In 9.3.1 we have tool to install multiple ArcGIS server instance by using AddInstance.exe. If we are able to do the similar thing in 10.1, How can we perform this.
What are the advantages/disadvantages in running 2 instances?
If I want to configure my Dev Server for diffrent projects( Proj X, Proj Y). The users working for Proj X can Publish/Read/View only their Proj X related services in Manager when they login. Similarly for Proj Y.
Please provide the required solution and information.
In 10.1, there is no instance concept. The closest you can get is to use the Web Adaptor component which can be installed separately. It will provide an entry point for your GIS Server requests. You can have multiple web adaptors installed on the same machine (i.e., web site) or on different web sites on the same machine. By providing different names to the web adaptor you give a unique way to access the system. Thereafter, you may secure your services much like you could with the 10.0 and earlier. Finally, if you want to limit access to certain services on certain machines, you might take a look at the clusters - another new concept in 10.1. Cluster is a way to group machines in a group on which certain GIS services will run.
