In essence, this application was centered around inheriting Getsy's legacy codebase and then extending the capabilities of the database and server layer to support production-level traffic while maintaining its service-oriented architecture. The task entitled implementing techniques such as indexing, compression, clustering, horizontal scaling, and caching. To learn more about the journey, feel free to reach out to me at [email protected].

After horizontally scaling the service on 4 AWS EC2 t2.micro instances and utilizing round robin load balancing with content caching on my NGINX proxy server, I was able to handle 10,000 requests per second with a 0.0% error rate and an average latency of 62 ms.

This is in comparison to a 45.3% error rate and an average latency of 3727 ms before all the optimizations.

In conclusion:

This equates to...

Open up the terminal and from within the root directory, run the following commands:

npm install
npm run csv

The "npm run csv" script creates a CSV file in the root directory named "entries.csv".

Navigate to the database directory and import the schema into Postgres by running the command:

psql postgres < schema.sql

And then the seeding script:

npm run seed

Go back to the root diretory and run these scripts to start the server and serve the static files:

npm run build
npm start
