DXC OASIS on Amazon Bedrock cuts resolution time 95%

DXC Technology's starting point is a specific failure mode: an autonomous agent holding more authority than its task requires, with nothing in the architecture to stop it. The company's answer was to split the problem in two. Amazon Bedrock supplies a governed gateway to models—Claude, Nova, Llama, and open-weight families—with Guardrails, PrivateLink, and serverless scaling applied uniformly. On top sits DXC's own harness, carrying 60 years of runbooks, escalation logic, and ITSM data, plus the policy enforcement and human-oversight gates that Bedrock does not provide.

The division of labor is deliberate. DXC's team lists four design goals—resilience, flexibility, regulatory sovereignty, and safety by design—and argues no single control delivers any of them. Serverless infrastructure, model-layer guardrails, private networking, and approval gates compound into defense in depth. The harness also owns assurance: OpenTelemetry traces for every action, each with a unique execution ID, so auditability comes from DXC's layer rather than the agent's own account of what it did.

DXC began the build as a prototype in early 2025, reached general availability in March 2026, and is scaling toward 130 customer environments on Amazon EKS with per-tenant namespaces. Beyond the 95% average reduction in resolution time, diagnostic accuracy is 92% or better against senior engineer judgment. The company is now evaluating Amazon Bedrock AgentCore alongside its current orchestration layer, which suggests the substrate-harness boundary may be redrawn as AWS's own agent tooling matures.
