Until now, most research on cloud service placement has focused on static pricing scenarios, where cloud providers offer fixed prices for their resources. ...
However, with the recent trend of dynamic pricing of cloud resources, where the price of a compute resource can vary depending on the free capacity and load of the provider, new placement algorithms are ...
CONCLUDING REMARKS In this contribution, we study a series of algorithms for cost-optimal cloud service deployment under dynamic pricing schemes. ...
