Seamless Customer Experience at Walmart Stores Powered by Kubernetes@Edge - Maneesh Vittolia, Principal Architect & Sriram Komma, Principal Product Owner, Walmart

At Walmart, while major application software can and does operate in the cloud, stores or any client edge compute cannot avoid the intermittent network events that can create less than ideal availability and performance of the software during those times.  This can lead to poor customer experience and/or failed transactions during checkout. Because of Walmart's scale of serving around 265 million customer every week, the comnbined effect on customer experience as well as the loss of revenue is pretty huge.

To overcome the issue between Stores and cloud, Walmart is building and rolling out the next generation of Point of Sale (POS) systems on highly resource constraint edge computing environment using modern service mesh based technologies designed to allow maximum business flexibility, extreme performance and rapid deployment and powered by Kubernetes.

Serverless Platform for Large Scale Mini-Apps: From Knative to Production - Yitao Dong & Ke Wang, Ant Financial

Ke Wang and Yitao Dong from Ant Financial share the key workloads they are building with serverless and how they address pain points in production by expanding Knative. They introduce technical details of adopting Knative with secure container runtime and reinventing Knative control/data plane, which largely saves deployment and operation efforts to enable serverless in Kubernetes clusters. The discussion will also cover a quick demo to illustrate improved serverless app lifecycle management, 0-M-N-0 autoscaling performance and operation workflow.

Using FoundationDB and the FDB Record Layer to Build CloudKit - Scott Gray, Apple

This talk is about the features of FoundationDB and the Record Layer that help build CloudKit, Apple’s cloud storage system for structured data. Scott Gray, a software engineer at Apple focuses on three key areas where FoundationDB and the Record Layer have unlocked large benefits for CloudKit. First, FoundationDB’s arbitrary multi-key ACID transactions have allowed implement advanced secondary indexing at scale, including our recently-developed transactional full-text search system.
