The TVIP-HA architecture requires a cluster of at least two server nodes with specific algorithms capable of detecting a server node’s malfunctioning and duplicate or transfer its services to a functioning node.

TVIP-Heartbeat + TVIP-Monit + LDirector

TVIP-HA employs the Heartbeat and Monit Linux suites to monitor one or more nodes of a TVIP server cluster and establish what policies to implement in case of node malfunctioning. Applications are capable of moving services, for example HTTP servers, from one node to another and of designating the database as master. The TVIP-HA software is installed on every node e and

acts as a cluster watchdog.

The configuration requires a database such as MySQL in a Master-Slave configuration. The nodes refer to a virtual DB address. It is up to the Heartbeat and Monit services.

LDirector allows transforming physical addresses into virtual ones, distributing the load among nodes and diverting it from malfunctioning to functioning nodes.

The configuration is highly scalable and guarantees exceptionally high performances.
