What is a best practice for on-premise deployment of VAs?

Deploying Virtual Appliances (VAs) near the authoritative source is a best practice because it significantly enhances performance by reducing latency. When VAs are located closer to the data they need to access, the time taken to communicate and retrieve information is minimized. This efficient access is crucial for real-time operations and ensures that identity governance and management processes run smoothly, maintaining overall system responsiveness.

Having VAs positioned in proximity to their data sources also allows for faster data synchronization and processing, which is essential for maintaining up-to-date identity information. This setup supports effective identity lifecycle management, access requests, and compliance initiatives by providing timely insights and enabling rapid responses to changes or issues.

Other options, while potentially relevant in specific scenarios, do not offer the same performance benefits that come from reduced latency. For example, isolating VAs in network segments or limiting their connectivity can lead to challenges in accessing necessary data, ultimately impairing their effectiveness in managing identity security.
