AIP-C01 23/36: Resilient FM APIs and Model Routing

Resilient FM APIs and Model Routing explained for the AWS Certified Generative AI Developer Professional exam: make FM calls resilient with AWS SDK retries (exponential backoff with jitter, adaptive mode for rate limiting), API Gateway throttling, fallbacks to other models or Regions, and AWS X-Ray tracing; route requests statically by configuration, dynamically by content with Step Functions, or with Bedrock intelligent prompt routing within a model family. Resilient FM APIs and Model Routing is in Domain 2, Implementation and Integration, which is 26% of the AIP-C01 exam. This exam-focused lesson is for developers building production generative AI applications on AWS preparing for the certification. What you will learn: • Retry modes in the AWS SDK • Rate limiting with API Gateway • Fallbacks and graceful degradation • Tracing with AWS X-Ray • Static, dynamic and intelligent routing • Exam traps and self-check questions CHAPTERS 00:00 Resilient FM APIs and model routing for the AIP-C01 exam 00:33 Retry modes in the AWS SDK 01:05 Rate limiting with API Gateway 01:30 Fallbacks and graceful degradation 01:58 Tracing with AWS X-Ray 02:27 Static, dynamic and intelligent routing 02:58 Exam traps for resilience and routing 03:27 Self-check questions AIP-C01 full course: video 23 of 36, in blueprint order (Domain 1 to Domain 5).
