## Summary

Amazon explains how DXC built DXC OASIS, an agent system for IT operations, on Amazon Bedrock, which gives access to Anthropic Claude, Amazon Nova, Meta Llama and open-weight models through one managed interface. Bedrock Guardrails enforce content filtering, PII redaction and denied-topic policies across all models, while AWS PrivateLink keeps inference traffic inside the customer's VPC. DXC says the system has cut resolution time by 95% on average across 56 measured use cases since general availability in March 2026.
