ID systems are built on strong IT infrastructure, including computing resources, hardware, applications, network and server architecture, and more. The IT architecture that knits all these technologies together is a critical determining factor of the reliability, security, and flexibility, with major implications for program cost, sustainability, suitability for different use cases, the ability to protect personal data, and the adaptability of the system over time.
Devising an IT architecture that balances all these factors effectively is a major undertaking, requiring expert input from technologists, ID practitioners, and other stakeholders. This Guide cannot consider every factor in detail or provide a formulat for determining the correct architectural choices. Rather, this section attempts to present an overview of key decisions that practitioner’s should be prepared to take in respect to:
