Customers often suffer from the variability of data access time in cloud storage service, caused by network congestion, load dynamics, etc. One solution to guarantee a reliable latency-sensitive service is to issue requests with multiple download/upload sessions, accessing the required data (replicas) stored in one or more servers. In order to minimize storage costs, how to optimally allocate data...
By processing sensory data in the vicinity of its generation, edge computing reduces latency, improves responsiveness, and saves network bandwidth in data-intensive applications. However, existing edge computing solutions operate under the assumption that the edge infrastructure will comprise a set of pre-deployed, custom-configured computing devices, connected by a reliable local network. Although...
The purpose of this research is to empirically examine the effect of third party auditor and quality service to cloud storage and user trust. This research is causal quantitative and use partial least square and path analysis. The research object is corporation users of cloud computing storage in listed corporation in Indonesia Stock Exchange. The sample size is 368 corporations and the results of...
Information Technology industries are in need of more storage space to store various types of data on cloud. Since data rate is continuously increasing, we need to utilize the storage space efficiently in terms of efficiency, computing speed, response time etc. Storage management in cloud environment aims to enhance performance of the data center by efficiently optimizing the underlying storage resources...
Give full play to the big data in the cloud computing environment application advantages has become an important information service mode of the era of Internet +, paper with information service quality evaluation as the main line, using fuzzy comprehensive evaluation method to analyze a set of cloud computing environment information service quality evaluation process, at the same time, using the...
Cloud computing data centers offer high available and reliable infrastructures for hosting critical applications and data. These data centers host hundreds of thousands physical machines to response to incoming workload as job executing. In this paper, we analyze the Google cloud cluster properties to investigate the relationship among machine failures, updates, and job failures. We present the statistical...
The paper proposes the method of building the electric power marketing business application system based on the cloud computing and microservices architecture technologies to solve the issues of the current system with the concentrated infrastructure and the monolithic architecture which are difficult to support the business processing in very large scale and the evolution of the electric power marketing...
It is becoming more common to see software applications taking advantage of the many RESTful web services available publicly to meet their needs rather than developing an in-house solution. This introduces the problem where failures can occur in the network or on the service provider outside the influence of a developer. This paper introduces a reliability-aware framework with a focus on availability...
Reliable storage is central component of data centers that support private or public cloud. Erasure coding has becoming increasingly popular alternative to replication for its capability in substantially cutting disk cost while delivering the same reliability. This paper reports the comprehensive results of using FPGA for accelerating erasure encoding and decoding algorithms. In particular, to accomplish...
The rapid growth of cloud services and the growing user demands on resources have led to the development and popularity of cloud networks. This environment gives users an impression of infinite resources so the resources can be used on demand. Cloud resource providers wish to gain the most efficiency from its own resources. Their main objective is to reduce cost and maximize revenue from providing...
The evolution of Video-on-Demand (VOD) technologies have revolutionized the way watching TV changed from passive reception to user-empowering. Nowadays, with the high market-penetration level of Smart TV achieved in the globe, VOD has become one of the main online applications on TV. Nevertheless, as the number of users and media files grows rapidly on demand, the load balance and storage capacity...
Today, cloud vendors host third party black-box services, whose developers usually provide only textual descriptions or purely syntactical interface specifications. Cloud vendors that give substantial support to other third party developers to integrate hosted services into new software solutions would have a unique selling feature over their competitors. However, to reliably determine if a service...
The replication is a key technique in cloud storage system to ensure reliability and availability. But in cloud storage system, nodes are heterogeneous and dynamic, and there is a large number of update message in the replica consistency maintenance process, which increase the system management and network overhead. In this paper, we propose a replication consistency maintenance strategy, CMTree....
The emerging vehicular applications demand for a lot more computing and communication capacity to excel in their compute-intensive and latency-sensitive tasks. Fog computing, which focuses on moving computing resources to the edge of networks, complements cloud computing by solving the latency constraints and reducing ingress traffic to the cloud. This paper presents a visionary concept on vehicular...
Cloud computing and, in particular, cloud storage, has successfully boosted a variety of applications, in several domains; with proven acceptance and benefits by end users. While peculiar features of the cloud, e.g., redundancy, scalability and accessibility, are still highly desirable, several new scenarios are nowadays emerging, which call for additional features and/or different interpretations...
Following the Service-Oriented Architecture, Cloud services are exposed as Web APIs (Application Program Interface), which serve as the contracts between the service providers and service consumers. With increasing massive and broad applications of Cloud-based development, a large number of diversified APIs are emerging. Due to their wide impacts, any flaw in the cloud APIs may lead to serious consequences...
Cloud service providers offer spot instances through highest bidding plans that are at a very economical price compared to other pricing plans, namely on-demand and reservation. The usage of spot instance enables utilization of idle resources and provide service for cost sensitive tasks. However, this approach introduces the problem of cloud capacity allocation to different pricing plans that will...
Cloud computing is a type of online based computing that gives shared computer dealing out resources & data to the computers. It is dreadfully challenging part to maintain the safety of all required data that are wanted in various applications for the user in cloud. The data stored in the cloud may not be wholly responsible. So, the cloud storage contributors are in charge for monitoring the data...
Day by day the use of memory is increases rapidly. A lot of data created every day so the data management is become a critical task. Most of time much amount of memory wastage because of same copies present on various locations. The process of eliminating the repeated or duplicates copies of data is called as Data deduplication. This data deduplication process is widely used in cloud storage to decrease...
Cloud computing enable users to avail the various services as per their wish. However, the quality about the service and its trust detail is not transparent to the user. In this paper, we propose a fuzzy logic based trust evaluation system that accepts the user's feedback in terms of fuzzy linguistic terms. The appropriate weight for the given feedback is calculated with the fuzzy inference system...
