High-Availability Network Architecture and Testing
 
Deployment Configuration: Simple
Deployment Configuration: Fully Redundant
To take advantage of the Terracotta active-mirror server configuration, certain network configurations are necessary to prevent split-brain scenarios and ensure that Terracotta clients (L1s) and server instances (L2s) behave in a deterministic manner after a failure occurs. This is regardless of the nature of the failure, whether network, machine, or other type.
This section outlines two possible network configurations that are known to work with Terracotta failover. While it is possible for other network configurations to work reliably, the configurations listed in this document have been well tested and are fully supported.
