High availability overview

PEM Partner Repository or PEM Partner Provisioner can be deployed in an integrated network of external systems and trading partners to form a cohesive business ecosystem.

Prolonged application or system outages can have significant business consequences. A high availability configuration reduces or eliminates system downtime during operations or planned and unplanned outages. Follow best practices to assure high availability of all components. High availability helps you avoid or minimize downtime when a part of your system stops running by shifting work to another part of the system. In this scenario, the rest of your system can continue processing while the failed component recovers.

Approaches can be taken to increase the resiliency of PEM Partner Repository or PEM Partner Provisioner to environmental, hardware, or software faults or failure. Techniques and architectural patterns can minimize the impact on the overall ecosystem during planned or unplanned system outage. At the same time, a pragmatic approach to availability recognizes that one cannot implement high availability techniques at the detriment of other architectural considerations such as capital cost, ongoing total cost of ownership, or manageability.
