ScaleOut In-Memory Database review
A self-hosted Redis-compatible database for distributed applications needing consistency and resilience.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ScaleOut In-Memory Database is an enterprise-oriented, self-hosted in-memory database for organizations running distributed applications on Windows or Linux. It supports Redis data structures, transactions, pub/sub, and the standard Redis client/server protocol, making it a fit for teams that want Redis compatibility while adding automated cluster operations and consistent storage. Supported data models include strings, lists, sets, hashes, sorted sets, streams, hyperloglogs, geospatial data, transactions, and pub/sub.
The published pricing information describes a contact-sales model with licensing on a Server Unit License basis. There is no free plan, while the vendor's downloads page specifies a 30-day trial and the product page advertises a free evaluation. This makes ScaleOut more suitable for organizations evaluating an enterprise deployment than for individual developers seeking a permanently free database. Buyers should expect to discuss requirements and licensing directly with the vendor.
Its main distinction is the combination of Redis compatibility and automated distributed operations. ScaleOut provides automatic cluster management and hashslot distribution, replica placement and rebalancing, failure detection, self-healing, quorum-based fully consistent updates, multithreaded command execution, and parallel backup and restore. These capabilities target teams that want to reduce the operational work of manually managing Redis clusters while maintaining a self-managed deployment model. Choose it when high availability, consistency, and resilience are central requirements; choose another option if you need a free plan, SQL support, or a managed cloud service.
