Hopefully these should be a easy couple of questions. I've just recently got 2012 R2 installed and running. I've created a single Application to test with and it's been deployed which seems to add it to my ApplicationCatalog Site. I have over a thousand computers in the network so I wanted to make sure I understood how deployment works first before going live. I tested with Adobe Reader, creating my App. I also have created several user collections to test with. I followed a popular well known tutorial to get the basics and try and understand how deployment works. A few things I still can't seem to figure out.
1) When deploying a Application I was under the impression it would automatically install on the computers which are members of the Users Collection if they are logged into the computer. Is this the default deployment behavior? I've logged into a test computer and it doesn't seem to have installed automatically.
2) How do I deploy a application that only goes to the Application Catalog website but does NOT get deployed to my thousand PCs or in my case 2 computers in my test group? It might be that I have unknowingly done this already which is why it was not auto installed on my test PCs.
3) Whats the difference under Software > Applications and Packages? I can't really see one on the surface. I notice that tutorials show application upgrades via use of the Packages, but whats different? I setup Adobe under the Applications with my msi file.
