This project uses services from three Cloud Service Providers (AWS, GCP and Azure) and it is an entirely serverless project.
The website (html, css and javascript) is hosted on AWS S3 and the uploaded images are stored on S3.
AWS Lambda functions are used to create S3 Pre-Signed URLs for the image upload and triggered by S3 to send the image for analysis.
The image analysis is performed by GCP Vision and the analysis results are stored in Azure Cosmos DB.
