Implementing resilience patterns with Amazon Bedrock and LLM gateway | Amazon Web Services
Implementing resilience patterns for large language model (LLM) inference is critical as generative AI workloads move from experimentation to production at scale. With LLM powered apps now in production, organizations need ways to keep LLM inference highly available, responsive, and cost-effective at scale. Existing resilience best practices like static stability and implementing backoffs and retries still apply. However, generative AI introduces new considerations including model availability, rapidly changing quotas, token limits across multiple providers, and maintaining consistency with newly released models. Amazon Bedrock provides fully managed foundation models with built-in resilience features like cross-Region inference.
When designing inference for production, four dimensions typically guide architectural decisions: availability, response time, cost, and throughput. Availability refers to sustaining inference during model, Region, or provider disruptions. Response time covers how quickly the user receives output, often measured as Time to First Token (TTFT) and Time to Last Token (TTLT)....
