VMbuddies: Coordinating Live Migration of
Multi-Tier Applications in Cloud
Environments
Abstract
Enabled by virtualization technologies, various multi-tier
applications (such as web applications) are hosted by virtual machines
(VMs) in cloud data centers. Live migration of multi-tier applications
across geographically distributed data centers is important for load
management, power saving, routine server maintenance and quality-of-
service. Different from a single-VM migration, VMs in a multi-tier
application are closely correlated, which results in a correlated VM
migrations problem. Current live migration algorithms for single-VM
cause significant application performance degradation because
intermediate data exchange between different VMs suffers relatively low
bandwidth and high latency across distributed data centers. In this paper,
we design and implement a coordination system called VMbuddies for
correlated VM migrations in the cloud. Particularly, we propose an
adaptive network bandwidth allocation algorithm to minimize the
migration cost in terms of migration completion time, network traffic
and migration downtime. Experiments using a public benchmark show
that VMbuddies significantly reduces the performance degradation and
migration cost of multi-tier applications.

Supporting privacy protection in personalized web search Personalized web search (PWS) has demonstrated its effectiveness in improving the quality of various search services on the Internet. However, evidences show that users’ reluctance to disclose their private information during search has become a major barrier for the wide proliferation of PWS. We study privacy protection in PWS applications that model user preferences as hierarchical user profiles. We propose a PWS framework called UPS that can adaptively generalize profiles by queries while respecting user specified privacy requirements.

A Fast Fault-Tolerant Architecture for Sauvola Local Image Thresholding Algorithm Using Stochastic Computing Binarization plays an important role in document image processing, particularly in degraded document images. Among all local image thresholding algorithms, Sauvola has excellent binarization performance for degraded document images. However, this algorithm is computationally intensive and sensitive to the noises from the internal computational circuits. In this paper, we present a stochastic implementation of Sauvola algorithm. Our experimental results show that the stochastic implementation of Sauvola needs much less time and area and can tolerate more faults, while consuming less power in comparison with its conventional implementation.

J.

INTRODUCTION Cloud computing is being rapidly adopted across the IT industry, driven by the need to reduce the total cost of ownership of increasingly more demanding workloads. Within companies, private clouds are offering a more efficient way to manage and use private data centers. In the broader marketplace, public clouds offer the promise of buying computing capabilities based on a utility model. This utility model enables IT consumers to purchase compute resources on demand to fit current business needs and scale expenses associated with computing resources. Thus, cloud computing offers IT to be treated as an ongoing variable operating expense billed by usage rather than requiring capital expenditures that must be planned years in advance. Advantageously, operating expenses can be charged against the revenue generated by these expenses directly. In contrast, capital expenses incurred by the purchase of a system need to be paid at the time of purchase, but can only be depreciated to reduce the taxable income over the lifetime of the system. THE MAIN ATTRIBUTES OF CLOUD COMPUTING The main attributes of cloud computing are scalable, shared, on-demand computing resources delivered over the network, and pay-per-use pricing. This offers flexibility in using as few or as many IT resources as needed at any point in time. Thus, users do not need to predict future resources they might need, and to commit to capital investment in hardware. This is especially advantageous for start-ups, and small and medium businesses which might otherwise not be able to afford the IT infrastructure they need to support their growing business. At the same time, redirecting capital investment from IT infrastructure to the core business is attractive even for large and financially strong businesses. From a technical perspective, cloud computing brings the benefits of virtualization and multi-tenancy to scale-out systems. Virtualization techniques allow multiple system images to share the same hardware resources: CPU virtualization techniques create multiple virtual hardware systems, while network virtualization .

As virtualization is proving to be dominant in enterprise and organizational networks there is a need for operators and administrators to pay more attention to live migration of virtual machines (VMs) with the main objective of workload balancing, monitoring, fault management, low- level system maintenance and good performance with minimal service downtimes. It is also a crucial aspect of cloud computing that offers strategies to implement the dynamic allocation of resources. Virtualization also enables virtual machine migration to eliminate hotspots in data centers .However the security associated with VMs live migration has not received thorough analysis. Further, the negative impact on service levels of running applications is likely to occur during the live VM migration hence a better understanding of its implications on the system performance is highly required. In this survey we explore the security issues involved in live migration of VMs and demonstrate the importance of security during the migration process. A model which demonstrates the cost incurred in reconfiguring a cloud-based environment in response to the workload variations is studied. It is also proved that migration cost is acceptable but should not be neglected, particularly in systems where service availability and response times are imposed by stringent Service Level Agreements (SLAs). A system that provides automation of monitoring and detection of hotspots and determination of the new mapping of physical to virtual resources and finally initiates the required migrations based on its observations is also studied. These are experimented using Xen Virtual Machine Manager. Migration based resource Managers for virtualized environments are presented by comparing and discussing several types of underlying algorithms from algorithmistic issues point of view.

Cloud computing is a construct that allows us to access applications that actually reside at a location other than your computer, most often, this will be a distant data center. Many organizations have already started implementing these technologies to further reduce costs through improved resource utilization. Cloud Computing and virtualization enable users to use applications on internet and intranet. In Cloud computing many of the services relies heavily on virtualized hardware. Because of this, we carefully reviewed existing virtual hardware services in order to both understand how the process works and to find the service that is best suited to Cloud computing and virtualization in different situations. Keywords—Cloud Computing; Virtualization; Virtual Machine; Resource Utilisation; Data Center. I. INTRODUCTION In Cloud computing, virtualization is the basis of delivering Infrastructure as a Service (IaaS) that separates data, network, applications and machines from hardware constraints. Cloud computing is becoming popular among IT businesses due to its agile,flexible and cost effective services being offered at Software, Platform and In-frastructure level. Software as a Service (SaaS) allows users to access applications hosted by different vendors on Cloud via internet. Platform as a Service (PaaS) enables developers to code, test and deploy their applications on IaaS. In infrastructure as a Service (IaaS) model, Cloud provider’s offer services such as computing, network, storage and databases via internet. IaaS is the base of all Cloud services with PaaS and SaaS both built upon it. The primary features of IaaS are elasticity and virtualization. Virtualization enables a single system to concurrently run multiple isolated virtual machines (VMs), operating systems or multiple instances of a single operating system (OS) [1]. Cloud Suite relies heavily on virtualized hardware. Because of this, we carefully reviewed existing virtual hardware services in order to both understand how the process works and to find the service that is best suited to Cloud Suite. Virtualization is one of the oldest areas of interest in computer science. One of the most successful examples of virtualization is the Java Virtual Machine (J V M) [3]. Using the J V M allows the Java programming language to produce identical results regardless of the instruction set architecture (ISA) that is used by the hardware platform. This is because, for all intents and purpo ...

A Fast-Acquisition All-Digital Delay-Locked Loop Using a Starting-Bit Prediction Algorithm for the Successive-Approximation Register This brief presents a fast-acquisition 11-bit all-digital delay-locked loop (ADDLL) using a novel starting-bit prediction algorithm for the successive-approximation register (SBP-SAR). It can effectively eliminate the harmonic lock and the false lock. The achievable acquisition time is within 17.5-23.5 or 17.5-32.5 clock cycles when the ADDLL works at the low or high clock rate, respectively. The digital-controlled delay line and the SBP-SAR of the ADDLL chip are synthesized using Taiwan Semiconductor Manufacturing Company's (TSMC's) 0.18-μm CMOS cell library. The proposed ADDLL can operate at a clock frequency from 60 MHz to 1.1 GHz.

A Dynamically Reconfigurable Multi-ASIP Architecture for Multistandard and Multimode Turbo Decoding The multiplication of wireless communication standards is introducing the need of flexible and reconfigurable multistandard baseband receivers. In this context, multiprocessor turbo decoders have been recently developed in order to support the increasing flexibility and throughput requirements of emerging applications. However, these solutions do not sufficiently address reconfiguration performance issues, which can be a limiting factor in the future. This brief presents the design of a reconfigurable multiprocessor architecture for turbo decoding achieving very fast reconfiguration without compromising the decoding performances.

Interleaved Digital Power Factor Correction Based on the Sliding-Mode Approach This study describes a digitally controlled power factor correction (PFC) system based on two interleaved boost converters operating with pulsewidth modulation (PWM). Both converters are independently controlled by an inner control loop based on a discrete-time sliding-mode (SM) approach that imposes loss-free resistor (LFR) behavior on each cell. The switching surface implements an average current-mode controller so that the power factor (PF) is high. The SM-based digital controller is designed to operate at a constant switching frequency so that the interleaving technique, which is recommended for ac-dc power conversion systems higher than 1 kW, can be readily applied. An outer loop regulates the output voltage by means of a discrete-time proportional-integral (PI) compensator directly obtained from a discrete-time small-signal model of the ideal sliding dynamics. The control law proposed has been validated using numerical simulations and experimental results in a 2-kW prototype.

Bumpless Control for Reduced THD in Power Factor Correction Circuits It is well known that power factor correction (PFC) circuits suffer from two fundamentally different operating modes over a given AC input cycle. These two modes, continuous conduction mode (CCM) and discontinuous conduction mode (DCM), have very different frequency-response characteristics that can make control design for PFC circuits challenging. The problem is exacerbated by attempts to improve efficiency by dynamically adjusting the PWM switching frequency based on the load. Adjusting the PWM frequency based on the load limits controller bandwidth and restricts dynamic performance. Prior work has made use of multiple controllers, however, they have not addressed the discontinuity (bump) that exists when switching between controllers. In this paper, bumpless controllers will be synthesized for a 750 watt, semi-bridgeless PFC for the CCM-DCM operating modes.

A bidirectional single-stage three-phase Rectifier with high-frequency Isolation and power factor Correction This paper proposes a single-stage three-phase rectifier with high-frequency isolation, power factor correction, and bidirectional power flow. The presented topology is adequate for dc grids (or smart-grids), telecommunications (telecom) power supplies, and more recent applications such as electric vehicles. The converter is based on the three-phase version of the dual active bridge (DAB) associated with the three-state-switching cell (3SSC), whose power flow between the primary and secondary sides is controlled by the phase-shift angle. A theoretical analysis is presented and validated through simulation and experimental.

A Bidirectional Three-Level LLC Resonant Converter With PWAM Control This paper proposes a bidirectional three-level LLC resonant converter with a new pulse width and amplitude modulation control method. With different control signals, it has three different operation modes with different voltage gains. Therefore, it can achieve wide voltage gain range by switching among these three modes, which is attractive for energy storage system applications needing wide voltage variation. The proposed topology operates with constant switching frequency, which is easy to implement with digital control, and it can achieve soft switching for all the switches and diodes in the circuit as a conventional LLC resonant converter. The performance of the proposed converter is validated by the experimental results from a 1-kW prototype with 20 A maximum output current.

Efficient Single Phase Transformerless Inverter for Grid-Tied PVG System With Reactive Power Control There has been an increasing interest in transformerless inverter for grid-tied photovoltaic (PV) system due to low cost, high efficiency, light weight, etc. Therefore, many transformerless topologies have been proposed and verified with real power injection only. Recently, almost every international regulation has imposed that a definite amount of reactive power should be handled by the grid-tied PV inverter. According to the standard VDE-AR-N 4105, grid-tied PV inverter of power rating below 3.68KVA, should attain power factor (PF) from 0.95 leading to 0.95 lagging. In this paper, a new high efficiency transformerless topology is proposed for grid-tied PV system with reactive power control. The new topology structure and detail operation principle with reactive power flow is described. The high frequency common-mode (CM) model and the control of the proposed topology are analyzed. The inherent circuit structure of the proposed topology does not lead itself to the reverse recovery issues even when inject reactive power which allow utilizing MOSFET switches to boost the overall efficiency. The CM voltage is kept constant at mid-point of dc input voltage, results low leakage current. Finally, to validate the proposed topology, a 1 kW laboratory prototype is built and tested. The experimental results show that the proposed topology can inject reactive power into the utility grid without any additional current distortion and leakage current. The maximum efficiency and European efficiency of the proposed topology are measured and found to be 98.54% and 98.29%, respectively.

Highly Reliable Transformerless Photovoltaic Inverters With Leakage Current and Pulsating Power Elimination This paper presents a transformerless inverter topology, which is capable of simultaneously solving leakage current and pulsating power issues in grid-connected photovoltaic (PV) systems. Without adding any additional components to the system, the leakage current caused by the PV-to-ground parasitic capacitance can be bypassed by introducing a common-mode (CM) conducting path to the inverter. The resulting ground leakage current is therefore well controlled to be below the regulation limit. Furthermore, the proposed inverter can also eliminate the well-known double-line-frequency pulsating power that is inherent in single-phase PV systems. By properly injecting CM voltages to the output filter capacitors, the pulsating power can be decoupled from the dc-link. Therefore, it is possible to use long-lifetime film capacitors instead of electrolytic capacitors to improve the reliability of the PV system. The mechanism of leakage current suppression and the closed-loop control of pulsating power decoupling are discussed in this paper in detail. A 500-W prototype was also built and tested in the laboratory, and both simulation and experimental results are finally presented to show the excellent performance of the proposed PV inverter.

Grid-Current-Feedback Active Damping for LCL Resonance in Grid-Connected Voltage-Source Converters This paper investigates active damping of LCL-filter resonance in a grid-connected voltage-source converter with only grid-current feedback control. Basic analysis in the s-domain shows that the proposed damping technique with a negative high-pass filter along its damping path is equivalent to adding a virtual impedance across the grid-side inductance. This added impedance is more precisely represented by a series RL branch in parallel with a negative inductance. The negative inductance helps to mitigate phase lag caused by time delays found in a digitally controlled system. The mitigation of phase-lag, in turn, helps to shrink the region of nonminimum-phase behavior caused by negative virtual resistance inserted unintentionally by most digitally implemented active damping techniques. The presented high-pass-filtered active damping technique with a single grid-current feedback loop is thus a more effective technique, whose systematic design in the z-domain has been developed in this paper. For verification, experimental testing has been performed with results obtained matching the theoretical expectations closely.

Delay-Dependent Stability of Single-Loop Controlled Grid-Connected Inverters with LCL Filters LCL filters have been widely used for grid-connected inverters. However, the problem that how time delay affects the stability of digitally controlled grid-connected inverters with LCL filters has not been fully studied. In this paper, a systematic study is carried out on the relationship between the time delay and stability of single-loop controlled grid-connected inverters that employ inverter current feedback (ICF) or grid current feedback (GCF). The ranges of time delay for system stability are analyzed and deduced in the continuous s-domain and discrete z-domain. It is shown that in the optimal range, the existence of time delay weakens the stability of the ICF loop, whereas a proper time delay is required for the GCF loop. The present work explains, for the first time, why different conclusions on the stability of ICF loop and GCF loop have been drawn in previous studies. To improve system stability, a linear predictor-based time delay reduction method is proposed for ICF, while a time delay addition method is used for GCF. A controller design method is then presented that guarantees adequate stability margins. The delay-dependent stability study is verified by simulation and experiment.
