  • Hi,

    Is there any bad implication, running multiple service apps in the same proxy group?

  • Hi spadminspadmin.

    A service application proxy group is just a mechanism which defines the relationship between a web application and the proxy (or connection) for a service application: as far as I know, there is no bad implication in having multiple service applications listed in the same proxy group.

    Bye.

  • could you please be more specific about your proxy group configuration, why do you think of this?

    A "proxy" group is just a way of conveniently grouping and specifying service application connections (proxies) to a web application. Rather than having to manually specify each service application connection to each web application, you only need to add all the service application connections to a group, and then associate that group with a web application and "voila", they are all connected. If your farm has multiple web applications and some of those web applications have a dedicated purpose, you can group service application connections in different ways that only deliver those services to web applications that are needed.  Here are key Microsoft quotes on this:

    When you create a service application in SharePoint Server, a service application connection is created. A service application connection is also referred to as an application proxy. A service application connection associates the service application to web applications via membership in a service application connection group (also referred to as application proxy group).
    By default, a new service application connection is added to the farm's Default group of service application connections when you create the service application by using Central Administration. You can override this default membership. If a new service application is created by using Microsoft PowerShell instead of by using Central Administration, the new service application does not automatically become a member of the Default service application connections group unless the default parameter is supplied.
    By default, all web applications are associated with the farm's Default group of service application connections, although you can change this setting. You can also create one custom connection group for each web application in the farm. You can change the service applications with which a web application is associated at any time, and you can change the service applications that are included in the Default service application connection group.
    Reference: Add or remove service application connections from a web application in SharePoint Server

    For example, you may have an internally-facing web application that you want to deliver most all services to, including: Visio, Business Data Connectivity, Access, User Profiles, and so on. So, you create a proxy group and add to that proxy group all of the connections (proxies) of those services that you want to make available to that web application. Another web application in your farm may be Internet-facing and providing resources to a business partner perhaps. You may not need to deliver such services to this partner website such as User Profiles, Visio, Access, Word Automation, etc, and so you create a proxy group and to that proxy group the connections to only those services you want to make available to that partner web application. You can see this in the Microsoft TechNet design sample diagram: Corporate Portal with Path-based Sites for SharePoint Server 2013.

    Once you have a proxy group configured, you can conveniently use it again for other web applications without having to make any changes. Connections used in one proxy group can be used in other proxy groups. Proxy groups can contain just one service application proxy or all of the available ones.  To learn more about proxy groups and their usage, check out the first three Microsoft TechNet references below.

  • Incidentally, what Luigi states,

    A service application proxy group is just a mechanism which defines the relationship between a web application and the proxy (or connection) for a service application: as far as I know, there is no bad implication in having multiple serviceapplications listed in the same proxy group.

    is almost an exact copy of the following:

    ...A Proxy Group is a mechanism which defines the relationship between a web application and the proxy (or connection) for a service application. This proxy enables the web applications associated with the Proxy Group to consume services (Managed Metadata, Search, User Profiles, etc.) from the service application...

    which was posted on the "What about SharePoint" blog on 9/10/2013, Proxy Groups in SharePoint 2013.   It's important to always properly attribute what one quotes from others and give credit where credit is due.
