How Verizon Media implemented push notification using Amazon DynamoDB

Verizon Media had to create a better, stronger, and faster push notification system to serve the requirements of iconic Verizon brands, fulfill push notification completion time of 27 million devices in under three minutes, and consistently show the push “toast” on all users’ lock screens. Verizon decided to use Amazon DynamoDB and other AWS services such as Amazon ElastiCache and Amazon SQS in conjunction with its own Vespa search engine to power all the use cases of its brands. It also uses Kubernetes to orchestrate microservices across many Amazon EC2 instances.
