Aiven for Valkey is a managed in-memory key/value datastore for real-time workloads, including caching, message queuing, session storage, retrieval-augmented generation, and real-time analytics. The product page identifies Valkey 9.1 as its current version. Valkey 9 and later services include Bloom and Search modules by default; Search handles vector, full-text, numeric, and tag queries. Aiven documents compatibility with Redis OSS 7.2.4 and migration support from Redis implementations and Valkey databases. Customers can manage the service through Aiven Console, CLI, API, or Terraform. Aiven advertises a 99.99% uptime SLA, automatic failover, and backups every 12 hours on applicable plans. Security options include encryption in transit and at rest, SSO/SAML, and VPC peering. The free plan has one node, 1 CPU, and 1 GB RAM, but excludes integrations, support services, VPCs, static IPs, and the 99.99% SLA. Pricing includes a free plan, paid plans from $15/mo, and a 30-day trial.

Hazelcast Platform brings a distributed compute engine and an in-memory data store together for real-time and AI-driven applications. It can process streaming data before storage, supporting action on data in motion, and provides fast reads and writes for interactive request/response workloads. SQL processing, stateful processing, event-time windows, and Java and SQL are listed capabilities. WAN Replication synchronizes clusters and supports automatic failover to a secondary cluster for disaster recovery. Security features include JAAS role-based access controls and TLS encryption for data moving between nodes and applications. The platform runs on public and private clouds, is available through AWS, Google Cloud, and Azure marketplaces, and supports hybrid deployment. Its Kafka Connector processes Apache Kafka topic streams and sends processed data back to Kafka. Hazelcast identifies mission-critical, data-intensive AI workloads as a focus, including use in financial services, retail, supply chain, and healthcare. The platform is available for Linux, macOS, and Windows, as well as through an API and self-hosted deployment. A free plan and free 30-day Enterprise trial are listed; the trial requires a requested license key. The annual self-managed subscription includes professional support, with pricing available by request.
