Hello,

I have been reading MS VSTS and am getting a little confused on the LLD. If someone could provide a quick sample I would greatly appreciate it. I have two scenarios:

Scenario 1:

We have two physical boxes. 1) Database Server w2k3 2) IIS server w2k3. The IIS box has both the webservices as well as the web site application on the same box. What endpoints do I add? How can I represent this on an LLD?

Scenario 2:

On a client we have w2k machine. It has sql express as well as a vb.net windows application. Sql express will replicate via websync which is fired off from the vb.net windows application. What endpoints do I add? How can I represent this on an LLD?

If anyone could just provide a simple sample to these scenarios It would be a great starting point for me. Thanks in advance.

Brian,

Thanks for the response. For scenario 1 would I have two IISwebServers? Even though on the same box. One for the website and one for the webservice? What are the differences between a HTTPClientEndpoint and a WebSiteEndpoint? Would the website connect to the webservice via a WebSiteEndpoint and then a client connect to the website using the HTTPClientEndpoint?

An HTTPClientEndpoint represents an outgoing connection from a shape. Where a WebSiteEndpoint represents the incoming server side of the communication. So if I have an IISWebServer shape and it needs to communicate to a web service on a second IISWebServer shape I would add an HttpClientEndpoint to one of the IISWebServer shapes and then connect the HttpClientEndpoint to the WebSiteEndpoint on the second IISWebServer Shape.

The Introduction to Logical Datacenter Designer, Part 2 demonstrates something like this.

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvs05/html/datacenterdesigner2.asp

If you have a web server that will host ASP.Net applications and WebService application you can represent them as two IISWebServer shapes or a single shape. It is up to you on how you want to describe your data center. Remember the designer is a logical designer it does not represent physical boxes.

HI John,

The post at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=5261&SiteID=1 links to a set of samples we shipped for Team Architect. Within this is a sample logical datacenter diagram. We also have some LDD-specific walkthroughs at http://msdn2.microsoft.com/library/ms246202(en-US,VS.80).aspx

Hi Brian / Elona (and John),

I'm interested in how to advise people who want to -- or are used to -- representing "physical" nodes (a la UML deployment diagram) rather than logical servers.

Would you say that's out of the question on the LDD since it's intended to be purely logical, or could we use zones for that purpose? So, two logical servers (s1 and s2) sitting on the same physical machine (wks1) would be placed in a zone named "wks1" representing that machine. I already use zones to represent network regions (e.g. DMZ, Public Internet zone etc.) and it seems not that different for zones to represent machines. What do you think?

Hi Tony,

Yes, you can use the zone to indicate that. Here's a help topic that discusses this scenario. http://msdn2.microsoft.com/ms242858(en-US,VS.80).aspx
