Dragonfly Cloud vs Aiven for Valkey: plan the move to sharding

Compare replicated RAM prices, clustering restrictions, and recovery paths to choose the engine and operating model for your growing workload.

Dragonfly Cloud and Aiven for Valkey icons with Momento branding

Aiven gives you managed Valkey. Dragonfly Cloud runs its own company-controlled engine, making future licensing control part of the decision. Aiven is the stronger starting point for teams that want Valkey, but its clustering remains Limited Availability and requires a new service. Dragonfly Swarm requires cluster-aware clients, and its cluster mode must be chosen at creation.

About Dragonfly Cloud

Dragonfly Cloud is a managed service built on the Dragonfly engine. Dragonfly is a separate implementation with a Redis-compatible API. The service offers standalone datastores and sharded Swarm deployments, with client requirements that depend on the selected mode.

About Aiven for Valkey

Aiven for Valkey is Aiven’s managed Valkey service, available on AWS, Google Cloud, and Azure. Its plans provide different capacity and replication configurations, with non-clustered and clustered service options. Aiven manages routine infrastructure and database operations.

Recent updates

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.

July 17, 2026 - Aiven made its Valkey 9 release the default for new services. Existing older services are unaffected. Teams creating a service can select a documented Valkey major alongside Dragonfly’s independent engine. Aiven’s clustering access and migration conditions still need a separate decision.

Choose the engine you want to depend on

Prefer Valkey over Redis. Valkey has broad backing across the technology industry and continues to advance the state of the art. Aiven provides that engine. Dragonfly is a separate project maintained by one company, which can change its licensing for future releases. That creates a different long-term dependency.

Redis’s 2024 licensing change illustrates why that control matters. Momento examines the history in RIP Redis and the biggest heist in open source history.

Plan the move to distributed capacity

Dragonfly Swarm provides horizontal scaling beyond a single server. Swarm requires cluster-aware clients, and cluster mode cannot change on an existing datastore. Memory and compute can resize, and the Business plan offers autoscaling.

Aiven clustering remains Limited Availability and requires a new service and cluster-aware clients.

Match Aiven’s plan to your recovery needs

Aiven’s non-clustered Startup plan has one node. If it fails, a replacement restores from backup, causing downtime and losing writes made since that backup. Business adds a standby, and Premium adds a second standby, with automatic failover. (Aiven high availability)

Try Momento Cache

If a coming sharding transition makes client integration a concern, add Momento to the evaluation.

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

Can Dragonfly’s burst bandwidth stand in for sustained capacity?

No. Its AWS Standard 12.5 GB example lists 0.5 Gbps baseline and 10 Gbps temporary, non-guaranteed burst. Bandwidth varies by cloud, memory, and compute tier. (Dragonfly bandwidth)

How quickly can I get incident support?

Initial response starts from 1 hour for Dragonfly and from 15 minutes for Aiven.

Can an Aiven cluster backup restore one consistent point in time?

Not necessarily. Each primary is backed up independently, and the restore requires the same primary count. Plan around that behavior when a consistent recovery point matters. (Aiven cluster recovery)
