Choose Azure OpenAI when
Microsoft Entra ID and enterprise policy patterns are first-class.
Choose Amazon Bedrock when
IAM-centric; integrates with AWS Organizations and SSO patterns.
Decision axes: Model focus · Identity & enterprise · Private networking · Ops & monitoring
Overview
Azure OpenAI and Amazon Bedrock are enterprise routes to frontier models—GPT-family on Azure versus a broader model catalog on AWS (including Anthropic and others). The decision is usually cloud estate, identity, data gravity, and procurement—not a single benchmark.
