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

摘要

The advent of cloud computing in recent years has sparked an interestudfrom different organizations, institutions and users to take advantage of webudapplications. This is a result of the new economic model for the InformationudTechnology (IT) department that cloud computing promises. The model promises audshift from an organization required to invest heavily for limited IT resources thatudare internally managed, to a model where the organization can buy or rent resourcesudthat are managed by a cloud provider, and pay per use. Cloud computing also promisesudscalability of resources and on-demand availability of resources. Cloud computing isudthe era of computing technology environment to increase the capacity or additionaludcapabilities enhancement requirement without investing in new infrastructure, trainingudnew personnel or purchase or update new licensing software. Once this happen, thisudwill involved more and more information, data or environment on individual andudcompanies are using cloud computing service. This scenario will impact security forudcloud computing environment, performance and services. Major concerning in cloududfrom enterprise customer are security which reduce of performance and service in cloududcomputing and complications of data privacy and integrity within cloud environment.udThese give much impact and effect with cloud computing services. The most significantudscenario are effect with cloud computing service are Identity within cloud services orudcloud architecture and secured digital authentication during provision services. Theudsecurity and privacy are most important elements that always consumers take seriouslyudto protect and defense from any vulnerability also breaches of trust in cloud computingudservices. The educational of awareness of security and privacy in cloud computingudservices are seriously needed to be in place for all model deployment inside cloududcomputing services.
