Load balancing traffic has become a key aspect of many customer implementations as it distributes application requests and loads over multiple servers. It also provides a number of benefits to the overall topology including:
- Security. Logical isolation of the application servers is created or traffic requests denied based on IP protocols and port numbers.
- High-availability. Content is replicated to a pool, or group of servers, guaranteeing its availability to hosts.
- Scalability. Additional servers can be added as demand increases, enabling the load balancer to distribute the workload over the additional servers.
- Efficiency. Workloads are dynamically distributed when load balancing is configured. For example, resources like CPUs can be used in a more efficient ways.
