Performance testing, tuning, and scaling guidelines

Before any payment processing solution is deployed to production, it is essential that testing is performed to can ensure that performance requirements have been met. The goal of performance testing is to ensure that the target system can reliably process the loads that are required and to identify the deployment topology and configuration required.

Performance is dependent on infrastructure, environment, process, and the load being presented to the solution. Accordingly, each aspect of the solution needs to be monitored, tuned and configured. To help identify bottlenecks, it is important to monitor each part of the solution and collect suitable metrics. This can be achieved through various tools or through an enterprise observability platform such as Instana.
