Investments in payment systems architecture and supporting infrastructure are among the largest any organization makes. Proactively making such systems resilient to the multitude of causes that could render them unavailable — from component failure through natural disaster to security incident — maximizes the return on such investments. Doing so in a manner that closely aligns with proven practices of cloud-native design leverages the many supporting capabilities available in cloud service providers, helping to minimize cost while also reducing the number of supporting software components that need to be designed, built, and maintained. Cloud-native systems use automation not only for deployment but also for running daily operations. Automating to the same extent that production-ready systems are designed al- lows proper resource management and timely implementation of security patches. Terraform and Ansible are used in combination to build resilient cloud-native payment architectures. Terraform is applied for the deployment of the cloud-native payment architecture and the associated foundational infrastructure, while Ansible is used for the operational excellence aspects of the design. Terraform fulfills the Infrastructure as Code role, while Ansible provides orchestration and configuration management services and completes the continuous integration and continuous delivery pipeline. Cloud service provider support, cloud-native design, and automation in daily operations are primary pillars of the solution. The avoidance of service configuration details being directly embedded in Terraform modules enhances overall maintainability, flexibility, and compliance.Downloads
