Managing Personalized Cross-cloud Storage Systems with Meta-code

Providing fine-level and customized storage solutions for novice cloud users is challenging. At best, a limited set of customization options are provided, often related to volume of data to be stored. We are proposing a radical different customization approach for cloud users, one where personalization of services provided is transparently managed and supported. Our approach to building personalized cloud storage services is to allow the user to specify data management policies that execute in a user space container transparently to the user. In this paper we describe Balva, a cloud management system that allows users to configure flexible management policies on their data. To support legacy applications, Balva is implemented at the file system level, intercepting system calls to effectuate dynamic and personalized management policies attached to files.
