With SharePoint 2010 around the corner, I thought I’d provide a brief overview of the NEW Shared Service model. That is, how the Shared Service Provider (SSP) from SharePoint 2007 has fundamentally changed for SharePoint 2010.
So, what’s this “Service” thing you’re on about?
Well, officially, in SharePoint 2010 terms, a Service is a “middle tier feature that performs the useful function of providing Data or Processing resources and is used by SharePoint features” – nothing new or surprising here then, but worth clarifying I think. There are however some exciting changes in the way such Services are structured, as discussed below.
SharePoint 2010 Shared Service Changes
Firstly, and very importantly, SSPs are gone. The reasons for this include (a) SSPs grouped items that were not necessarily similar, (b) in SharePoint 2007, some users found it hard to deploy and manage SSP’s, (c) SSP’s didn’t necessarily scale to the nth degree (too many services in one DB)
So, what’s replaced the SSP I hear you cry? Well, the new SP2010 concept is “Service Application” or “Service App”, where SSP Services are split out into separate services, for example:
There are a whole host of Service Apps present, but the general idea is that you have an App for each Service, rather than one App with lots of Services crammed into it. The Services, as before, will be managed via Central Admin. The new model can be illustrated well in a diagram, just like the one below:
From the above diagram, you can see many of the benefits the new Service Model provides; amongst other things it allows:
Secondly, some of the services also have their own database, rather than a shared database, like in SP2007. The following services are examples of services that have their own database:
Thirdly, with this new Service model comes some new terms, all of which I’m sure will be used heavily in the next few months. I thought I’d put them out there so everyone knows what they are and can skill up ahead of their colleagues!:
What Service apps are NEW then, and what do they actually do?
You’ve seen from the above that the architecture has been modified and they are lots of NEW Services available in SharePoint 2010. I’ve provided a brief list of some of the new Services and what they do below:
For more new services info and to get your hands dirty (as it were), I’d encourage you to keep an eye on this blog.
