What is a Service Application?SharePoint Service: The middle tier .NET

component (Actual binary) that provides Data or Processing resources to SharePoint features.Service Instances: Running physical instance of a service.Service Application: A configured logical instance of a Service.

Provides data or computing resources according to the configuration.Exposes administrative interfaces (Web-based or PowerShell)Uses resources

One or more Service Databases.Application Pool

Service Applications vs SSPNo longer a separate SSP web site

SA’s managed via central admin

Pick and choose your service apps (SA)

If you don’t need a service app, don’t add it

Web apps can consume SAs on an individual basis

Each web app can use any combination of all available SA’s

Deploy multiple instances of the same SA

Just give each one a unique name

Reuse SA instances across multiple web apps in farm

Scaling Service Applications

Service Apps can achieve high scaleSelect which servers in the farm the SA runs on

Controlled in Services on Server page

Search Service Application is unique in how its topology is managedTo achieve more scale:

Add more serversConfigure SA’s to run on them

Cross Farm SAsCross Farm SAs

Any farm can publish SAs.Remote farms don’t need perms to parent farm DBs avoiding potential security issues.One web app can use both local and remote SAsProvides for centralized “enterprise” SAsNot all SAs can be shared between farms

Some Service AppsAccess Services

Allows viewing, editing, and interacting with Access databases in a browser.

Business Data Connectivity ServiceEnabling this service provides the SharePoint farm with the ability to upload BDC models that describe the interfaces of your enterprises’ line of business systems and thereby access the data within these systems.

Excel ServicesAllows viewing and interactivity with Excel files in a browser.

Managed Metadata ServiceProvides access to managed taxonomy hierarchies, keywords and social tagging infrastructure as well as Content Type publishing across site collections.

PerformancePoint Service ApplicationSupports the monitoring and analytic capabilities of PerformancePoint Services such as the storage and publication of dashboards and related content.

PowerPoint Service ApplicationEnables the viewing, editing and broadcast of PowerPoint presentations in a web browser.

Some Service Apps (cont.)Search Service Application

Index content and serve search queries. Usage and Health data collection

This service collects farm wide usage and health data and provides the ability to view various usage and health reports.

User Profile Service ApplicationAdds support for My Sites, Profile pages, Social Tagging and other social computing features. Some of the features offered by this service require Search Service Application and Managed Metadata Services to be provisioned.

Visio Graphics ServiceEnables viewing and refreshing of Visio web diagrams.

Web Analytics Service ApplicationEnable rich insights into web usage patterns by processing and analyzing web analytics data .

SA Proxies

A proxy is automatically created for an SA when the SA is created via central admin.It’s a virtual link that lives on WFE and used to connect web apps to Sas.

SA Proxy Groups

A proxy group is a group of SA proxies that are selected for a web appBy default, all SA proxies are included in the default proxy group.

You can remove them.A single proxy can be in multiple Proxy Groups

When you create a web app you can:select the default proxy groupcreate a custom proxy group by selecting which SA proxies should be included

The custom proxy group for one web app cannot be reused with a different web app

Changing the Default Proxy Group

Admin UI:Application Management <click>Configure service application associations <click> “default” (under “Proxy Group”) <click>

PowerShellGet-SPServiceApplicationProxy lists the SA proxy IDsAdd- and Remove-SPServiceApplicationProxyGroupMember takes the ID as a parameter

NOTE: Do NOT enter a name for the “Identity” parameter in these calls; just press Enter and when prompted and it will use the Default proxy group automatically

Associating Web Apps to Proxy Groups

Deploying and Managing SAs

Creating:Select services while running the farm Config Wizard Add services one by one on the Manage Service Applications page in Central AdminUse PowerShell

Managing:Central Admin, Manage Service Applications

Click on any SA and then the Manage button on the ribbonUse PowerShell

Some PowerShell examples:http://sharepoint.microsoft.com/blogs/zach/Lists/Posts/Post.aspx?ID=50

Developing Custom SAs

Creating custom SAs is possibleThe object model and interfaces have been defined so they act, look and feel like an out of the box serviceThere is a whitepaper available that outlines the basic concepts and relevant APIs

Multi-Tenancy (Partitioned and Non-partitioned Services)

Services can be configured to “share” data across Tenants or to “partition” data for each tenant (data isolation)

Allows multiple organizations to be ‘hosted’ on the same SharePoint configuration, but keeps their data isolated

Configurable ‘per-service’ to allow for “Mixed-Mode Partitioning”

Service Applications that support Multi-Tenancy can be administrated out of Central Administration (Delegated down to tenant admin site).
