S3 & Lambda - flexible pattern at the core of serverless applications
summary
Shows concrete S3→Lambda architectures with deployable repos and clear tradeoffs: automatic translation breaks large files into 5,000‑char chunks and supports 54 languages via Amazon Translate, transcription posts jobs to Amazon Transcribe and writes outputs to a separate bucket, state uses DynamoDB state tracker while SQS smoothing controls ingestion rate into DynamoDB with batch size and Lambda concurrency, SAM templates declare events and permissions, and an enterprise example indexes content into Elasticsearch for search.
