The Microsoft Office Web Applications that were once configured and managed as a service application in SharePoint 2010 are configured and managed completely different in SharePoint 2013. The Office Web Applications (OWA) are now created in an Office Web Apps farm, which allows you to create a universal Office Web App environment that can host multiple SharePoint farms, as well as communicate with Lync and Exchange servers. The OWA farm allows users to create, edit, and share content using browser-based versions of Word, Excel, PowerPoint, and OneNote. Furthermore, OWA can be configured to enhance the users search experience by providing a document preview or thumbnail that is viewable from within the search result set. This session will discuss how and why you will want to implement the new Office Web Apps and the many benefits of doing so.

12. What’s New with OWA and SharePoint 2013

13. OWA Terminology
 WOPI Protocol = Web application Open Platform Interface
 Office Webs Contain Two Components
 WOPI Apps or Clients – (OWA Servers to Render Documents – Called WAC - Web
Application Companions)
 WOPI Host or WOPI Servers – SharePoint, Lync, or Exchange Hosting Documents

14.  Types of OWA Server Roles in Load Balanced Environment
 Front End
