It offers considerably more insight into the health of the servers without sacrificing security. This is especially true because my lab is a single subnet so I will be using a one-arm configuration for my load balancer. All clients, servers and the load balancer will sit on the same subnet. It also suggests a Service Name. You can make the service name whatever you desire.
Based on our environment diagram this will be Once complete click Add this Virtual Service. This brings us to the properties screen for the virtual service.
This is where the awesome sauce of the template really kicks in. In addition, this template has configured our SSL acceleration settings and a port 80 redirect. All the SSL TLS processing and management overhead can be centralized on LoadMaster improving the performance of front-end servers and simplifying the management of private keys and certificates.
All LoadMaster models have SSL offload capability with some of the hardware models incorporating dedicated SSL acceleration hardware for improving Exchange performance. As a Microsoft approved solution for load balancing OWA, LoadMaster includes proven templates that simplify the deployment of Exchange services that are hosted across multiple front-end servers.

Figure 1: Example request for a client accessing Exchange The new simplified infrastructure provides us the opportunity to make load balancing as simple as it possibly can — if desired, we can use DNS round robin , a technique that simply provides the client with the IP address of every mailbox server, and let the HTTP client do the rest.
If one Exchange server fails completely, then the protocol is smart enough to attempt connection to another server. There are a number of downsides to DNS round robin. It is not actually load balancing the traffic and there are no guarantees that each server will receive its fair share. It also has no service level monitoring, meaning that if a single service is failed, for example Outlook on the web, clients will simply see the error page rather than be automatically directed to another server.
Finally it requires more external IP addresses when publishing externally, as each individual Exchange server will require an external IP address.
These reasons typically mean that a load balancer is very desirable when publishing Exchange to clients. We will want a load balancer to monitor each Exchange client facing service and if a failure does occur, direct traffic to another server and take that service offline. We will also want the load balancer to perform some level of distribution of load to ensure that one particular mailbox server is not proxying the majority of client access. When load balancing services using a load balancer we can utilize either Layer 4 or Layer 7 load balancing.
But as you may recall, back then TMG was not suited as a load balancer for internal clients accessing Exchange. TMG was a perimeter firewall. Exchange Server required session affinity a relationship between the client and a specific CAS server at the load balancing layer for most Exchange services, which meant that the load balancing solution needed to be configured using layer 7 based load balancing aka application-level load balancing.
With Exchange and onwards, session affinity is no longer required and RPC access from an Outlook desktop client to Exchange was removed. The same goes for Outlook clients connecting to mailboxes in Exchange Online. By moving away from RPC connections to Exchange and removing the session affinity overall, the load balancing aspects of deploying an Exchange server solution on-premises has become much simpler seen from the Exchange Server product perspective.It is an ideal choice for low traffic web sites and applications, DevOps testing environments, technical training environments, and for any other deployments that suit your non-commercial needs.
