Redis Cloud vs Momento: connection growth and scaling decisions

When your application fleet grows faster than its dataset, connection capacity can drive the cache decision. Redis Cloud offers managed Redis with plan-specific limits and customer-initiated scaling. Momento Cache offers dedicated, high-performance Valkey behind a gateway designed for millions of clients.

For a growing application, prefer Valkey over Redis. Valkey is widely backed across the tech industry and continues to advance the state of the art. Momento brings that foundation to your team through Cluster and Flex, both with built-in autoscaling and different ways to select capacity.

About Redis Cloud

Redis Cloud is Redis’s managed database service, offered through Essentials and Pro plans. It runs the Redis engine and provides hosted databases with managed client routing. Cloud availability, capacity, and connectivity options depend on the plan.

Recent updates

September 22, 2026 - Redis announced Smooth Scaling for Cloud Pro. It improves the resizing process, while your team still initiates capacity changes. If recurring resize decisions are the work you want to hand off, compare that operating model with the built-in autoscaling in both Momento Cluster and Flex.

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.

Plan for the fleet connecting to the cache

Redis Cloud Essentials RAM plans allow 256–10,000 concurrent connections. A small dataset can still need a larger plan to accommodate the applications connecting to it.

Pro has no fixed database-level connection limit. Its practical capacity depends on your infrastructure and workload.

Momento Cache puts dedicated Valkey behind infrastructure built for millions of clients. Its gateway handles connections, TLS, and authentication, leaving the Valkey cluster to serve the workload. Familiar clients connect in standalone mode without managing node discovery or topology changes.

Hand off topology changes without giving up capacity control

A growing fleet can make capacity reviews recurring work. With Redis Cloud Pro, your team decides when and how much to resize.

With Momento Flex, you set capacity and replication bounds, and Momento selects and adjusts the topology. Cluster gives you precise control over instances, shards, replicas, and zones. Both include the same built-in autoscaling. Momento also manages cluster health, failover, rolling updates, and security patches, so your team can focus on the application.

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

How do clients connect?

Redis Cloud’s proxy endpoint simplifies client-side shard routing. Both Essentials and Pro offer public endpoints, but private connectivity requires Pro. Momento’s managed gateway presents standalone-mode access.

Which uptime SLA applies?

The Redis Cloud SLA offers 99.999% for Active-Active. Active-Active counts downtime only when all databases in the deployment fail.

Momento offers a 99.99% uptime SLA.

Does Active-Active remove application failover work?

No. Your application handles inter-region client failover and failback with Redis Cloud Active-Active.
