Tech

Erospace uses a number of open source frameworks and AWS services to work properly:

• AngularJS - HTML enhanced for web apps!
• Twitter Bootstrap - great UI boilerplate for modern web apps
• node.js - evented I/O for the backend
• Express - fast node.js network app framework to act as middleware

And of course Erospace itself is based on most AWS services.

Cloud IaaS

AWS services used for this solution:

• Lambda - serverless containers!
• DynamoDB - NoSQL Database
• API Gateway - Service layer
• Cloudwatch - Dashboards and Alarms
• SNS - Notification service

And of course Erospace uses a lot more that can be understood from the Architecture Diagram for the entire landscape.
