Memorystore for Valkey vs Percona for Valkey: managed capacity or a platform you own

Choose Memorystore for Valkey when you want Google Cloud to operate the service while your team controls capacity. Choose Percona for Valkey when you want validated software and database expertise on infrastructure you select. Percona’s advisory support and hands-on operations are separate offerings, so the choice also determines which work stays with your team.

Recent updates

September 24, 2026 - Memorystore’s current Valkey 9 release became generally available. Teams evaluating Valkey 9 can now select that release. The current version table lists that release as the default. Upgrades cannot be downgraded.

September 2, 2026 - Momento introduced Cluster and Flex capacity for Momento Cache. Both provide dedicated, managed Valkey resources. Cluster exposes topology choices, while Flex selects topology within capacity bounds, giving teams a choice in how they configure capacity while Momento operates the cluster.

Choose a managed service or your own platform

Memorystore narrows capacity planning to a managed service’s predefined choices. Its six regular clustered node types pair CPU and memory, with shards and replicas adding configurations. You can deploy the Memorystore Cluster Autoscaler to adjust shard counts from CPU and memory demand. Your team configures and operates that automation.

Percona fits teams that want to retain infrastructure choices. Its validated Valkey Linux packages and expertise support cloud, on-premises, and hybrid deployments.

Memorystore’s starting price is from $32.40/GB-month. Request a Percona quote for the services you want around your chosen infrastructure.

Assign execution before purchasing support

With Percona Expert Support, you get advice and your team performs the work. ExpertOps separately handles agreed database operations, including maintenance and approved changes. That can take database work off your team’s plate while you retain architecture and change decisions.

For a routine database patch, decide whether your engineers will execute Percona’s advice or ExpertOps will perform the agreed change. The underlying platform still needs an owner. Percona’s Managed Services policy leaves operating-system, Kubernetes, and application support with the customer. Memorystore puts service operations with Google, leaving your team to choose capacity and configure scaling automation.

Try Momento Cache

If you want to hand off routine patching and failed-node operations, Momento Cache provides managed cluster health, failover, updates, and security patches.

Momento Cache puts dedicated, high-performance Valkey behind a managed gateway that keeps client integration stable as your application grows. Choose Cluster for direct control over instance types, shards, and replicas, or Flex to set capacity and replication bounds while Momento selects the topology. Both include built-in autoscaling and fully managed cluster operations.

Talk to a Momento solution engineer to evaluate the capacity model and configuration that fit your workload.

Frequently asked questions

How do the uptime commitments compare?

Memorystore offers 99.99% uptime. Percona’s hosted Valkey uptime percentage is unknown from its public service policies.

Can I change Memorystore cluster mode later?

Cluster mode cannot change in place. Enabled mode supports sharding and cluster-aware clients. Disabled mode uses one shard and ordinary clients. Choose the mode for your application up front, then resize capacity within it as needed.

Can applications outside Google Cloud use Memorystore?

Yes, through supported networking. Memorystore uses private endpoints through Private Service Connect, so outside-cloud applications need an appropriate network path.

How quickly can support respond?

Google Cloud support offers response from 5 minutes. Percona support offers response from 15 minutes.
