Google Cloud Memorystore
What Google Cloud Memorystore is
Google Cloud Memorystore is a fully managed in-memory service for Valkey, Redis, Redis Cluster and Memcached, with sub-millisecond data access, scalability and high availability. It automates provisioning, replication, failover and patching. Valkey and Redis Cluster support zero-downtime scaling up to 250 nodes and terabytes of keyspace; their listed availability SLA is 99.99%, while Standard Tier Redis has a 99.9% SLA. Memorystore for Valkey offers approximate and exact nearest-neighbor vector search for generative AI applications. Connectivity options depend on engine: Valkey and Redis Cluster support Private Service Connect, while Redis and Memcached support Private Service Access and Direct Peering using private IP. Security features include network isolation, IAM integration and encryption in transit. Monitoring and custom alerts are available through Cloud Monitoring. Pricing depends on engine, region and configuration: listed examples are $0.05 a month for Redis and $0.19 a month for Valkey and Redis Cluster. These are example rates, not a single price for every setup.

Plans
| Plan | Billed and limits | Price |
|---|---|---|
| Memorystore for Redis | Based on provisioned capacity, service tier, and region; read replicas are billed by capacity and node count. · The displayed rate is from an Iowa Standard Tier M3 pricing example; capacity tiers have different rates | $0.05 a month |
| Memorystore for Valkey | Per second based on provisioned capacity; price varies by region and node type. · Price shown is for a highmem-medium node in Iowa; backups and AOF persistence can incur additional charges | $0.19 a month |
| Memorystore for Redis Cluster | Hourly cost depends on shard and replica count, node type, and region. · Example uses 5 shards and 5 replica nodes in Iowa; AOF persistence and backups can incur additional charges | $0.19 a month |
| Memorystore for Memcached | Based on total vCPUs and memory provisioned across nodes, with rates depending on region and memory per node. · Iowa example rates shown for vCPU and a node with up to 4 GiB; larger nodes use a different memory rate | On request |
