" summary

Migration moves a customer-facing credit-card prequalify API to AWS Lambda running Go, focusing on resiliency, zero-downtime deploys and a prefill UX. Architecture breaks logic into single-purpose functions, uses VPC/ENI-aware networking, versioning, CloudWatch logging, retries and canary deployments, and tunes timeouts, memory and GC to reduce cold starts. Load tests push beyond expected TPS. The migration yields measurable gains, claiming 70% reduction in deploy time and 90% cost saving.
