By George Kousiouris,Andreas Menychtas,Dimosthenis Kyriazis,Kleopatra Konstanteli,Spyridon V. Gogouvitis,Gregory Katsaros,Theodora A. Varvarigou
Issue Date:October 2013
pp. 511-524
In modern utility computing infrastructures, like grids and clouds, one of the significant actions of a service provider is to predict the resources needed by the services included in its platform in an automated fashion for service provisioning optimizati...
Content Based SLAs in Cloud Computing Environments
Found in: 2012 IEEE 5th International Conference on Cloud Computing (CLOUD)
By Nikoletta Mavrogeorgi,Spyridon Gogouvitis,Athanasios Voulodimos,Gregory Katsaros,Stefanos Koutsoutos,Dimosthenis Kiriazis,Theodora Varvarigou,Elliot K. Kolodner
Issue Date:June 2012
pp. 977-978
In this paper, we address the problem of managing SLAs in cloud computing environments. The idea is to take advantage of the content terms that concern the objects and support more efficient capabilities, such as quicker search and retrieval of the objects...
