SmartNews has evolved its use of AWS over time from a monolithic application to microservices as its scale increased. It now uses over 300 EC2 instances, 80 ELBs, and many other AWS services. Configuration management has moved from pull-style deploys to using tools like CodeDeploy, Auto Scaling Groups, and infrastructure as code. Future plans include further containerization and event aggregation
