An Adaptive Data Placement Architecture in Multicloud Environments
2020
Scientific Programming
Preserved Fulltext
To this end, we propose ADPA, an adaptive data placement architecture that can adjust the data placement scheme based on the time-varying data access pattern and subject for minimizing the total cost and ...
Users tend to store their data in geographical and diverse CSPs so as to avoid vendor lock-in. Static data placement has been widely studied in recent works. ...
An Adaptive Data Placement Architecture In this section, we present an adaptive data placement architecture with high cost-effective multicloud availability. en, we formulate the problem in the architecture ...
