Installing Software AG Products On Premises document provides the minimum system requirements to run API Gateway. These configurations change based on the production needs.

This section provides the hardware and product configuration guidelines that are required to setup API Gateway to run at an optimal scale. The hardware and product configuration guidelines are proposed for the following deployment architecture.

As an alternative for Apache Ignite, Terracotta Server Array can be used to set up a cluster. For more information about the cluster deployment, see Cluster Deployment. This is one of the architectures that is driven by availability and throughput factors. For information about the other variants of deployment architectures that is influenced by security, see Paired Deployment.

Typically, the parameters that influence the deployment architecture and the configurations are high availability, transactions per second (TPS), data volume, security requirements and so on. The hardware and product configurations that are recommended in this chapter are tested for the following throughput values. Consider the recommended hardware and product configurations as an outcome of a case study and not an official bench marking guide.

It is important to have the right sizing for the following components of API Gateway to meet the desired throughput requirements.

As Apache Ignite component is embedded into API Gateway, it does not require any dedicated sizing or configuration.

Apart from the sizing and configurations, to ensure high availability and optimal performance of API Gateway, it is also important to employ good data housekeeping, monitoring and other operational best practices. For details about Data housekeeping and Monitoring, see Data Management, Monitoring API Gateway. Additionally, it is important to consider the scaling options when there is an additional load on the system. Scaling is primarily influenced by two factors, load or TPS, and data volume. Hence, the components that are impacted for scaling are API Gateway and API Data Store respectively. For details about scaling, see Scaling.
