# Pool A Pool (also known as a Server Group) is a critical component in a Load Balancing system. It is responsible for distributing traffic to backend servers, improving the performance, availability, and reliability of your services. #### The Main Purpose of a Pool The primary goal of a Pool is load balancing. It ensures that incoming traffic is evenly and efficiently distributed across backend servers. This prevents any single server from becoming overloaded while others remain idle. #### Pool Components A Pool consists of backend servers, referred to as "Pool Members." These Pool Members serve requests and respond to users or devices through the Load Balancer. #### Related Topics Learn more about Pool Members and other Pool features through the following articles/guides: * **Pool Members** * **Pool's Algorithm** * **Add & Update a Pool** * **Configuring Health Check Settings** * **Enabling Sticky Sessions** * **Enabling TLS Encryption** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
