Supported Office Web Apps Server Topologies

The actual process of integrating Office Web Apps Server and Lync Server 2013 is covered in Chapter 11, “Dependent Services and SQL.” This section provides a brief overview of how to plan for integration of your Office Web Apps Server installation with Lync Server 2013.

Option 1: Office Web Apps Server Installed On-premises in the Same Network Zone as Lync Server 2013

In this configuration, the Office Web Apps Server farm is installed on the organization’s network and ideally in the same network zone as the Lync Server. It is not a requirement for the server to be installed in the same network zone; however, this does reduce the administration overhead of configuring firewall rules and routing. With this topology, internal Lync clients connect to the Office Web Apps Server using an internally defined URL, and any external clients connect through the reverse proxy solution to an externally defined URL. This topology works best for organizations that are deploying a dedicated Office Web Apps Server farm for Lync Server 2013. Figure 19.4 shows how the topology would look.

Option 2: Office Web Apps Server Installed On-premises in the DMZ

Because Office Web Apps Server is able to provide services to Lync, Exchange, and SharePoint, some organizations might also choose to deploy this server in the DMZ. In this configuration both internal and external clients are routed through the reverse proxy server to access the Office Web Apps Server. This topology is ideal for organizations that are looking to deploy a shared Office Web Apps Server Farm for multiple server technologies. Figure 19.5 shows how this topology would look.

Option 3: Office Web Apps Server as a Hosted Service Outside the Internal Network

Office Web Apps Server can also be provided as a third-party hosted service. In this topology, Lync Server 2013 is deployed on-premises but uses an externally hosted Office Web Apps Server. Figure 19.6 shows how this topology would look.

Firewall requirements for all of these scenarios are outlined in Chapter 12, “Firewall and Security Requirements.” However, it is important for organizations that are planning an Office Web Apps Server deployment to take note that not only the Lync clients but also the Lync Front End server must be able to communicate with the Office Web Apps Server farm.
