An Image Management System Implemented on Open-Source Cloud Platform

In Cloud computing, the IAAS provides services and calculation to users by virtual machines. The management of virtual machine images not only consumes a huge amount of storage space, but also gives large pressure on network transmission. By using deduplication technology in open stack, this article designed and implemented image management system, which uses static chunking(SC) to divide image file into data blocks, avoids duplication data blocks transmission on network by using fingerprint pre-transmission technology and reduces storage space by deploying kernel-space file system with deduplication in the image storage server. The experiments showes that the system not only reduces 80% usage of the virtual machine image storage, but also saves at least 30% of transmission time.
