Google Secret Manager · Secret-version accesses

Google Secret Manager · Secret-version accesses: monthly service charges by Secret-version accesses. Exact values are in the following table.Google Secret Manager · Secret-version accesses: monthly service charges by Secret-version accesses. Exact values are in the following table.
Comparison pills describe all sampled scale points; amounts beside each service are for the named workload. Costs The Same means within 20% at every point. Costs Depend includes mixed results and unpriced samples. Sampled monthly charges in USD, rounded to cents. Difference means target minus origin; a positive difference means the target costs more. Estimated allocation, not benchmark calibrated: sized from 2 vCPU, 8 GiB memory and 100 GiB SSD at 0 operations/s to 32 vCPU, 128 GiB memory and 100 GiB SSD at 10,000 operations/s. Curve assumptions
  • Monthly operation quantity varies with this steady average rate; stored inventory and other meters retain their defaults. Other native meters and workload assumptions retain their explicitly displayed default quantities. Workload translation and capacity assumptions are not benchmark measurements.
  • Native monthly usage priced at the cited provider list prices; listed target allowances apply where present, excluding invoice credits, taxes and negotiated discounts. Rates as of 2026-10-22: us-central1 → eastus, USD/month.
  • Source prices are reference charges, not an invoice. Target lines cover selected service usage/configuration only; adapter hosting and Tensor9 fees are excluded.
  • Samples of explicit prices are not performance measurements or capacity qualification. No interpolation or break-even guarantee is implied.
  • Variant assumptions show the first axis sample; any axis-dependent configuration is described by this curve’s workload note.
  • Rates are cited provider list prices, editable for discounts, commitments or another region. Workload translation and capacity coefficients remain editable planning assumptions, not benchmark measurements or a commercial quote.
  • Default-zero rates are explicit assumptions, not evidence that the deployed service or resource is free.
  • Provisioned-unit minimums use an editable approximate allocation floor. Modeled target service cost is max(usage/allocation, minimum), with billable network, durable staging and dependent sinks added separately; actual RU/TU sizing, scaling increments and throughput remain unqualified.
  • Durable staging is priced once: provisioned targets include adapter state in their selected allocation; native targets add a separate staging allocation when required. Adapter hosting is a separate allocation and must exclude resources already priced as staging, workers or target capacity.
  • A declared adapter mapping and cost model do not establish implementation availability or service equivalence.
  • This exact directed mapping has a design profile. Cost modeling does not establish an implemented or deployable adapter.
  • Origin unit prices are cited provider list prices. Retention, amplification, and capacity coefficients are authored planning guesses; they are editable, not measured capacity.
  • Reverse-cloud Secret Manager adapters are declared designs. This planning scenario assumes a durable record plus reconciled provider copy; it does not certify a delivered implementation or promote availability.
  • Application reads use durable adapter records. Managed operations estimate independent backend reconciliation, not a provider secret-access charge on every application read.
  • Provider reconciliation operations use the vault-operation rate; Standard secrets have no storage meter.
  • Row-store throughput (capacityOpsPerVcpuSecond, default 1500) is measured-by-tensor9 as a lower bound: the DynamoDB adapter on Cloud SQL db-custom-2-7680 (2 vCPU, PostgreSQL 16, us-west1) served 2,974 ops/s of YCSB-A at 16 threads without recorded saturation (src/main/kotlin/t9/prime/equiv/generated/eval/CloudsqlPostgresqlYcsbAT16GoYcsbV1_0_0.kt). Published CPU-bound pgbench reaches 3,101 read-write transactions and 20,289 point reads per vCPU-second (AWS z1d.2xlarge, PostgreSQL 14.5), so actual capacity is likely higher. Reads and writes share one coefficient: at the same adapter version, read-only YCSB-C was not faster than 50%-update YCSB-A.
  • Log-broker throughput (capacityStreamMiBPerVcpuSecond 20 at 0.5 utilization, 4 GiB RAM per vCPU) is provider-documented by Google Managed Service for Apache Kafka sizing (https://docs.cloud.google.com/managed-service-for-apache-kafka/docs/plan-cluster-size): write-equivalent bytes are replicated writes plus a quarter of reads. Producer batches below 10 KB lower per-CPU throughput; that penalty is not modeled.
  • Disk utilization 0.8 is provider-documented headroom below Cloud SQL automatic storage increase, which triggers near 91-95% full (https://docs.cloud.google.com/sql/docs/postgres/instance-settings). The 20 GiB reserve exceeds PostgreSQL’s 1 GB default max_wal_size; the remainder of that reserve is unmeasured.
  • CPU tiers double from 2 vCPUs to the target’s largest node at 4 GiB per vCPU; each target’s documented largest node bounds CPU, RAM, RAM per vCPU and disk, and the durable staging database uses Cloud SQL Enterprise (96 vCPU, 6.5 GiB per vCPU, 624 GiB, 64 TiB). Targets billed per capacity unit or throughput unit are sized by their backend instead.
  • No public evidence: peak/mean work (2) and the RAM working-set fraction (0.1). Proposed measurements: the p99 one-minute rate over the monthly mean from customer CloudWatch metrics; the buffer hit ratio while stepping RAM under a fixed YCSB-B load.
  • Node bounds: Cloud SQL Enterprise allows 1-96 vCPUs at 0.9-6.5 GB per vCPU and up to 64 TB with a dedicated vCPU (https://docs.cloud.google.com/sql/docs/postgres/instance-settings).
  • Stored GiB already includes the origin family’s physical footprint assumptions; no second storage amplification is applied.
  • The operations/vCPU coefficient supplies the compute requirement alongside explicit resource-hour minima.
  • Copies and allocation fractions change cost only; they do not increase modeled primary capacity.
  • Secret Manager pricing: https://cloud.google.com/secret-manager/pricing
  • Azure Retail Prices API: https://prices.azure.com/api/retail/prices
Cost scope: Modeled target native service and explicitly modeled state allocation; hosting and Tensor9 fees only when supplied. Excluded costs and workload features:
  • Free allowances, committed discounts, credits, taxes and negotiated rates.
  • Commercial Tensor9 fees and operations labor unless entered separately.
  • Regional replication, customer-managed KMS, source free allowances and rotation functions.
  • Taxes, discounts, credits and free-tier allowances not explicitly listed by this model.
  • Unmodeled dependent services, task execution and operations outside the selected workload family.
