Which of the following is a recommended configuration for a small IdentityIQ implementation?

In a small IdentityIQ implementation, recommending the use of separate database and host servers is advantageous for a few reasons. This configuration helps ensure that the application server, responsible for running IdentityIQ and handling user requests, is decoupled from the database server, which stores all the critical data. By separating these components, you improve security by limiting the attack surface; if the application server is compromised, the database remains isolated and protected.

Additionally, having separate servers can lead to better performance since you can allocate specific resources to each server based on their distinct functions. The application server can be optimally configured to handle user transactions, while the database server can be optimized for data storage and retrieval without competing for resources. This setup enhances overall system reliability and scalability, allowing easier upgrades and maintenance for either component without affecting the other.

Configurations such as single application servers or shared database services present risks that may not align with best practices for data security and performance, especially as the number of users grows or when regulatory compliance becomes a concern. While dual firewalls add layers of security, they may not be strictly necessary for smaller setups compared to the benefits provided by using separate servers.
