Who is AWS API Gateway best for?

Best use cases for AWS API Gateway

• AWS-native applications where Lambda functions, HTTP backends, or AWS services need a managed API frontend with automatic scaling, IAM-based auth, and zero infrastructure management.
• Teams building serverless APIs where AWS API Gateway and Lambda together provide a fully managed API backend that scales from zero to millions of requests without capacity planning.
• Organizations that want usage plans and API keys for controlled external API access — metering requests per consumer, setting rate limits, and tracking usage per key without custom rate-limiting infrastructure.

Who should avoid AWS API Gateway?

• You must remain portable across clouds/clusters with a consistent policy model
• You expect very high request volume and haven’t modeled per-call pricing and growth
• You need deep enterprise governance processes across many producer teams

Upgrade triggers for AWS API Gateway

• Per-request cost becomes material and you need architectural changes (caching, consolidation)
• You need consistent policy templates across many teams and environments
• You need an enterprise API program model (portals, keys, quotas, governance workflows)
