Momento Cache Cluster and Flex enter limited preview

Momento has opened a limited preview of Cluster and Flex configurations for Momento Cache, offering fully managed, single-tenant Valkey capacity for teams needing greater isolation, control, and performance than its Serverless option. Cluster lets users specify instance types, shard counts, replicas, and availability zones, while Flex automatically optimizes resources within user-defined limits; Momento manages provisioning, failover, scaling, upgrades, patches, and topology changes. The service uses a gateway-based architecture that provides a stable RESP endpoint compatible with Redis and Valkey clients while handling traffic challenges such as hot keys, connection storms, TLS, authentication, rate limits, and request coalescing before requests reach Valkey nodes. Pricing is based on deployed capacity without separate request, transfer, or connection charges, with Flex priced per GiB-month and Cluster priced per deployed instance, and the platform supports autoscaling and optional bring-your-own-cloud deployments. Users can request preview access, configure the CLI, create a capacity pool and database, and connect through TLS, while future plans include fine-grained access controls, VPC peering, and S3 integration.
