CHAI Platform Infrastructure and Deployment Reference Guide

The CHAI Platform Infrastructure and Deployment Reference Guide serves as a comprehensive resource for deploying the CHAI platform on Amazon Web Services (AWS). It details the architecture, high availability, disaster recovery strategies, external integrations, and compliance with the EU Digital Operational Resilience Act (DORA). The guide outlines the deployment architecture, including three primary topologies: Single EC2, Multi-AZ Active-Standby, and Full HA with Blue/Green deployments, each catering to different organizational needs. It provides specific configuration notes for AWS services utilized, such as EC2, Application Load Balancer, and EFS. Additionally, the document includes operational responsibilities for both CloudHedge and customers, ensuring clarity in roles regarding updates, security patches, and incident management. This reference is designed to be self-sufficient, providing all necessary information for infrastructure engineers, security architects, and compliance officers involved in the deployment and maintenance of the CHAI platform.
