There are many available off-the-shelf devices and services to connect everyday objects to the cloud and to each other. These range from industrial, large-scale applications, to small hobbyist options for the DIY community.
This market is just beginning to emerge and is highly competitive right now. Most of the devices have an approachable price, depending upon the applications for which they are intended. On the other hand, many of these devices are relatively new or are still going through their testing stages before entering the manufacturing process. This can give many people the perfect opportunity to get involved and participate in the beta and alpha testing stages.
For example, iOTOS is offering a university program in which iOTOS will give participants a NiO platform and an Arduino bridge for free. All it takes is a creative idea, a two-minute video of your project when completed, and a report of any bugs that are found (if any).
Since these devices are now just beginning to hit the market, it is probably going to result in a boom of connected devices very soon. Other than companies developing connected products, hackers are going to be connecting everything possible and possibly creating innovations of their own.
This is an exciting time in the development community, and I encourage everyone to join in and try your hand at connecting everyday devices to the Internet. Redesigning the wheel is not the design model anymore.
