AWS Lambda is rated higher (4.1 vs 3.9). Google Cloud Functions is GCP's serverless compute. HTTP-triggered or event-driven. 2M free invocations/month. Node.js, Python, Go, Java, Ruby, PHP, and .NET supported. Deep integration with Firebase. AWS Lambda is the original FaaS service — run code without servers. Supports 15+ runtimes, 1M free requests/month, and integrates deeply with 200+ AWS services. Triggered by S3, DynamoDB, API Gateway, and more.

Google Cloud Functions
Pros
- + 2 million free invocations per month, permanently, per billing account
- + Published 99.95% uptime SLA with 10/25/50% financial credits
- + 2nd gen on Cloud Run infrastructure: concurrency, Eventarc triggers, traffic splitting, GPU access
- + First-class Firebase, Pub/Sub, Cloud Storage, and Secret Manager integration
Cons
- - GCP lock-in: events, IAM, and deployment are Google Cloud objects
- - Gen 1 / gen 2 split means two pricing models and two capability levels in one product
- - Costs scale with abuse and bugs — every failed invocation is billed, no per-function spend cap
- - Container image storage (Artifact Registry) bills separately even within the free tier
AWS Lambda
Pros
- + Zero idle cost with a free tier that covers small products: 1M requests and 400,000 GB-seconds monthly
- + Graviton pricing at $0.0000133334 per GB-second undercuts x86 by roughly 20%
- + Automatic multi-AZ scaling with a 99.95% per-region SLA and no capacity planning
- + Deep event integration across AWS services, with three form factors (Event/Web Functions, MicroVMs)
Cons
- - Per-request and GB-second pricing gets expensive against committed compute at steady high utilization
- - Cold starts — hundreds of milliseconds to seconds depending on runtime — with provisioned concurrency as an extra meter
- - 15-minute execution limit and payload caps make it wrong for long-running batch work
- - AWS-specific event plumbing creates real lock-in; distributed event chains are hard to debug
