About the Project:

The Customer’s solution has a few services that exist outside the primary monolith, which provide additional functionality to Customer’s core product - the world's fastest growing learning management system.

  • a document viewing and annotation service. This is made up of a couple services, a Node app and a conversion service (knight rider) written in Java. Backed by S3 and DynamoDB. It also uses SQS and has a small amount of Scala.
  • LTI applications using Ruby and Rails. They are deployed on our platform infrastructure and leverage Postgres, ElastiCache, S3, etc.
  • a learning content package manager. This service is made up of a 3rd party service written in Java/JavaScript/MySQL. Hosted with EC2 and RDS. There's also a wrapper written in rails/js/postgres.


Current Project Stage:
