Arduino and Internet Of Things: Good Cloud Service??

What is available for Hobbyist level creation of Internet Of Things with Arduino?

What Cloud services have you used, what looks good? I just got back to looking at this again and I’m confused!

Mango looked good until I realized it’s $400 after trial. I have an IBM “IBM Internet of Things Foundation” example running:
https://internetofthings.ibmcloud.com/dashboard/#/organizations/sdf0j2/devices
BUT it uses 98% of UNO Codespace! (With 1-wire temperature).

What about ThinkSpeak? Others? IsThere any online comparision of the possibilities?

I’d like to write a couple of clear How-To’s for ArduinoInfo.Info

Any comments, suggestions welcome!

I have been experementing a lot with data.sparkfun.com. i can run ok on their server, my own is much harder. you wont get much support from them.

Xively?

Exosite?

Grovestreams?
