USA Research Interests
I am interested in a wide variety of topics in infrastructure research areas, including Cloud Computing, Virtualization and Networking. These research interests are reflected in the following projects we have done and/or we are pursuing. Recent Projects
1. Cloud Computing: Computing Cloud, such as Amazon EC2, presents strong value propositions to our large enterprise clients. Many enterprises want to exploit the large on-demand computation capacity and pay only for what they use (rent vs. buy). Inspired by Google's MapReduce technology, we are building an infrastructure to help parallelize large-scale data-intensive enterprise applications in a Cloud environment. 2. Virtualization 2.0: Virtualization 1.0, such as VMWare ESX, Citrix Xen or Microsoft Hyper-V, is commodity and main-stream today. As a decoupling layer between the infrastructure and the application, virtualization is moving beyond server consolidation. As an example, it enabled Cloud Computing mentioned above, i.e., a dynamic on-demand infrastructure. We are exploring other usages enabled by virtualization, such as package software release (virtual appliances), application development and infrastructure security. 3. Network virtualization: Even though server virtualization is advancing at a face pace, network virtualization is still at its infancy. We are exploring what would be enabled when routers and wires are both virtualized. Currently, we are building a remote network labs, where the wire is virtualized (an Internet tunnel instead of a physical wire). Wire virtualization allows us to mobilize equipment so that we can leverage test equipment from project to project and build test labs much more quickly and cost effectively.
