The framework is fully-scalable as well. You can add extra database servers if needed to relieve high loads on the data end. The CeleriQ.NET engine rides on top of SQL Server and allows you to spread the index across multiple database servers. In addition, a web farm may be used for high use websites and hit one or more database servers on the back-end. There is no session state or other identifying information about requests that are the root of common problems. All hits to the CeleriQ engine are atomic. There is never a request that requires some later, dependent request. The engine is multi-threaded to handle an arbitrary number of tasks. This ensures that your database server farm configuration or web server farm configuration is not impacted by CeleriQ.
Hardware
Since the CeleriQ index is read-only, scalability is really just a matter of having a RAID configuration and adding more drives. On all but the highest volume websites, a single database server configured with a RAID is all that is needed for fast throughput.
