　　Abstract: Today’s cloud platforms are facing unprecedented diverse workloads from both millions of mobile users and billions of Internet-of-Things (IoT) devices. These workloads introduces new challenges and dynamics that differ from traditional workloads. However, current cloud platforms are agnostic to the type of end-devices and are not well suited to emerging application needs. My work argues that these trends require a rethinking of current cloud architectures and focuses on the challenges of handling the dynamics introduced by these next-generation applications.

　　In this talk, I will describe two aspects of cloud design: handling demand-side dynamics from emerging cloud workloads and handling supply-side dynamics from unpredictable cloud resources. Specifically, I will first describe approaches to optimize user-perceived performance for both global workloads that exhibit spatial variations and an exemplary workload of mobile deep inference. Next, I will introduce mechanisms to effectively support running applications on transient servers---servers with unpredictable availability. Finally, I will conclude my talk with future work in cloud research to handle emerging mobile and IoT applications.
