Image Generation API

Problem Statement

QR code image generation POC is done in Java using Zxing library.

Design a way to expose this usecase for consumption.

Package the code as a executable jar

Input - Predetermined set of parameters in a String array

Output - Generated image in a pre-determined path in local node

Pros	Cons
Minimal effort to implement Existing capability built in content service, to cache images, upload to cloud and expose it as API, can be re-used	Not a generic solution. Dependency on content service

Expose the usecase to consumers directly through an API in Learning Service

Pros	Cons
Generic Solution. All consumers can directly consume the API to generate the QR code images	To avoid generation of same code multiple times, capabilities such as caching images and upload to cloud has to be built from scratch

The API currently exposed in content service for QR code image generation can consume this API to generate the QR code image.

Pros	Cons
The capabilities built in content service API to cache images and upload to cloud can be re-used	Extra API call to service the image generation request

Should the design support multiple QR code image generation per request?
In case of API, what should be the response? Image itself or the public url of the image uploaded in the cloud
Should the design support capabilities like caching images and upload to cloud?
