SURVEY ON EFFICIENT AND ENHANCED RESOURCE ALLOCATION FOR WORKFLOW IN CLOUD COMPUTING
Journal Title: Elysium Journal of Engineering Research and Management - Year 2016, Vol 4, Issue 6
Abstract
Cloud computing is delivery of services over internet that shares the resources on demand. Resources utility can be increased or decreased as per demand. Cloud computing offer users to pay only for what they use and work load they use. Cloud computing mainly reduces the cost by sharing the resources. Clouds are used in real time application like Google Email Communication, Google Docs, Microsoft Sky Drive and Amazon S3, Google Drop box. Cloud allows us to access on-demand applications and associated data from anywhere. There is no need to purchase storage resources, computational resources because all these features are provided by the cloud service provider, and also eliminates the need for IT mangers. Pay-as-you-go model charges the user who makes use of on-demand resources. Major drawback in cloud is optimizing the utilization of allocated resources. Resource sharing is the objective of minimizing the costs associated with it. Other drawbacks in cloud are sharing infrastructure based on user need, because it is so difficult to balance between resource allocation and on demand service. Nowadays highly confidential data like healthcare and military records are stored in cloud. There are many security issues while storing the data in clouds. Data are stored in third-party cloud service provider which user may not fully trust. So we propose an efficient attribute-based encryption method to encrypt the data and store it in cloud.
