AVEVA Work Tasks Web Server Farm Connecting to AVEVA Work Tasks Services with AVEVA Work Tasks Databases on a Different Machine

In this scenario, you can maintain a AVEVA Work Tasks Web Server Farm with AVEVA Work Tasks Web Servers and a AVEVA Work Tasks Services cluster on separate machines while the the Databases are installed on a different machine. This deployment provides scalability and high availability of AVEVA Work Tasks Server and AVEVA Work Tasks Web Servers. This is achieved by distributing the load equally among all the machines in the cluster and the AVEVA Work Tasks Web Server Farm.

Multiple servers in the AVEVA Work Tasks Web Server Farm or the cluster run the same AVEVA Work Tasks services. Failure of a server does not impact other servers. You can take the affected server offline while the other servers maintain the service. This type of installation provides Failover. Thus allowing you to easily add or remove machines from the AVEVA Work Tasks Web Server Farm or from the cluster without affecting the execution of workflows.

This is the optimal scenario for heavy load conditions and can be considered if you anticipate heavy load on the Workflow Engine or the AVEVA Work Tasks Web Server.
