Practical Test

Install the server

npm i

Install artillery

npm i artillery -g

Read the server code and understand its function

Start the server

node index.js

Run the artillery testlow to see how the server behaves in low traffic

artillery run testlow.yml

Run the artillery testhigh to see how the server behaves in high traffic

artillery run testhigh.yml

As you can see in high traffic the server is not performing very well, not only do requests take a very long time to return a response some requests are not even being processed as the server returns errors

Edit the Answers.txt file with answeres to the following questions:

1. what is the main issue that is causing the server to return errors?
2. how will you refactor the server to make sure it will process all requests in each of the following scenarios:
   • you have no additional resources other than the original server (assume the server spec is the same as your laptop)
   • there is no time limit for the server response
   • you have any additional resources you want to make the system run as fast and handle as many requests as possible
3. choose one of the solutions you proposed and start refactoring (start with pseudo code and only then start to flesh it out)

Zip the code and send it to [email protected]

Good luck!
