ScaleArc is a database load balancing software that provides continuous availability at high performance levels.

ScaleArc is a database load balancing software that inserts transparently between your apps and your databases to keep applications working seamlessly despite interruptions and switchovers. Thanks to deep integration with Microsoft SQL Server™ AlwaysOn technology and MySQL™ automatic failover, it maintains continuous availability for applications despite database failover and delivers high performance.

Learn how ScaleArc works ― in 90 seconds

Use ScaleArc to deliver uptime, performance, and scale for your critical apps in a database environment.


Ensure zero downtime

Ensure zero downtime during database maintenance, and reduce risk of unplanned outages by automating failover processes and intelligently redirecting traffic to database replicas.

Automated database failover

ScaleArc monitors your servers automatically migrating client connections from a failed database node to a healthy node in the cluster. This architecture dramatically reduces app errors and prevents apps from hanging.

Surge Queuing

ScaleArc reduces application errors by throttling and queuing load in case of increasing replication lag during crashes or failover, preventing service outages. ScaleArc's surge queue effectively limits the load with no change in query order.

Read Write Split

ScaleArc's read/write functionality boosts performance for read-heavy applications. Without any application modification, ScaleArc immediately recognizes which queries are reads and which are writes and transparently directs reads to the secondary and writes to the primary.

Improve application performance

Dramatically improve application performance with Scalearc’s connection pooling, query caching and intelligent routing for faster database queries

Connection pooling and multiplexing

ScaleArc saves time with its connection pooling and multiplexing. Instead of connections sitting idle, ScaleArc delivers only those connections that are necessary for active concurrent queries and multiplexes the rest to make database access faster.

Transparent in memory query caching

ScaleArc delivers user content 6x to 60x faster by caching responses for simple and frequently-called queries as well as for more complex queries with its memory cache. Additionally, it helps you identify queries for caching.

Query routing

ScaleArc seamlessly handles SQL traffic routing in case of failure. ScaleArc can reduce application errors that result from failovers by routing read only sessions to new servers.

Get real time visibility

ScaleArc real time analytics enable you to rapidly identify problem queries, such as slow, frequent queries. You can also take rapid action on these insights, adding queries to cache or blocking them.

Realtime analytics

ScaleArc's comprehensive, real-time analytics easily identify problematic queries or frequent queries for caching, performance troubleshooting, and to assess the impact of sql queries with SQL analytics. Features include break down of query traffic, bucketing and analyzing queries and searching logs.

With ScaleArc, you increase operational efficiencies and speed up troubleshooting, using an aggregate, centralized view of your ScaleArc traffic running across multiple database servers in near real-time. ScaleArc eliminates the need to connect logs for each database, application, and server.

ScaleArc provides the ability to quickly go back in time, retrieve historical data, and get the insight you need for faster problem identification and resolution like a flight recorder or "black box”.
