When to pick Azure OpenAI Service
Best for
- Existing AWS / GCP / Azure customers — same IAM, same VPC, same billing.
- Regulated workloads requiring the hyperscaler's compliance frameworks.
- Multi-region production deployments tightly coupled to other cloud services.
Avoid for
- Cost-sensitive workloads — hyperscaler markup over first-party is real.
- Anyone who doesn't already need the surrounding cloud platform.
