Register now for "Using Application-Level Data to Solve System-Level Problems in First-Party Cloud Services", a free IMOBILE ACM Chapter Webinar to be presented on Friday, 19 August 2022 at 11 am IST (5:30 am UTC) by Ranjita Bhagwan, Senior Principal Researcher at Microsoft Research India (IMOBILE is the India Chapter of ACM SIGMOBILE).

Duration: 1 hour

Abstract: Today, large Cloud providers such as AWS, Microsoft and Google also run some of the largest Cloud applications, such as Amazon, Exchange Online and Google Search. Such large “first-party” applications—where both the application and the infrastructure are owned and operated by the same entity—use a significant amount of resources of the Cloud. Additionally, such applications also generate several petabytes of telemetry each day. This setting provides the unique advantage of visibility into and control over both the application and the infrastructure. In this talk, I will use two examples to demonstrate how we leverage the first-party setting by using application-level data to solve system-level problems. First, I will describe a cross-layer optimization framework for efficient WAN capacity provisioning that uniquely combines application-level signals (e.g., deadlines) with network-level information (e.g., failure history). Next, I will describe how we use application-level, semantically-meaningful query-based signals to organize and enable effective navigation of petabyte-scale data lakes.
