Imagine being tasked with collecting, analyzing, and securing data from hundreds of sources around the world, in multiple cloud and on-premises environments. Toyota Motor North America, along with Booz Allen Hamilton, has created a secure, cloud-native solution to analyze billions of messages per day using AWS Key Management Service (AWS KMS). We discuss how AWS KMS with AWS native services provides granular access and secures corporate assets with data segregation using AWS KMS encryption. Toyota uses AWS Glue, Amazon Athena, and Amazon SageMaker to generate actionable intelligence in its corporate IT and vehicle telematics environments to solve its business and analytics challenges.
