Kiuru MSSP supports the clustering of servers for higher performance and availability. Servers in a clustered system use the same database, and traffic is divided between them by a load balancer. The load balancer also detects MSSP failures and redirects traffic accordingly. In a clustered setup, HomeMSSPs are in one cluster and AE MSSPs are in another.
Kiuru MSSP supports e.g. F5 BIGIP/Radware Alteon load balancers or Apache proxy for mutual TLS authentication, which is a mandatory requirement in the ETSI TS 102 204 standard. Complete system high-availability also requires redundant databases and load balancers.
