Enhancing the Performance of Metadata Service for Cloud Computing

Abstract

Efficient metadata management is critical for distributed file system in cloud computing. In this paper we propose a new metadata management scheme which employs master metadata server (MMDS) and metadata look-up table server between the metadata servers and clients. The MMDS checks the state of MDSs for load-balancing, and thereby avoids hot spot. The proposed scheme significantly reduces the network traffic as well.
