Project MVP - Design Decisions - a.k.a. Why?

This is a list of design decisions to support the MVP of our product.

Maintainability

• We prioritize productivity and time to market, so we plan to use Rails since the team is familiar with the technology even if it might be suboptimal.
• Skip automated tests because of lack of time and money for the MVP

Scalability

• We expect from 500-2000 active users using our systems daily. This should be easily achievable with a modest deployment in Google Cloud and Kubernetes.

Node.js Design Decisions - a.k.a. Why?

This is a list of design decisions to support version 0.2 of the Node.js library

Maintainability

• We want to make it simple to work with asyncronous IO
• No function should direct perform I/O. Use callbacks instead
• Have built in support for important protocols (TCP, DNS, HTTP) and support many HTTP features (chunked requests, keep alive, comet etc.)
• The API should be both familiar to client-side JS programmers and old school UNIX hackers.
• Be platform / operating-system independent
• Reuse solid platforms (Google V8) and minimize dependencies (python only)
