Common mistakes with serverless architecture in customer journeys often include underestimating cold start latency, which can degrade user experience, especially during initial interactions with services. Many teams also fall into the trap of deep vendor lock-in by excessively leveraging proprietary services without abstraction, making future migrations challenging and costly. Another significant issue is complex debugging and monitoring across highly distributed functions, requiring robust observability tools to trace end-to-end customer flows effectively. Furthermore, mishandling stateless function design by not properly externalizing state can lead to architectural fragility and data inconsistencies. Lastly, neglecting proper cost optimization and function-level security can result in unexpected bills or critical vulnerabilities, ultimately impacting the reliability and trust of the customer journey.
