The recent decade witnesses the prevalence of hybrid storage systems that offer storage based on diverse storage devices to achieve both cost savings and performance improvements. However, there have been little of studies focusing on the challenging scenario of providing hybrid block storage for Virtual Machines (VMs), which is subject to several stringent(More)
Cloud computing is the latest computing paradigm that delivers IT resources as services in which users are free from the burden of worrying about the low-level implementation or system administration details. On the other hand, within the era of information explosion, some websites may encounter a sharp rising workload due to some unexpected social(More)
This paper presents the design, implementation, and evaluation of a multi-tiered storage system called MOBBS, which provides hybrid block storage for Virtual Machines (VMs) on top of object-based storage infrastructure. MOBBS is mainly motivated by the gap between the lack of studies on hybrid block storage for VMs and the increasing prevalence of hybrid(More)
Because of its high IO performance, Solid State Drives (SSDs) are playing an important role in cloud storage services. However, its ten times price of Hard Disk Drives (HDDs) makes it unaffordable for most companies to replace all traditional HDD storage with high performance SSD storage. Hybrid storage becomes a trade-off solution between relatively high(More)
