Every payment infrastructure hits the same scaling thresholds — Lambda concurrency limits, DynamoDB partition hot spots, SQS throughput ceilings, Step Functions execution quotas. The teams that hit them unexpectedly pay in incidents and emergency rework. The teams that model them in advance pay in planned sprints.
The specific outcomes this tool produces — and the problems it prevents.
Model which AWS service limit your payment stack hits first at 2×, 5×, and 10× transaction volume. Lambda reserved concurrency, DynamoDB partition throughput, Step Functions execution rate, API Gateway TPS — each has a ceiling. Know which one you reach first.
The scaling changes are sequenced by the order you'll need them — based on your current volume and growth rate. Not a list of best practices to implement whenever, but a roadmap timed to your growth trajectory.
Some scaling work is a configuration change — a DynamoDB capacity mode switch, a Lambda concurrency limit increase. Some is an architectural change — a fan-out pattern, a CQRS separation. The roadmap separates them so sprint planning is accurate.
Export a scaling roadmap that documents current limits, projected headroom, and the planned infrastructure investment. The same document supports an engineering roadmap conversation and a due-diligence question from an investor or enterprise customer.
Structured inputs. Immediate output. No setup, no waiting, no consultant required.
Define your current architecture and volume
Select your AWS services and enter current monthly transaction volume, peak TPS, and average payload size per operation. This is the baseline for all scenario modelling.
Set growth scenarios
Define 2×, 5×, and 10× volume targets and the timeline for each. Specify whether growth is gradual or event-driven — the scaling strategy differs.
Review limit projections per service
See which AWS service limit each growth scenario approaches. Understand the headroom available before a limit is reached and the lead time needed to address it.
Evaluate architectural changes required
Review the architectural changes needed to support each growth scenario — partitioning strategy, fan-out patterns, read replicas, caching layers. Understand the implementation complexity of each.
