What is the best method of bringing Server and Farm information from the back-end to the client-side? For example, what if I wanted to do something like show the farm version on a SharePoint page? Or show the amount of memory on my web front-end server on a SharePoint page?
Is PowerShell possible here? I've read some things about SOAP and REST, where the former is falling by the wayside. Maybe Web services?
There's so much information out there and a lot of it is old. I'd like to know where to start looking into this from a 2015 going forward stand-point.
