Abstract: Cloud computing has emerged as a crucial platform for business and personal applications. However, the management of the infrastructure behind the cloud (i.e. data centers) is far from mature and there are many algorithmic challenges that remain, such as data management, capacity management and energy management. In this talk I focus on our recent work on two such challenges: dynamic provisioning and geographical load balancing. In both contexts I will present our new algorithms, which provide significantly improved performance guarantees when compared with the "standard" approaches using Receding Horizon Control. Additionally, I will present a case study of our algorithms for cost-effective geographical load balancing.
