PROS Revenue Management Platform on AWS
Publication date: August 20, 2020 (Diagram history)
This reference architecture creates a highly available, secure, flexible, and cost-effective architecture on AWS. Use it to host a PROS application with two modules: Origin and Destination (O&D) and Group Revenue Management System (GRMS).
The PROS application manages revenue optimization for airlines. This architecture connects on-premises systems to AWS with redundant network paths. It provides automated failover for compute and database layers.

The following steps describe the architecture:
-
Connect on-premises users and systems through AWS Direct Connect as the primary connection. Use AWS Site-to-Site VPN as the secondary connection.
-
Use Amazon S3 for PROS applications to exchange files with upstream and downstream systems. Applications generate files after batch jobs and store them for retrieval.
-
The PROS application has an O&D module and a GRMS module. Access both modules only by private IP addresses. Connect Amazon VPCs (production and development) through AWS Transit Gateway.
-
The O&D module primary node distributes traffic and jobs to worker nodes. Configure manual failover to a worker node. You can also automate failover through an Auto Scaling group and script integration. For worker node failover, automate with CloudWatch and Lambda.
-
The GRMS module runs in active-passive mode. If the running Amazon EC2 instance fails, a new instance is provisioned. Automate failover through an Auto Scaling group.
-
Both O&D and GRMS use Amazon RDS for Oracle. Configure single-AZ (recovered from snapshot) or Multi-AZ (standby with failover). Use memory-optimized Amazon EC2 R5 instances for the O&D database.
-
AWS Key Management Service provides data-at-rest encryption at the database layer.
-
CloudWatch monitors the health of Amazon EC2 instances and Amazon RDS databases.
