Primary LanguageJavaScript

nT Load Balancer

Maintainability

Load balancer for nanoTwitter, written in Node.js with Express.

Functionality

The load balancer sits in front of all our microservices (reader 1, reader 2 and write service). It redirects all POST requests to write service, and dispatches GET service to one of reader 1, reader 2 and write service using a timestamp based hash function. The hash function favors reader 1 and reader 2 over write service since we want to save the resources on write service for POST requests and database accesses.

Getting Started

To run the app:

  • cd into the repo folder
  • Run npm i to install dependencies (this requires you to have npm installed)
  • Start app by npm start and visit localhost:3000. Notice that you might need to start the read service and write service to make the app fully functional
