Question: Is there any way of creating a public folder calendar using the Exchange Management Shell?

Outlook is not installed on the Exchange Server nor do I want to install it. Access is very limited to client computers so I would rather create it from the server itself. Surely it can't be that difficult to do?

I have tried using the PFDAVAdmin tool but it fails to connect despite numerous attempts and I have given up on it for now.

Answer: 
That is correct. You can create the elastic load balancers and turn CloudWatch on for the instances using the GUI console, but to set up autoscaling config, groups, and triggers you have to use the [AutoScaling API tools](http://developer.amazonwebservices.com/connect/entry.jspa?externalID=2535&categoryID=88).

Your other option would be to use a third party provisioning vendor like [RightScale](http://www.rightscale.com/) that adds more GUI provisioning and scaling kinds of functionality.
To follow up on what Ernest said, it is indeed correct. Amazon autoscaling features works pretty well. But in order to use it you will need to do API calls.

However, if you want out-of-the-box autoscaling, you should consider using a third party cloud management platforms such as RightScale or [**Scalr**](http://scalr.net) (where I work). You will be able to scale based on CPU, Ram, Disk io, Network io... The autoscaling process itself is managed a bit differently. You can have more info on the [wiki](http://wiki.scalr.net/FAQ/Scalr_vs_AWS_auto-scaling).
