4.1.2 Use Case
An organization administrator is setting up a simple n-tier application comprised of front end Web servers and back end database servers. For high availability and scaling, the administrator wants to load balance these Web servers. The administrator wants to avoid using in-guest techniques and does not want to deploy additional virtual machines to deliver this load balancing service because of the burden of having to manage additional infrastructure workloads. The administrator has decided to use the out-of-the-box load balancing service provided by the Edge Gateway as the easiest way to meet these needs. The administrator wants to use public IP addresses to be able to define a virtual IP that balances (round-robin) two Web servers that are instantiated in an organization.
