges that policy makers, advocates, and educators ought to bear in mind, and properly address, as the adoption of technology in education increases in the coming years.
