The Payment Hub should provide adequately high availability at the DFSP. This depends on environment, availability of the overall environment (dual data centers, network redundancy), customer expectations and regulatory requirements.
The Payment Hub should be able to receive transactions, even in the case the Account Management System (AMS) is not available on behalf of the DFSP.
To fulfill these requirements and reduce overall cost, in a modern architecture, software based replication, clustering, coordination services can be utilized, although easy installation and operation should not be compromised. This will require the necessary enhancements in the Payment Hub.
