High availability deployment

In the Highly Available (HA) deployment pattern, duplicates of all Blue Prism components can be installed to provide redundancy. All components are in active-active patterns, and load balancers are frequently required for network connections to resolve across multiple instances of the same component (see High availability deployment network architecture for the positioning of these).

It is not possible for SS&C Blue Prism to test and validate every deployment variation for every scale. The deployment patterns used as an example in this guide illustrate how the products are designed to work together to support customer architects and deployment engineers in making informed decisions. It should not be assumed that they can be followed exactly, nor that they will be appropriate for every real-world use case. It is expected that organizations will apply appropriate expertise to adapt and vary these designs to fit their own needs.

High availability

All components are in active-active patterns, and load balancers are frequently required for network connections to resolve across multiple instances of the same component, see High-density deployment for the positioning of these components.

It is also possible to deploy one or more additional environments in an active-passive mode for disaster recovery, including by distributing them across different regions. In such a pattern it is only the SQL Always On Availability Group which is shared between the environments, every other component is simply replicated in the passive environment.

Balance of resiliency and cost

Deploying multiple copies of any component is optional. A highly available architecture may not include multiple copies of some components, where there is no business requirement for resiliency of that component.

It is also still possible to co-locate components on the same hardware in the same way as for the standard and high density patterns, and it is assumed that in reality highly available deployments will do so in some cases in order to find an appropriate balance of resiliency and cost.
