A serverless reference architecture for real-time parallel file processing using AWS Lambda, S3, SQS, and Amazon Comprehend.
Lambda-refarch-fileprocessing is a serverless reference architecture designed for real-time, event-driven file processing on AWS. It demonstrates a parallel data processing pattern ideal for workloads requiring multiple data derivatives from a single object, such as converting Markdown files to HTML and performing sentiment analysis simultaneously.
AWS architects and developers building scalable, event-driven file processing pipelines that require concurrent, independent workflows from a single file upload. It is particularly relevant for those needing to implement fault-tolerant, observable systems using managed AWS services.
Developers choose this project as a production-ready blueprint that emphasizes loose coupling, fault tolerance, and operational excellence through built-in error handling, monitoring, and automatic scaling using serverless AWS services, reducing the need to design these patterns from scratch.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Uses S3 events and SQS queues to trigger independent Lambda functions for conversion and sentiment analysis simultaneously, enabling scalable parallel workflows as demonstrated in the architectural diagram.
Implements dead-letter queues (DLQs) and CloudWatch alarms for failed messages, with a comprehensive dashboard for monitoring, ensuring fault tolerance and operational excellence.
Leverages AWS Lambda, S3, SNS, and DynamoDB for automatic scaling and cost efficiency, as described in the key features for event-driven file processing.
Includes a CloudWatch dashboard with metrics for function invocations, error rates, and queue lengths, providing real-time insights into system health.
Heavily dependent on AWS-specific services like SNS, SQS, Comprehend, and DynamoDB, making migration to other clouds difficult and limiting portability.
Requires AWS SAM CLI version 0.41.0 or higher and Docker, with specific setup steps that can be cumbersome, as noted in the pre-requisites and build instructions.
Focused on Markdown to HTML conversion and sentiment analysis; adapting to other file types or processing logic requires significant code changes beyond the provided template.
