Google Memorystore Redis allocated cache capacity · Redis key reads per second

Feature: Google Memorystore Redis allocated cache capacity. Estimated monthly service charges by Redis key reads per second. Adapter hosting and Tensor9 fees are excluded. Source: us-central1; target: eastus; currency: USD. 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 4 vCPU, 9.75 GiB memory and 0 GiB SSD at 0 operations/s to 16 vCPU, 48.75 GiB memory and 0 GiB SSD at 100,000 operations/s. From 1,000,000 operations/s the workload exceeds the planning range and the target is unpriced. Curve assumptions

• Only the selected native meter varies; other usage quantities and assumptions retain their displayed 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; capacity coefficients are editable authored planning guesses, not measured capacity.
• The origin is the exact registered google::1.0.0::memorystore::redis identity. Renamed products and future aliases require explicit mapping updates.
• Source allocated CPU-hours and memory-hours establish independent minimum target allocation. Neither management API requests nor a key-operation count is an instance count.
• Peak weighted key-operation work and resident data can promote the allocation above those minima. CPU rounds to whole cores and RAM to quarter GiB.
• CPU and RAM are aggregate resources over 730 hours. Selected backend prices own replica count, availability configuration and actual instance shapes.
• A multi-core estimate assumes the workload can be partitioned. Redis command execution, hot keys, cross-key transactions and clustering can prevent linear scale.
• Zero allocated resources and zero workload do not prove target scale-to-zero; the selected backend may retain a provisioned minimum.
• Memorystore bills provisioned GiB-hours by capacity tier; the CPU meter is free but still sets the target CPU minimum.
• The Azure profile lowers ElastiCache node types to Azure Cache for Redis Enterprise sku_name values (cache.t3.medium becomes Enterprise_E10-2). Azure lists each Enterprise cache with its two data nodes and has no single-node tier, so one- and two-copy estimates both bill two copies; the model bills the selected RAM without rounding to an E size. Azure retires Azure Cache for Redis Enterprise on 2027-03-30 (https://azure.microsoft.com/en-us/pricing/details/cache/). Azure Managed Redis Memory Optimized M10 (12 GB) lists USD 0.216 per hour (meterId 40cb6a35-94af-5d34-8312-da0bc5a67894), 0.432 with high availability; the profile does not select it. The CPU rate is zero because capacity GiB is the billed quantity, and the billed capacity is the cache family’s selected RAM rather than the generic planning CPU tier’s RAM; key-operation CPU demand raises cost only through the family’s RAM-per-CPU shape, which approximates managed throughput growing with capacity and is not a measured fit. The capacity charge and the minimum compare using their maximum, not their sum.
• Cache storedGiB represents resident RAM footprint, not billable SSD. Persistence, snapshots and backup disks require a separate explicit allocation.
• 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 workload family already selected resource-hours; the throughput coefficient is not applied again.
• Copies and allocation fractions change cost only; they do not increase modeled primary capacity.
• Cache resident GiB is RAM provenance. Family-selected RAM-hours cover the working set;
• no SSD allocation is modeled. Persistence, snapshots and backup disks remain excluded.

Google Memorystore Redis allocated cache capacity · Redis key reads per second

Feature: Google Memorystore Redis allocated cache capacity. Estimated monthly service charges by Redis key reads per second. Adapter hosting and Tensor9 fees are excluded. Source: us-central1; target: us-east-1; currency: USD. 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 4 vCPU, 9.75 GiB memory and 0 GiB SSD at 0 operations/s to 3 nodes of 64 vCPU, 155 GiB memory and 0 GiB SSD each at 1,000,000 operations/s. Curve assumptions

• Only the selected native meter varies; other usage quantities and assumptions retain their displayed 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 → us-east-1, 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; capacity coefficients are editable authored planning guesses, not measured capacity.
• The origin is the exact registered google::1.0.0::memorystore::redis identity. Renamed products and future aliases require explicit mapping updates.
• Source allocated CPU-hours and memory-hours establish independent minimum target allocation. Neither management API requests nor a key-operation count is an instance count.
• Peak weighted key-operation work and resident data can promote the allocation above those minima. CPU rounds to whole cores and RAM to quarter GiB.
• CPU and RAM are aggregate resources over 730 hours. Selected backend prices own replica count, availability configuration and actual instance shapes.
• A multi-core estimate assumes the workload can be partitioned. Redis command execution, hot keys, cross-key transactions and clustering can prevent linear scale.
• Zero allocated resources and zero workload do not prove target scale-to-zero; the selected backend may retain a provisioned minimum.
• Memorystore bills provisioned GiB-hours by capacity tier; the CPU meter is free but still sets the target CPU minimum.
• ElastiCache for Redis OSS node-based clusters bill whole nodes per hour; the capacity rate is cache.r7g.large’s price per GiB, and each replica is another full-price node. Valkey nodes list 20% lower (cache.r7g.large 0.1752 per hour, 0.0134047 per GiB-hour); ElastiCache Serverless is not selected. The CPU rate is zero because capacity GiB is the billed quantity, and the billed capacity is the cache family’s selected RAM rather than the generic planning CPU tier’s RAM; key-operation CPU demand raises cost only through the family’s RAM-per-CPU shape, which approximates managed throughput growing with capacity and is not a measured fit. The capacity charge and the minimum compare using their maximum, not their sum.

• 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; capacity coefficients are editable authored planning guesses, not measured capacity.
• The origin is the exact registered google::1.0.0::memorystore::redis identity. Renamed products and future aliases require explicit mapping updates.
• Source allocated CPU-hours and memory-hours establish independent minimum target allocation. Neither management API requests nor a key-operation count is an instance count.
• Peak weighted key-operation work and resident data can promote the allocation above those minima. CPU rounds to whole cores and RAM to quarter GiB.
• CPU and RAM are aggregate resources over 730 hours. Selected backend prices own replica count, availability configuration and actual instance shapes.
• A multi-core estimate assumes the workload can be partitioned. Redis command execution, hot keys, cross-key transactions and clustering can prevent linear scale.
• Zero allocated resources and zero workload do not prove target scale-to-zero; the selected backend may retain a provisioned minimum.
• Memorystore bills provisioned GiB-hours by capacity tier; the CPU meter is free but still sets the target CPU minimum.
• ElastiCache for Redis OSS node-based clusters bill whole nodes per hour; the capacity rate is cache.r7g.large’s price per GiB, and each replica is another full-price node. Valkey nodes list 20% lower (cache.r7g.large 0.1752 per hour, 0.0134047 per GiB-hour); ElastiCache Serverless is not selected. The CPU rate is zero because capacity GiB is the billed quantity, and the billed capacity is the cache family’s selected RAM rather than the generic planning CPU tier’s RAM; key-operation CPU demand raises cost only through the family’s RAM-per-CPU shape, which approximates managed throughput growing with capacity and is not a measured fit. The capacity charge and the minimum compare using their maximum, not their sum.
• Cache storedGiB represents resident RAM footprint, not billable SSD. Persistence, snapshots and backup disks require a separate explicit allocation.
• 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: cache.r7g.16xlarge has 64 vCPUs and 419.09 GiB (https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/CacheNodes.SupportedTypes.html); cluster mode shards up to 500 nodes (https://docs.aws.amazon.com/AmazonElastiCache/latest/dg/Shards.html).
• Stored GiB already includes the origin family’s physical footprint assumptions; no second storage amplification is applied.
• The workload family already selected resource-hours; the throughput coefficient is not applied again.
• Copies and allocation fractions change cost only; they do not increase modeled primary capacity.
• Cache resident GiB is RAM provenance. Family-selected RAM-hours cover the working set;
• no SSD allocation is modeled. Persistence, snapshots and backup disks remain excluded.
