WEB ACT application Server architecture

WEB ACT application Server architecture provides:

Smaller table size - thus faster query processing.
Variable application structure for individual customers - database driven menu structure within individual databases allows bespoke additional modules or software customisation for local requirements.
Graceful system growth to cope with increased customer demands.
Single point monitoring of access records and system security.
Centralised recording of application workflows.
Individual servers use hardened Linux to provide high security.
Servers use raid technology to provide data security and fault tolerance.
Single code base provides maximum code acceleration through code caching techniques.

WEB ACT Server Cluster Architecture

WEB ACT Server Cluster Architecture:

Code base switching if server failure occurs.
Automatic database replication between pairs of servers providing server switching in case of server failure.
Cross server rolling backups, automated on live databases.
No requirement for users to log off during backup.
Backup processes lock database tables to allow seamless backup.
Small database sizes allow fast rolling backups. Rolling backups stored on paired server.
Overnight backup to a separate ftp server on site.
Overnight backup to an offsite server.
On demand download of full database data available at all times to customers. Dynamically updated on demand.

WEB ACT Server Cluster Expansion provides:

Addition of paired replicated database server engines to handle high application processing demands.
Database query processing handled by extension database servers.
Application code directly supports multiple database engines without processing overhead.
Database servers can be separated from the code servers to further increase processing capability.
