How many relays does Trend Micro recommend for redundancy?

Trend Micro recommends a redundancy of two relays to ensure optimal performance and reliability in their security architecture. This configuration allows for load balancing and failover capabilities. By having a second relay, the system can maintain continuous operation even in the event of a relay failure or maintenance needs.

Two relays provide a sufficient level of redundancy without unnecessarily complicating the system architecture. This setup ensures that the data processing load can be distributed, thus improving efficiency. While having one relay may work for basic operations, it lacks the necessary resilience to prevent single points of failure. More than two relays could provide additional redundancy, but typically this leads to diminishing returns and added complexity in management and maintenance. Therefore, two relays are seen as the most effective and practical recommendation for redundancy in Trend Micro’s systems.
