A Survey on Cloud Computing Simulation and Modeling

Ilyas Bambrik
2020 SN Computer Science  
The economical model proposed by this technology is a viable solution for consumers as well as being a profitable one for the provider.  ...  Although the models proposed by these simulators are not exhaustive, each one is made to address a specific process.  ...  Thus, when a checkpoint operation is executed, a slave host is selected randomly to save the checkpoint which limits I/O congestion.  ...

Efficient Deduplication in a Distributed Primary Storage Infrastructure

João Paulo, José Pereira
2016 ACM Transactions on Storage  
The evaluation of an open-source prototype shows that minimal I/O overhead is achievable even when deduplication and intensive storage I/O are executed simultaneously.  ...  However, traditional archival and backup deduplication systems impose prohibitive storage overhead for virtual machines hosting latency-sensitive applications.  ...  ACKNOWLEDGMENT We thank the DAIS'14 reviewers for their comments on earlier versions of this article.  ...
