What is the technology stack of Learning Navigator?

  • NLC embraces open-source technologies in realizing the Navigator and at a broad-level following are the guiding design principles used:
    • Microservices architecture for better scale
    • RESTful API with JSON responses to access core features
    • Consistent API design for ease of development
    • Open-source technologies at all layers of solution
    • Queuing over message bus for communication across microservices
    • Localization support
    • Scalable with minimum footprint
    • Deploy not tied to custom infrastructure
  • Consequently, the choice of technology reflects the same:
    • Ubuntu Linux OS is the choice of development and deploy environment
    • Java-based microservices implementation
    • Postgres database as primary datastore
    • ElasticSearch extensions for search engine
    • Postgres based datastore for analytics data
    • Kafka as a message bus for data relay across microservices
    • AWS hosting environment, leverage at infra-level and not custom services
    • Github for source code management
    • Atlassian Bamboo for CI/CD
    • Atlassian Jira for product backlog, releases and bug tracking
