OCI Cache vs Momento: size for traffic as well as memory

Choose OCI Cache for managed Valkey alongside an OCI application, sizing for bandwidth and connections as well as memory. For a workload on a supported cloud, consider Momento when client growth is becoming a capacity constraint. Its gateway scales to millions of clients, with built-in autoscaling in both Cluster and Flex.

About OCI Cache

OCI Cache is Oracle’s managed caching service in Oracle Cloud Infrastructure. It supports Valkey and Redis, with sharded and non-sharded deployments. Customers configure memory, nodes, and sharding, and applications connect through private endpoints using supported network routing.

Recent updates

September 9, 2026 - Oracle added cross-region replication. OCI now offers a regional recovery option for non-sharded clusters in selected region pairs. It is active-passive, with customer promotion and application rerouting, so regional recovery remains a separate design choice from the local capacity needed to serve clients.

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.

Unit costs matter at scale

At 1 TB, or 1,000 GB, the starting rates above imply $30,780 per month for OCI Cache and $20,700 per month for Momento Cache Cluster. That is $10,080 per month, or about 33%, less for the selected capacity with Momento Cluster. As the dataset grows, the difference in unit price becomes a larger monthly capacity expense.

Choose resources that fit your workload

With OCI Cache, a small dataset can still call for a larger memory allocation if the application needs more bandwidth. Oracle allocates bandwidth with provisioned memory, so throughput belongs in the sizing decision. Your team chooses memory, node count, and sharding as requirements change.

Momento gives you the control to shape dedicated capacity around your application. With Momento Cache Cluster, you choose instances, shards, replicas, and zones. Flex adjusts topology within your capacity and replication bounds. Both include the same built-in autoscaling. Momento manages cluster health, failover, updates, and security patches in both, keeping the operating work off your team.

Be aware of hard service constraints

OCI Cache supports up to 40,000 connections per node. As an application fleet grows, connection distribution and pooling become part of its capacity plan. Private endpoints require suitable network routing, including for clients outside OCI.

Momento lets you connect a much larger audience through familiar standalone-mode clients. Its gateway scales to millions of clients, handling connections, TLS, authentication, and routing ahead of dedicated Valkey. Applications keep a stable connection interface as Momento manages the cluster underneath. Hot-key handling and request coalescing help the gateway serve demanding traffic, too.

Try Momento Cache

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.

Frequently asked questions

Does OCI Cache support cross-region recovery?

Yes. OCI cross-region replication is asynchronous and active-passive, available for non-sharded clusters in selected region pairs with at least 8 GB per node. Your team promotes the secondary and redirects applications during recovery. Participating clusters do not support backups, and recent unreplicated writes may be lost.

Are OCI backups automatically scheduled?

OCI supports managed snapshots. Scheduled backups require an external scheduler calling the API, so your team owns that automation.

What service and support commitments are available?

OCI offers a 99.95% uptime SLA and support response from 15 minutes.

Momento offers a 99.99% uptime SLA and support response from 15 minutes. One Momento support plan covers all products and accounts in your organization.
