Great keynote talk this morning by Prof. John Ousterhout on his RAMCloud design and vision for low-latency data centers. Ousterhout argues that data centers going forward will focus on both scale and latency. Although most applications today are built based on high-latency assumptions, he says that new large-scale applications will be based on clouds of consciousness, which include groups of entities must have low latency access to each other's applications. Facebook friends or commuters in a local area are examples of these kinds of clouds of entities that can drive low-latency applications. Ousterhout outlined the core design principles of RAMCloud, principally driven by log-structured techniques for creating durability and efficient use of RAM. Lots of interesting ideas about where the market is headed at large-scale and what applications might drive usage in the future.
