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.

Role of Spark in transforming eBay’s Enterprise Data Platform

eBay has one of the most mature Enterprise Data Platform’s in the industry with over 200PBs of data stored in Hadoop and Teradata Warehouses. On average 30 TB of transactional and behavioral data is extracted on a daily basis and thousands of metrics are computed, analyzed and monitored for decision making and detecting anomalies. eBay has embarked on an ambitious project to transform the batch oriented ETL processes which could take 24 to 48 hour for metric computation to near real time infrastructure based on Kafka for messaging, Spark Streaming for stream processing and Spark SQL for data preparation.

Needle in the Haystack—User Behavior Anomaly Detection for Information Security

Salesforce recently invented and deployed a real-time, scalable, terabyte data-level and low false positive personalized anomaly detection system. Anomaly detection on user in-app behavior at terabyte-data scale is extremely challenging because traditional techniques like clustering methods suffer serious production performance issues.
