    In the case of a cloud-based remote control system that enables users to control cloud-connected devices from anywhere at any time, costs tend to increase in proportion to the number of devices. Most of the costs are derived from a message broker, a key component of the system that keeps connections from devices and relays messages between users and devices. In this paper, we analyze the costs of ... View full abstract»

    To support the migration of software applications to the cloud environment, cloud venders have proposed different migration methodologies and guidelines. Yet, most of them require human intervention, involving manually performing repetitive tasks. This paper proposes a pattern-based transformation approach for cloud application migration. The approach automatically modifies the source code of an a... View full abstract»

    While virtualized solutions are firmly entrenched in cloud data centers to provide isolated execution environments, the chief overhead it suffers from is that of memory consumption. Even pages that are common in multiple virtual machines (VMs) on the same physical machine (PM) are not shared and multiple copies exist thereby draining valuable memory resources and capping the number of VMs that can...

    NoSQL systems have grown in popularity for storing big data because these systems offer high availability, i.e., Operations with high throughput and low latency. However, metadata in these systems are handled today in ad-hoc ways. We present Wasef, a system that treats metadata in a NoSQL database system, as first-class citizens. Metadata may include information such as: operational history for a ... View full abstract»

    Cloud based video delivery platforms serve a significant fraction of the entire Internet traffic and are continuously expanding with the growing demand. We study the provisioning of the server cluster to deploy at each location in such systems. We optimize the right server count, peering bandwidth, and server configuration as the disk size and the necessary SSD and/or RAM caches to sustain the int... View full abstract»

    In this paper, we describe a method for transforming and migrating data schemas developed for RDBMS to HBase. The method consists of a set of HBase-organization guidelines and a four-step data-schema transformation process that HBase application developers may follow during the migration of their application data from RDBMSs to HBase. The method also considers data-access paths extracted from quer... View full abstract»

    Live Virtual Machine (VM) migrations are an important tool that is used in modern data centers in order to e.g. Consolidate server racks for maintenance or optimize VM placements across physical hosts. However, live VM migration causes a lot of network stress due to the potential large volume of data that is transmitted between the physical hosts, which may negatively impact other latency sensitiv...
