Getting to know the sample app

“

- [Instructor] The sample app we'll be using in this course consists of a front end implemented in Node.js using Express, and this front end sends requests to the backend services using a service gateway written in Python using Flask. This service gateway is set up to randomly forward requests to two backend services called Service Green and Service Blue. Both services provide the same functionality, but Service Green is, again, using Python and Flask, while Service Blue uses Node and Express. This blue-green naming isn't chosen randomly. It stems from a common practice called Blue/Green Deployment. Look it up if you want to learn more. For persistence, both services are using MongoDB. All right, now let's set this up and see what this application is actually doing.
