Abstract or description

With the unprecedented demands for cloud computing services recently, cloud service providers have built
several geo-distributed cloud data centers to meet these increasing demands. On peak times, these cloud
data centers receive unpredictable amount of workload that might go beyond their capacity. So, cloud data
centers need to be ready to work with their full capacity most of the time. The aforementioned objective
is hard to be guaranteed given the possible incidents that may cause cloud services interruption such as
power outages, security breaches, natural disasters, etc. Since cloud providers are facing serious threats
to the continuation of their services o�ering which will cause a serious decrease in their revenues, they
must have proper strategies for handling such incidents. While a rich volume of recent research works
focused on optimizing cloud data centers operations that reduce its operational cost (OPEX), there exists
no prior work, to the best of our knowledge, that considers optimizing cloud data center under serious
incidents constraints in order for the data centers to maximize their revenue from the services they o�er
while respecting the service level agreement (SLA) with their customers. In this study, we model this
optimization problem using mixed integer-linear programming. To evaluate the proposed model and the
impact of di�erent parameters on its performance, several simulation experiments are conducted.
