1 Sizing Methodology Overview

The Token Proxy Service is designed to provide a token exchange proxy service for hosted applications. A proxy interface works with your application to communicate with the payment service providers (PSP), on whom it relies to provide the actual token functionality. It connects to PSPs via the internet or virtual private network (VPN). The firewall should be configured to allow a connection from OPERA to TPS and from TPS to PSP for token exchange.

Token Proxy Service has the following three main components:

  • Token Proxy Service

  • Database

  • Token Proxy Web Portal

This benchmark is conducted using standard hardware with focus on the following Deployment types that fall in the critical path for application:

  1. Self-hosted on Single Machine/VM

  2. Self-hosted on Multiple Machine/VM
