AWS Bedrock Best Practices Advanced

SECURITY:
  [ ] IAM roles scoped to specific models (bedrock:InvokeModel)
  [ ] VPC endpoint for private Bedrock access
  [ ] CloudTrail logging for all API calls
  [ ] Guardrails configured for content safety
  [ ] Input validation before sending to model
  [ ] Output sanitization before returning to users

COST MANAGEMENT:
  [ ] Token budgets per application/user
  [ ] CloudWatch metrics for token usage tracking
  [ ] Smaller models for simple tasks (Haiku vs Sonnet)
  [ ] Caching for repeated/similar queries
  [ ] Batch API for offline processing (50% savings)

RELIABILITY:
  [ ] Retry logic with exponential backoff
  [ ] Circuit breaker for model endpoint failures
  [ ] Fallback to alternative model on errors
  [ ] Request timeout configuration
  [ ] Rate limiting in API Gateway

MONITORING:
  [ ] CloudWatch dashboards for latency, throughput, errors
  [ ] Custom metrics for response quality
  [ ] Logging prompts and responses (with PII redaction)
  [ ] Alert on token budget overruns
  [ ] Track model invocation costs by application
