Alfred

Alfred is a robust framework developed in C++20, designed to manage and assess environmental scenarios using the Chesapeake Assessment Scenario Tool (CAST). This tool helps in estimating nitrogen, phosphorus, and sediment loads by applying best management practices (BMPs) over specified geographic areas.

Features

• Messaging with RabbitMQ: Utilizes AMQP protocol to manage communications between clients and the framework.
• Data sharing with Redis: Shares scenario information efficiently using Redis.
• Storage with AWS S3: Manages the storage and retrieval of scenario files using AWS S3, ensuring scalability and performance.
• Comprehensive Library Support: Built with essential C++ libraries like Boost, cURLpp, hiredis, redis++, SimpleAmqpClient, and aws-cpp-sdk-core.
