Google Cloud Functions
Pros
- + 2 million free invocations per month, permanently, per billing account

- + 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

Cons
