Object replication is an important and sophisticated question, it can reduce access latency and bandwidth consumption, replication can also help in load balancing and can improve reliability by creating multiple replicas of the same storage object. But there are many difficulties
Dynamic Replication Policy on HDFS Based on Machine Learning Clustering
Data growth in recent years has been swift, leading to the emergence of big data science. Distributed File Systems (DFS) are commonly used handle data, like Google System (GFS), Hadoop (HDFS), and others. The DFS should provide availability reliability system case failure. replic
The Dynamic Replication Mechanism of HDFS Hot File based on Cloud Storage
As an open source cloud storage scheme, HDFS is used by more and more large enterprises and researchers, and is actually applied to many cloud computing systems to deal with huge amounts of data. HDFS has many advantages, but there are some problems such as NameNode single point
Fault tolerant shared-object management system with dynamic replication control strategy
This paper is based on a dynamic replication control strategy for minimizing communications costs. In dynamic environments where the access pattern to share resources can not be predicted statically, it is required to monitor such parameter during the whole lifetime of the system
The spontaneous replication error and the mismatch discrimination mechanisms of human DNA polymerase β
To provide molecular-level insights into the spontaneous replication error and the mismatch discrimination mechanisms of human DNA polymerase β (polβ), we report four crystal structures of polβ complexed with dG•dTTP and dA•dCTP mismatches in the presence of Mg2+ or Mn2+. The Mg(
The Replica Management System: a scheme for flexible and dynamic replication
The actual gains achieved by replication are a complex function of the number of replicas, the placement of those replicas, the replication protocol, the nature of the transactions performed on the replicas, and the availability and performance characteristics of the machines and
An Efficient Data Replication Strategy in Large-Scale Data Grid Environments Based on Availability and Popularity
The data grid technology, which uses the scale of the Internet to solve storage limitation for the huge amount of data, has become one of the hot research topics. Recently, data replication strategies have been widely employed in a distributed environment to copy frequently acces
Cost Optimization for Dynamic Replication and Migration of Data in Cloud Data Centers
Cloud Storage Providers (CSPs) offer geographically data stores providing several storage classes with different prices. An important problem facing by cloud users is how to exploit these storage classes to serve an application with a time-varying workload on its objects at minim
Dynamic Replication and Migration of Data Objects with Hot-spot and Cold-spot Statuses Across Storage Data Centers
Cloud Storage Providers (CSPs) offer geographically dispersed data stores providing several storage classes with different prices. A vital problem faced by application providers is how to exploit price differences across data stores to minimize monetary cost of applications that
CLEAR: An Efficient Context and Location-Based Dynamic Replication Scheme for Mobile-P2P Networks
We propose CLEAR (Context and Location-based Efficient Allocation of Replicas), a dynamic replica allocation scheme for improving data availability in mobile ad-hoc peer-to-peer (M-P2P) networks. CLEAR exploits user mobility patterns and deploys a super-peer architecture to manag
