Dataset releases

Versioned cloud-price, build-versus-buy, and price-history snapshots with reports, source ledgers, full tables, methodology, schemas, and checksums.

Every number highlighted in the ledger points to a dated release. A release is immutable: a correction creates a new version rather than overwriting the old bytes.

Dataset	Coverage	Source window	Status
Cloud build-versus-buy model `build-vs-buy-2026`	Compute, PostgreSQL RDS-like services, object storage, egress, break-even points, and sensitivity.	2026-08-22—2026-08-24	released-snapshot
AWS and Alibaba Cloud pricing model `cloud-pricing-2026`	EC2/ECS, RDS, block storage, object storage, traffic, commitments, and time value.	2026-08-22—2026-08-24	released-snapshot
Cloud price-history model `cloud-price-history-2026`	Long-run compute, storage, and egress price anchors with physical-input and inflation context.	2006—2026; reviewed 2026-08-24	released-snapshot

“Released snapshot” means the files ship with the site together with sources, methodology, schema, and checksums. It is still not a live provider quote.

Release contents

Each version contains:

README.md             scope, dates, units, and reuse warning
release.json          machine-readable version and status
report.md             complete human-readable analysis
methodology.md        comparison and normalization rules
schema.json           table keys and unit conventions
tables/               all CSV and JSON inputs/outputs plus source ledger
charts/               reproducible report charts where available
checksums.txt          SHA-256 for every released file

Three complementary datasets

Cloud pricing · `2026-08-22-v1`

Current-reference AWS and Alibaba Cloud tables for EC2/ECS, EBS/ESSD, S3/OSS, network, PostgreSQL RDS, commitments, and managed-database curves.

Build versus buy · `2026-08-24-v1`

Discrete cost curves, first and durable crossings, and sensitivity tables for compute, PostgreSQL, object storage, and fixed-port egress. Baseline internal labor and migration cost are deliberately excluded.

Price history · `2026-08-24-v1`

Long-run public-price anchors, nominal and real indexes, workload bill baskets, physical-input context, and historical source records from 2006–2026.

Status semantics

released-snapshot means the files ship with the site and pass checksum and headline-value verification. It does not mean the price is current today, that a provider supplied a formal quote, or that two services are fully equivalent. Use the snapshot date and applicability note whenever quoting a value.
