Cisco Systems, a multinational technology conglomerate, needed to upgrade their e-commerce platform to support over 1 million quotes and $2 billion in sales every quarter. They chose Apache Cassandra™ due to its cloud-native distributed architecture that enables better service for customers worldwide. The company uses Cassandra as a data store, Elasticsearch for search, Kafka and RabbitMq for streaming, and InfluxDB and Grafana for metrics and visualizations. Cisco's e-commerce system also benefits from unique ID generation using CAS operations and efficient data pipelines through Kafka.
