 +This system serves as a foundational framework for performing model inference triggered by events, such as API calls or streaming data ingestion from Kinesis. With built-in support for environment configuration, retry logic, and cloud-native monitoring through AWS CloudWatch, the Lambda Model Inference module is optimized for reliability and operational transparency. It seamlessly fits into modern CI/CD workflows and MLOps pipelines, enabling rapid deployment and iteration cycles. 
 + 
 +Additionally, its modular design allows for integration with other AWS services such as DynamoDB for result persistence, API Gateway for RESTful interfaces, and SageMaker for pre-trained models. This makes it a flexible and production-ready choice for teams seeking to operationalize machine learning in real-time, event-driven ecosystems.
