Nutonian developed a SaaS application that simplifies the creation of analytical models for business users without requiring data science expertise. The application architecture involves Node.js for managing application logic and MongoDB for data storage, allowing for efficient communication with the core engine. Nutonian prioritizes ease of deployment across multiple platforms and has created utilities for controlling cloud resources using Node.js.

- 2. About Nutonian • Built the first, best and only application that automatically builds analytical models that can be translated into English. • Enables business users to understand and take action without hiring data scientists/consultants. • SaaS application + deployable on Linux, Windows and Mac OS. 12/4/2014 | 2
- 3. About Nutonian • Example: What drives my marketing leads, and how do I increase it? 12/4/2014 | 3
- 4. Product Architecture 12/4/2014 | 4 Browser Application Logic (Node.js) Database (MongoDB) Core Engine (C++) Search Servers (C++) JSON/HTTP Proprietary format JSON/HTTP Firewall/Load Balancer
- 5. Core Engine • Uses symbolic regression to find best equation to fit data – Very computation intensive, but easily parallelizable • Started off as desktop program • First attempt at SaaS – linked web server with core engine • Tedious to implement things like a document store 12/4/2014 | 5
- 6. Enter Node.js • Significant amount of application logic unrelated to core engine – Doc store, Object store – MIME Parsing • Communicates with engine via JSON over HTTP – Core engine already had web server • Handles all client requests – Proxies through requests to core engine 12/4/2014 | 6
- 7. Application Logic • Core engine provides low-level endpoints • Multi-step processes encapsulated as single endpoint in Node.js – Initially implemented in client Javascript – Maintaining state was challenging – Needed to move logic to backend • Quicker to implement than in C++ – IMO; depends on who you ask 12/4/2014 | 7
- 8. Interesting Features • Core engine and Node.js have bi-directional communication – Engine persists state to Mongo via Node.js – Use Express, Request modules – Had to debug interesting deadlocks • Ease of deployment has always been a priority – Single binary that includes backend JS code + modules, launches Node.js on startup – Multi-platform – runs on Windows, Linux and Mac OS – Runs in local-mode as well (without Mongo) 12/4/2014 | 8
- 9. Skynet • Initial use of Node.js got us Javascript- happy • Wrote a collection of command line utilities – Skynet – Control Amazon EC2 machines – provision clusters, start/stop – Save/restore state of system • Node.js is our cross-platform scripting system of choice 12/4/2014 | 9
