ScaleArc

The core of ScaleArc's business is its software that inserts transparently between applications and databases, creating an agile data tier without requiring any code changes to the application or database. This allows the software to manage database traffic, providing features like automatic failover, read/write splitting, query caching, and real-time analytics. The business model is centered on selling this software to enterprises that require high-availability and high-performance database operations, serving system and SQL administrators in both on-premise and cloud environments. Its client base includes large-scale, transaction-based systems for companies like Dell, NASDAQ, and Microsoft.

ScaleArc's product functions as a database-aware proxy that abstracts the application from the database, which enables zero downtime for applications. Key features include automatic failover, which shields applications from database downtime by instantly rerouting traffic away from unavailable servers. The software improves performance through intelligent load balancing, distributing read queries across multiple replica servers while directing write traffic to the primary server. It also offers a query caching mechanism that can deliver content significantly faster by storing and reusing responses to frequent queries. This functionality supports a range of SQL databases, including Microsoft SQL Server, MySQL, and more recently, PostgreSQL. The platform provides deep visibility into the data tier, offering analytics and a centralized logging system to help administrators troubleshoot and optimize performance. This allows companies to scale their database infrastructure, migrate to the cloud with minimal disruption, and ensure continuous operation.
