Best IOT Platform for Particle Electron?

Hey, I just got my Particle Electron and was wondering what in your opinion is the best IOT platform for this device such as Amazon, Azure, etc.

Any advice is appreciated.

This depends what you want to do with it, what features you’ll be looking for/using most, if and how much you want to pay, …

We basically need data analyzed from sonar range sensors then displayed on a web page.

Are they going to be battery powered or ? This is important to consider, depending on whether you will push data or pull data from the device.

They will be battery powered.
