This project is a Spring Boot microservices-based pipeline for uploading and processing images.
It consists of two services: a ImageUploadApi for session management & uploads, and an ImageProcessingApi for image processing.

• Port: 8080
• Accepts image upload requests from clients.
• Enforces:
  • Maximum 10 images per session
  • Rate limit: 10 requests/minute per IP
• Stores uploaded images temporarily on disk:
  /tmp/uploads/{sessionId}/{imageId}.jpg
• Maintains session & image IDs in Redis.
• Sends the uploaded image to the Internal API for processing.

• Port: 8081

• Processes the image sent by Upload API:

  • Resizes to ≤ 720x1280px
  • Compresses as JPEG (90% quality)

• Saves the processed image at the given destinationFilePath.
