Continuent Unicluster abstracts multiple database servers as a single, virtual large database so that continuous access to the data is provided without sacrificing processing power, reliability or data integrity.

Continuent is a fully transparent solution that can be added to any application environment. It is designed to support all major open source and commercial databases, either in a homogeneous or heterogeneous configuration. The heterogeneous database support can help your migrate from one database to another or migrate to a new major release, or service a multi-vendor database environment, if it is part of the existing application.

1. Fully transparent failover for all transactions. Even transactions that were in-flight during a failure event. This is automatic continuity at the transaction level. No lost transactions and users left looking at error messages or needing to restart their transactions. This helps you avoid lost business due to database outages, which translates to business continuity. Your application no longer has to contain special error processing for this condition. All data will be left in a correct and consistent state. Continuent provides a true-self healing capability from the applications’ view of the database tier.
2. Instantaneous failover. All database servers are fully up to date and all have the correct data, all the time. No more long failover times and or inconsistent data. If a database server fails, it is automatically removed from the grid, all users will be reconnected to another database server, and any in-flight transactions are automatically restated. Continuent accomplishes this real-time and without manual intervention.
3. Full scale-out capabilities. Scale your database vertically by adding low cost commodity hardware, scale horizontally by data partitioning. In this way, scalability is provided both for queries that are reading the data and queries that create or update data. Flexible load balancing capabilities insure the effective use of your hardware investment.
4. Heterogeneous database support. Some applications may involve more than one brand of database, involve a migration from one database brand to another, or simply involve upgrading to a new release of the same database. Continuent supports it all - transparently and seamlessly.
5. Low TCO, high ROI. Installing Continuent regardless of your application server or database brand is easy, fast and cost effective.
