Platform

WHAT IS A SERVICE PLATFORM

It provide facilities for application design, application development, testing, deployment and hosting as well as application services such as team collaboration, web service integration and marshaling, database integration, security, scalability, storage, persistence, state management, application versioning, application instrumentation

APPROACH

WHAT WE NORMALLY FORGET DURING TRADITIONAL APPROACH • Governance

• End user empowerment

• Security

• Hosting

• Consumption

• System Integrity across enterprise

SERVICES PLATFORM PROVIDES • SP can a number of benefits to an organization including software reuse, better alignment

with business processes and lower cost and agile development cycles. However, achieving these benefits requires building on top of a platform that provides a number of capabilities including:

• 1) Governance and Registry

• 2) Extension

• 3) Administration / Control

• 4) Security

• 5) Tooling

SO, WHAT WAS “BAD“ ABOUT SSP’S ?

SSP’s • Big improvement, but some limitations

All or nothing • Search / Profiles / Excel / BDC

Not extensible • No custom SSP

No granularity • Web application tied to specific SSPs

Sharing across farms • Tied to a single farm (shared-farm SSP’s possible but tricky)

ARCHITECTURE

1. Define the WCF endpoint2. Implement the business logic and package

(Maybe webservices, or windows services )3. Implement SAF 4. Create or reuse persistence store

ARCHITECTURAL VIEWService: Actual program (binaries)deployed to servers in farm

Service Application

Service Proxy Service Proxy

Web Part, Pages(Service

Consumer)

*.SVC’s, PowerShell Cmdlets

(Service Consumer)

Service Machine Instance: Actual instance of the running service binaries on a server

Service Application: Configuration of the servicein a farm

Service Application Proxy:Reference to the Service Application

Service Consumer: Bits that utilize the service’s logic

SERVICE APPLICATIONS (SP2010)

Flexibility • New services model much more flexible

A la carte • Just pick the one you need

Common Framework • Build custom using framework

Sharing • Single farm or shared across farms

Scalability • Entire farms can be dedicated to service hosting and computing

SERVICE APPLICATION FORMWORK • SAF is designed around an abstract model of service providers and consumers. This

abstract model provides the hooks that SharePoint uses to provide a unified management experience for a large variety of services

• Services that implement this model may be integrated with SharePoint features such as the Farm Configuration Wizard, the “Services on Server” and “Service Applications” management UX, and SharePoint backup/restore, to name a few.

• A middle-tier service is not part of a SharePoint web application or site, and is not directly accessed by end users. It is typically accessed from a Web Front End server (WFE) on behalf of an end-user request

• for example, the “Search Box” web part executing on a WFE invokes a middle-tier “Search Query” service application to retrieve raw search results, which are then rendered to HTML by the web part

SERVICE APPLICATIONS

SERVICES APPLICATION OBJECT MODEL

5 configuration object types: SPService, SPServiceInstance, SPServiceApplication, SPServiceProxy, and SPServiceApplicationProxy.

SPSERVICE (SERVICE)• The SPService class represents a service that has been registered in a SharePoint

server farm.

SPSERVICEINSTANCE (SERVICE INSTANCE)• The SPServiceInstance class represents a service (SPService) that has been installed

(but not necessarily started) on a specific application server (SPServer) in a SharePoint server farm. An SPServiceInstance has a Status property that indicates whether or not the service instance has been started.

SPSERVICEAPPLICATION (SERVICE APPLICATION)• The SPServiceApplication class represents a logical service endpoint (to which a service

consumer connects).

• This endpoint may actually consist of many physical endpoints; that is, the service application may be hosted on many application servers for additional reliability and scalability. These physical endpoints are represented by online (started) SPServiceInstance objects.

SPSERVICEPROXY (SERVICE PROXY)• The SPServiceProxy class represents a service consumer (client) that has been

registered in a SharePoint server farm.

• A custom SPServiceProxy may be installed by a SharePoint solution or a custom MSI, and registered when a server farm administrator activates a SharePoint farm-scoped feature or executes a PowerShell script.

SPSERVICEAPPLICATIONPROXY (SERVICE APPLICATION PROXY)• The SPServiceApplicationProxy class represents a logical connection to a service

application.
