In the PCE architecture, which component supports optimizing policy calculations?

The Memcached component in the PCE architecture plays a crucial role in optimizing policy calculations. It serves as an in-memory caching system that allows the Policy Compute Engine (PCE) to store and retrieve data quickly. By caching frequently accessed data, the Memcached component reduces the need for repeated calculations and database accesses, thus speeding up the overall process of policy optimization and enforcement.

This efficiency is especially important in environments with dynamic workloads and numerous policy updates, where quick access to policy information can significantly enhance performance. Utilizing caching mechanisms such as Memcached allows the PCE to maintain operational efficiency and agility, ensuring that security policies can adapt rapidly to changing conditions without compromising on responsiveness.

In contrast, options that include the Persistence Tier, Set server component, and Agent traffic cache serve different functions within the PCE architecture, such as data storage or traffic management, but do not specifically focus on optimizing policy calculations like Memcached does.
