Office Web Apps was introduced with SharePoint 2010 as a service used to provide browser-based access to Office documents. Office Web Apps (OWA) 2013 modifies the service architecture significantly, enabling the exposure of document interactions through a browser to be customized and expanded within SharePoint as well as outside of SharePoint. With this architecture change, we need to review the capabilities from a new perspective and question how we can best leverage this service. To start, we need to understand the new architecture changes. From there, how do we manage the health of OWA and apply updates? How do we leverage OWA to build additional capabilities into our applications? How do we expand OWA capabilities? What are the differences in OWA on-prem and OWA Office 365? In this session, we'll be answering these questions and more. We'll look at the new 2013 architecture and understand how to deploy the service on-prem and manage it properly. We will then look at how to extend the service and take advantage of the new capabilities in both our SharePoint and non-SharePoint solutions. You'll leave the session with a deeper understanding of OWA capabilities, and ready to incorporate OWA into your solution architectures!

- 28. Applying Patches & Updates • Standard MSI patching • Server has to be disconnected from farm to be able to patch it • Use PowerShell - Remove-OfficeWebAppsMachine / New-OfficeWebAppsMachine • In place major version upgrades are not supported • Previous Office Web Apps Server installation has to be removed before new version can be installed • Schema will be kept intact within major version, but not necessarily with cross major versions • Upgraded Office Web Apps server will work with older WOPI host

- 35. Custom WOPI Client Use our OWA farm to display non-Office documents 1. Discovery XML used when WOPI binding created from the host 1. Defines our Apps and Actions 2. Create the viewer page (aspx) 3. Deploy (e.g. Simple IIS website) 4. Bind from WOPI host (New-SPWOPIBinding)

Editor's Notes
- Business model of mobile staff and BYOD
- OWA is not Outlook Web Access, used by ExchangeSimply stated, view or edit a document in the browser
- OWA
- Excel Services
- Can use one or the other, set by New-SPWOPISuppressionSetting, not both

- This slide is explaining how to perform Office Web App level patching with minimal or no-downtime. Since Office Web Apps implementation is basically stateless, we can move the traffic between old and new versions of the farm. <click>So – what we first need is to have clear plan on what needs to be performed for OS and for Office Web Apps. Having that documented and obviously tested before starting to perform these steps in production.<click>We first take away one of the existing servers from Office Web Apps farm and path that with latest patches. When server is removed from the Office Web Apps farm, we update the NBL pools as well to ensure that there’s no end user traffic landing on this server, until it’s patched.<click>Then we create completely new office Web Apps farm using that particular server by running the New-OfficeWebAppFarm command<click>After that we’ll take following server from the farm, patch it and move it over to newly created patched farm and update the NLB accordingly<click>When we have enough servers patched, we can then move the traffic from NLB to point on the new patched farm. This will basically redirect all new requests coming to Office Web Apps farm to new patched environment. Since Office Web Apps is basically stateless, there’s really no implications for the end users. When requests are landing to new farm, they will just re-convert the Office documents what are being viewed to browser format and they will server the content properly. Starting from this moment, we are serving content using the patched farm.<click>Then we patch the existing servers and move the over one-by-one<click>Until we have final server left, where we can then delete the old farm and move that one over to the new farm side and we have patched then whole farm. Then when there’s again requirements to patch the server, either OS or Office Web Apps, we can perform the same process again. Key point here is to notice that we were able to patch and update the farm without any service breaks. There could have been some slowness during the process for the end users, but still the service it self was up and running without actual breaks. Obviously this means some coordination and strict process to follow, but due the simplicity of the Office Web Apps infrastructure, we can achieve this relatively easily.
