[SM Instances] Scale in / out on demand #279

Closed anapolg closed 5 years ago

anapolg commented 5 years ago

Related to #282

After deactivating the enforced policy if any / From the beginning if no policy is enforced: A) The VNF instances will display a x or rubbish button to scale in. B) The VNF instances will also display a + button preceded by an input to include the number of scale out requests the user wants to do over a VNF.

Commented by @tsoenen in #248

On the subject of having a + and - sign next to VNFs to scale out / in:

The - sign doesn't really make sense, as you have to specify which VNF you want to remove for the scale in. It could be better to use a x sign next to each VNF to indicate this. Clicking the + sign multiple times results in individual scale-out requests with one instance. With some sort of input textbox next to the VNF, you could indicate how many you want to scale out.
