In a modern telco cloud, network functions are performed by groups of single or interconnected virtual machines (VMs), which form virtualized network functions (VNFs). Securing these VNFs is both important and challenging, since the VNFs might be performing some mission critical operations and exchanging sensitive information among each other. The problem lies in the implementation of current cloud...
The green-house effect has been a major concern for all researchers and big company world-wide. This study reduces the power consumption of single server without degrading the quality of the service by focusing on minimizing the migration of Virtual Machine. Existing migration system for Virtual Machine does not perform well for kinds of load toward single server. Thus, a new algorithm is calculated...
Continuous evolution of virtualization-related technologies have benefit greatly flexibility and reliability of software system. However, although virtualization removes binding between application and server underneath, it complicates the regular runtime hierarchy into an intricate structure, where cross-layer monitoring and holistic evaluation becomes challenging. Currently lots of monitoring practices...
Centralized e-Learning technology has dominated the learning ecosystem that brings a lot of potential usage on media rich learning materials. However, the centralized architecture has their own constraint to support large number of users for accessing large size of learning contents. On the other hand, Content Delivery Network (CDN) solution which relies on distributed architecture provides an alternative...
In accordance with the resent advancement in Internet of Things (IoT), the needs for IoT experiment platform have been ever increasing. IoT system consists of various technologies such as networking, sensor controller, edge-side computing, server-side big data collections, analysis and their visualizations. An experimental environment that can handle the development and experiments of such an IoT...
Much of smart phone time is spent in using apps that connect to the Internet. Android, out of the box, does not provide network filtering or monitoring facilities. Security exploits and privacy leaks makes it necessary that we track network usage that could be happening behind our backs. We have built a “network ombudsman” framework service and an app that continuously monitors and logs the network...
The extreme growth in deployment of cloud based services along with applications requiring high computational complexity has had an adverse effect on energy consumption in data centers. When cloud data centers add more computing capacity and increase in size, they generate more heat, require extra cooling. To counter this effect, energy dissipation must be reduced. Servers consume power even when...
Placement of Virtual Machines (VMs) on physical servers is a challenging area of research and has received considerable interest among researchers in the field of Cloud Computing. This paper focuses on the reduction of cost in placing a set of VMs considering the constraints of available cloud resources. We have proposed a polynomial time heuristic to place VMs satisfying the constraints with the...
This work aims to provide details on how to build an automated Environment Controlled Poultry Management System (ECPMS) using low cost commodity hardware and open source software. An all-inclusive system was developed using RaspberryPi-3, used as a Linux embedded processing unit and ArduinoMega board for interfacing with array of sensors. The system has been systematically investigated for different...
When provided with more powerful or extra hardware, state-of-the-art Byzantine fault-tolerant (BFT) agreement protocols are unable to effectively exploit the additional computing resources: On the one hand, in settings with heterogeneous servers existing protocols cannot fully utilize servers with higher performance capabilities. On the other hand, using more servers than the minimum number of replicas...
The consolidation of services is a widely accepted technique for IaaS Cloud providers to reducing energy consumption and improving the utilization of their resources. This technique is based on distributing all services in the minimum amount of servers. This way, the overall energy consumption of the datacenter is reduced, as less servers are needed to be active. Traditionally, research has focused...
Lately, the advancement in circuit technology combined with the design of low cost embedded devices have resulted in an infiltration of the latter into everyday humans' lives. To exploit the full potential of ubiquitous embedded devices, a network is used for their inter-communication, offering advanced real-time monitoring. This paradigm, known as Internet of Things (IoT), is steadily consolidated...
This article selects load balancing system technology to analyze, combines the live migration technology of virtual machine, and studys the frame of virtual machine live migration as well as the mathematical model applied to concrete process of the migration. The article presents that the process of combining the specific strategies of load balance to the frame of live migration, that the simulation...
There are a few network environment used for institutions of higher learning for eLearning application. The world financial crises cause institution of higher learning struggling to maintain and update the technologies and infrastructures and try to provide the sufficient budget allocation for the network infrastructure. Cloud Services Data Centre network environment is one of the solution where they...
With the advent of cloud computing more and more IT and business organizations are migrating to cloud for its entrancing features of computing and storage infrastructure. At the same, security, privacy of cloud computing is not at satisfactory level. To make things worse, clouds inherent nature brought new set of security issues. Specially, the cloud storage causes dilemma between two important factors:...
Traffic light congestion normally occurs in urban areas where the number of vehicles is too many on the road. This problem drives the need for innovation and provide efficient solutions regardless this problem. Smart system that will monitor the congestion level at the traffic light will be a new option to replace the old system which is not practical anymore. Implementing internet of thinking (IoT)...
Economic denial of sustainability (EDoS) is an emerging threat of cloud computing. This new form of attack is a breed of DDoS attack that exploits the volatility of cloud consumers utility cost model. EDoS attackers fraudulently consume resources that result multiple cloud instances due to auto scaling feature of cloud. Consequently, affected cloud consumer ends up with an excessive amount of payment...
A number of benefits originate from the implementation of cloud computing. Cloud computing has been extensively implemented in organizations like companies and universities. However, in Indonesia cloud computing is not widely approved by universities yet. This condition can be caused by lack of trust of the universities in the risk of cloud computing implementation. This paper is intended to analyze...
The energy consumption of data centers has been increasing continuously during the last years due to the rising demands of computational power especially in current Grid- and Cloud Computing systems, which directly influence the increment in operational costs as well as carbon dioxide (CO2) emission. To reduce energy consumption within the cloud data center, it required energy-aware virtual machines...
With increased cloud adoption globally, the cloud service providers are setting up their data centers in various geographical location to cater the needs of diverse range of users across the globe. The cost of managing data center includes not only hardware, software costs but also the electricity costs prevailing at that location. The cost of electricity varies from location to location and it is...
