System Requirements

Office Web Apps Server must be installed on a separate system in the environment, because it cannot be collocated with any of the Lync Server roles. High-availability is also supported for Office Web Apps Server and can be implemented via the installation of multiple servers and use of a hardware or software load-balancing solution. Whether a single system or multiple systems are deployed, each installation is referred to as an Office Web Apps Server farm. The following requirements and guidelines apply for systems used to host Office Web Apps Server:

• Supported operating systems are Windows Server 2008 R2 SP1 and Windows Server 2012.

• Minimum hardware requirements are 4 x 64-bit cores, 8GB RAM, 80GB system hard drive.
