Ứng dụng dịch vụ Ngoài ra thú vị khác là ứng dụng dịch vụ SharePoint. Nếu bạn đã sử dụng MOSS 2007, sau đó bạn có thể quen với dịch vụ chia sẻ kiến trúc của nó (SSP) cung cấp. Các SSP là một dịch vụ trung tâm là chia sẻ nguồn tài nguyên chung với một hoặc nhiều ứng dụng web. Điều này cho phép SharePoint để thực hiện một trong thu thập dữ liệu, ví dụ, nhưng cung cấp các chức năng tìm kiếm cho tất cả các ứng dụng web trong trang trại mà không nhân đôi nỗ. | Service Applications 7 FIGURE 1-3 SERVICE APPLICATIONS Another exciting addition to SharePoint is Service Applications. If you have used MOSS 2007 then you may be familiar with its Shared Service Provider SSP architecture. The SSP was a central service that shared common resources with one or many web applications. This enabled SharePoint to do one crawl for instance but provide the search functionality to all the web applications in the farm without duplicating effort. The SharePoint 2007 SSP was an all-or-nothing affair. Your web app could only be associated with a single SSP consuming all SSP services and it was difficult if not impossible to delegate authority over different parts of the SSP. Service Applications represent the evolution of the SSP. The SSP model had some pretty common pain points which the change to Service Applications addresses. In SharePoint 2010 all the Service Applications are separate. Examples of Service Applications include Search Profile Import Business Data Catalog and Managed Metadata. This means they can be turned on and off as needed enabling you to pick and choose only the ones you are actually using. This saves resources and reduces the attack vector. Service Applications can also be given their own permissions. This enables you to 8 CHAPTER 1 WHAT S NEW IN SHAREPOINT 2010 give one user the capability to manage Search without that user being able to do anything with the Managed Metadata Service. Central Administration is security trimmed so Service Application administrators will only see the Service Applications to which they have access. As an added bonus Service Applications are available in all versions of the product. Windows SharePoint Services did not have SSPs. They were only in the Search Server and MOSS SKUs of SharePoint 2007. In SharePoint 2010 all versions of the product benefit from Service Applications though different versions will have different Service Applications available. Chapter 7 covers Service .
