Under the hood
Voila runs entirely on Amazon Web Services.
- Amazon Bedrock (Titan multimodal embeddings) powers visual similarity search and background removal.
- Amazon S3 Vectors indexes item photos; S3 stores the images.
- Amazon Cognito handles sign-in; DynamoDB, API Gateway and Lambda run the backend.
