Analysys on security issue of service dilevery model software as a service (SAAS) in public cloud computing

Abstract

The advent of cloud computing in recent years has sparked an interest from different organizations, institutions and users to take advantage of web applications. This is a result of the new economic model for the Information Technology (IT) department that cloud computing promises. The model promises a shift from an organization required to invest heavily for limited IT resources that are internally managed, to a model where the organization can buy or rent resources that are managed by a cloud provider, and pay per use. Cloud computing also promises scalability of resources and on-demand availability of resources. Cloud computing is the era of computing technology environment to increase the capacity or additional capabilities enhancement requirement without investing in new infrastructure, training new personnel or purchase or update new licensing software. Once this happen, this will involved more and more information, data or environment on individual and companies are using cloud computing service. This scenario will impact security for cloud computing environment, performance and services. Major concerning in cloud from enterprise customer are security which reduce of performance and service in cloud computing and complications of data privacy and integrity within cloud environment. These give much impact and effect with cloud computing services. The most significant scenario are effect with cloud computing service are Identity within cloud services or cloud architecture and secured digital authentication during provision services. The security and privacy are most important elements that always consumers take seriously to protect and defense from any vulnerability also breaches of trust in cloud computing services. The educational of awareness of security and privacy in cloud computing services are seriously needed to be in place for all model deployment inside cloud computing services.
