Best use cases for AWS Lambda

  • AWS-first teams building event-driven systems with managed triggers
  • Backends where integrations reduce plumbing work (events, queues, storage)
  • Workloads with bursty traffic patterns that benefit from elasticity
  • Organizations with existing AWS governance/IAM standards

Who should avoid AWS Lambda?

  • Edge latency is the product (middleware/personalization) and tail latency is unacceptable
  • You need minimal cloud coupling and want portability as a primary requirement
  • Your workload is sustained, egress-heavy, and better suited to always-on compute

Upgrade triggers for AWS Lambda

  • Tail latency and cold start impact become visible to users or SLAs
  • Concurrency/throttling issues appear during bursts and require capacity controls
  • Spend spikes require workload math and architectural changes (caching, batching)
