Additional Questions

How can you scale your implementation?

If we think this REST API will face with huge traffic a distributed system with a single or multiple load balancers could be useful for balancing all the requests to multiple servers.

How did you deploy this application?

I have used a free-to-use service which is Render.com for that deployment. I have uploaded my FLASK service with some requirements to the github and connected it to render.com. Then started the Flask service with gunicorn on the cloud.

How can you improve this process and make it easy to maintain?

I can use a serverless cloud service for deployment and use storage services to store string-hash pairs.
