Consistency tradeoffs on distributed multi-datacentric systems
Balla W. Diack, Samba Ndiaye, Yahya Slimani · 2015
Distributed systems in the cloud computing context spread data across geographically remote datacenters to ensure always availability, scalability, and a best reactivity.Choosing latter properties in these systems leads to consistency issues (version conflicts, obsolete data, etc.); besides, most analytical solutions suggested for these issues are incomplete.SCOLCH proposes tradeoffs to achieve the required properties for service level agreement in cloud computing.
