Abstract: Google has deployed one of the largest network infrastructures worldwide connecting tens of data centers to billions of users worldwide with a large diversity of workloads (e.g. youtube, search, maps, photos, mobile). A lot of the design principles in the past 20 years was based on Moore’s law. If whether or not Moore’s law has ended is debatable, the fact it will end soon is not and this will impact the way we are designing compute and storage infrastructures. We present the GOOGLE network infrastructure, explain how the end of Moore’s law will impact our design and discuss what the research challenges are for our data centers and networks. We will focus on how telemetry at scale can help us manage always increasing availability in such a massive and growing infrastructure.
Bio: Christophe Diot received a Ph.D. degree in Computer Science from INP Grenoble in 1991. Diot pioneered diffserv, single source multicast, epidemic communication, peer-to-peer online games, and most importantly Internet measurements. After INRIA, Diot spent his career in industry, building R&D labs at Sprint, INTEL, Technicolor. He helped launch Safran Analytics as their CTO before joining GOOGLE in june 2018 as principal engineer in the Network Architecture group. At GOOGLE, Diot deals with telemetry at scale in cloud infrastructure. Diot has around 40 patents and more than 300 publications in major conferences and journals. He is an ACM fellow.
