Why people consider alternatives to AWS Lambda
Lambda runs your code without servers to manage. Upload a function, configure a trigger, and AWS handles scaling, patching, and availability. Here are the real cost and limitation gotchas that push teams to look elsewhere:
- •Duration billing rounds up to the nearest millisecond, but memory billing is per-GB-second at allocated memory (not used memory). Allocating 1 GB but using 200 MB still bills for 1 GB, right-sizing memory is critical
- •Provisioned Concurrency: eliminates cold starts but charges $0.0000041667/GB-second even when idle. Provisioning 100 instances at 512 MB costs ~$54/month whether they handle traffic or not
- •Data transfer out: Lambda itself is cheap, but responses that cross AZ boundaries or leave AWS incur standard EC2 data transfer charges ($0.01-0.09/GB). High-traffic APIs serving large payloads can have transfer costs exceed compute costs
- •VPC-attached Lambda: connecting to RDS or ElastiCache inside a VPC adds ~200-500ms cold start overhead and creates ENI resources. VPC Lambda also requires NAT Gateway ($32/month + $0.045/GB) for outbound internet access
The 8 alternatives below cover the same core job (serverless) with different trade-offs. Ranked by real-signal score: G2 and Capterra ratings, media mentions, and editor review.
