This video demonstrates how application developers can use Backstage.io on AWS to easily create containerized microservice applications with shared file systems. The presenter, Jim McVay, walks through using pre-configured templates in Backstage to rapidly deploy a scalable Node.js microservice that persists data to Amazon EFS. Key features showcased include automated infrastructure provisioning, CI/CD pipeline creation, and simplified application management through the Backstage interface. The demo highlights how this solution allows developers to focus on application logic rather than cloud infrastructure details.
