How Intuit built an agentic disaster recovery assistant with Amazon Bedrock

This article describes how Intuit built EWOK Agent, an AI-powered disaster recovery assistant using Amazon Bedrock that automates failover orchestration for large-scale distributed systems.

• EWOK Agent encodes failover knowledge as typed skills that compile into tool specifications for foundation models
• Amazon Bedrock Converse API with guardrails enables safe model selection and reasoning without hardcoding decision trees
• Bounded agentic loop keeps models deciding what to do while deterministic executors handle how actions are performed
• Security controls include credential blinding, prompt injection defense, and least-privilege IAM scoping
• Engineers stay in supervisory role approving critical actions while agent automates orchestration across compute, databases, caches, and traffic
• Reduces failover coordination from hours to 20 minutes for supported workloads across millions of users

The pattern separates model reasoning from deterministic execution, enabling production-grade agents that take real actions while maintaining auditability and human oversight.
