Demand study

The evidence behind DevCloud’s coverage target. Sampled 2026-09-05; re-derive with python3 scripts/demand_rank.py.

What this measures

DevCloud has no usage telemetry, so this page does not measure what its users ask for. It measures revealed demand: how many of three independent projects have already built each AWS service DevCloud does not register. Each serves a population DevCloud names as its own, and each only adds a service when somebody asks.

Source	What it is	Services	Unmatched names
moto	Python AWS mocking library: boto3 developers running tests	163	0
LocalStack	Local AWS emulator; community + pro	119	4
terraform-provider-aws	One Go package per service: the IaC population	273	4

Read a high support count as this service is worth emulating to someone, not as our users want this. The live measurement of DevCloud’s own traffic is GET /devcloud/api/unrouted, which accrues behind this page; its ceiling is in coverage.md.

“Unmatched names” is the join diagnostic: a name a source publishes that matches neither the missing set nor a registered service. A large number there would mean name normalisation is dropping matches and the support counts are too low.

Readings

Reading	Value
Upstream model files	431
Registered when sampled	148
R1: missing set `M`	283
R2: `M` with support 3	8
R2: `M` with support 2	49
R2: `M` with support 1	111
R2: `M` with support 0	115
R2: `M` with support ≥ 2	57 (20.1% of `M`)

Full ranking

Ordered by support count, then name: the order the work was done in, so stopping at any point would have stopped on the best surface available.

All 57 services with support ≥ 2 are registered, down to and including workspaces-web; TestDemandSetIsRegistered fails if any of them stops being. All 57 serve at least one operation. Everything below them (support 1 and support 0) is the 226 services that carry no depth commitment. They are registered and engine-served, so a call to one is answered locally rather than billed; what this study declined to promise is that it is answered faithfully. See the two axes.
