Skype For Windows Phone Will Stop Working in 2017 (betanews.com)
Mark Wilson, writing for BetaNews: With the release of Windows 10 Mobile, Microsoft's support for Windows Phone is gradually starting to die off. We already knew that Windows Phone support for Skype was coming to an end, but now we know more. Microsoft has now announced that as well as ending support for Skype on Windows Phone in October, come 'early 2017' the apps will simply stop working. And it's all thanks to a move to the cloud. The company has already said that the future of Skype is cloud-based rather than peer-to-peer, and this is the reason Windows Phone support is coming to a complete stop. Considering the amount of investment Microsoft has put into Skype, the decision to kill the app entirely is perhaps a little strange, but legacy support -- particularly for such a niche handset -- does not come cheap.
And if you supported Microsoft by buying Windows Phone, then Microsoft's message to you regarding your loyalty is clear.
No, it's in the cloud, duh! The place where magic happens. Lackluster apps turn into lackluster apps in the cloud, and stocks go up. Like a miracle. Or magnets.
"the future of Skype is cloud-based"
So it's client-server based?
Cloud is not a technical term. It describes no coherent system or network architecture.
All cloud means is you should expect to be mercilessly stalked and monetized while the voice of darth vader plays in a continuous loop "I am altering the deal. Pray I don't alter it any further".
Everything advertised as "cloud based" works this way.
