Data Replication-Based Scheduling in Cloud Computing Environment
Abstract— High-performance computing and vast storage are two key factors required for executing data-intensive applications. In comparison with traditional distributed systems like data grid, cloud computing provides these factors in a more affordable, scalable and elastic platform. Furthermore, accessing data files is critical for performing such applications. Sometimes accessing data becomes...
متن کاملA Survey of Dynamic Replication Strategies for Improving Response Time in Data Grid Environment
Large-scale data management is a critical problem in a distributed system such as cloud,P2P system, World Wide Web (WWW), and Data Grid. One of the effective solutions is data replicationtechnique, which efficiently reduces the cost of communication and improves the data reliability andresponse time. Various replication methods can be proposed depending on when, where, and howreplicas are gener...
متن کاملImproving Data Availability Using Combined Replication Strategy in Cloud Environment
As grow as the data-intensive applications in cloud computing day after day, data popularity in this environment becomes critical and important. Hence to improve data availability and efficient accesses to popular data, replication algorithms are now widely used in distributed systems. However, most of them only replicate the static number of replicas on some requested chosen sites and it is ob...
متن کاملA Survey on Dynamic Data Replication System in Cloud Computing
Cloud computing has been a huge-scale parallel with shared computing system. It comprises an accumulation of inter-related plus virtualized calculating resources which are managed to be one or more amalgamated calculating resources. The target of the survey is a mechanized evaluation or else explanation of proceeding events in cloud data replication system. Completely, 34 papers are accumulated...
