Pricing for AWS Lambda
How pricing changes as you scale: upgrade triggers, cost cliffs, and plan structure (not a live price list).

Pricing behavior (not a price list)
These points describe when users typically pay more and what usage patterns trigger upgrades.
Actions that trigger upgrades
- 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)
What gets expensive first
- Retries, timeouts, and partial failures require idempotency design
- Observability is mandatory to debug distributed failures and tail latency
- Cross-service networking and egress costs can dominate at scale
- Lock-in increases with AWS-native triggers and event topology
Plans and variants (structural only)
Grouped by type to show structure, not to rank or recommend SKUs.
Plans
- On-demand functions - default baseline - Pay-per-use works best for spiky traffic and event triggers; steady traffic can create cost cliffs.
- Provisioned capacity / warm capacity controls - latency guardrail - Use when cold starts become user-visible for synchronous endpoints.
- Official site/pricing: https://aws.amazon.com/lambda/
Enterprise
- Enterprise governance - IAM + org rollout - The real plan is policy: permissions, secrets, audit expectations, and deploy workflow.
Next step: constraints + what breaks first
Pricing tells you the cost cliffs; constraints tell you what forces a redesign.
