Start with Google Cloud Functions (GCP-native events)
If your backend workloads run on AWS and you need event-driven processing, scheduled jobs, or API backends without managing servers, AWS Lambda is the natural default. Lambda's integration with SQS, SNS, EventBridge, S3, and API Gateway creates a complete event-driven architecture within a single cloud. The main watch-out is that Lambda isn't free at scale — and the 15-minute execution limit and memory constraints mean some workloads need Step Functions or ECS instead. For teams already on AWS, the integration coherence typically justifies Lambda over a standalone alternative.
