Abstract:   This paper explores the impact of future trends on Big Data and Exascale Cloud Computing systems. This paper explores: (i) next-generation processors using 14 nm CMOS, (ii) next-generation photonic integrated circuit technologies, and (iii) a next-generation 'lean' Internet router. The new processors offer higher performance and a large embedded memory (eRAM) on one integrated-circuit, while consuming less power. Photonics integrated circuits will lower size and energy requirements of routers significantly. The lean router supports deterministic TDM-based virtual circuit-switching in an IP network,which will lower buffer sizes and cloud latencies significantly. The traffic flows between data-centers are aggregated onto the optical connections, to achieve ultra-low latencies with 95-100% link utilizations and improved energy-efficiencies. Analysis indicates that the use of both architectural innovations and photonics integration will support the cloud communications needed for Exascale performance. Using 2015 technology, a small cloud computing system could support about 62 PF/sec, while consuming 13.1 MW for computation and 1.484 MW for cloud communications.
