OIPA REST Services

Multiple load tests were conducted for REST services with a 4-JVM cluster. The objective of the test was to determine the maximum sustainable throughput while keeping database server health within acceptable limits. The cluster topology consisted of 2 JVMs deployed across two virtual machines, which were load balanced using a virtual load balancer. The test was executed with 250 concurrent users. The total test duration was 70 minutes, consisting of a 10-minute ramp-up period followed by a 60-minute steady-state execution window used for performance measurements.

The following REST JSON services were included in the test:

• exposedComputation_Rest_Json

• policyValuation_Rest_Json

• clientInsert_Rest_Json

• policyInsert_Rest_Json

• ActivityInsert_Rest_Json

• ProcessPolicy_Rest_Json
