I was recently in a local computer / electronics store buying components for a new computer system I was building when I overheard another customer talking with the sales rep about a local storage device that he was looking to purchase and during the conversation he stated to the rep on the package it says “Cloud Compliant Whatever that means”. 
So that is the question what is Cloud Compliant? In this case it means that they storage drive is able to connect to a network and has the ability to access Cloud based services and applications which run over Internet network applications. To be compliant in this case the device is in accordance with established guidelines, specifications, or legislation for current Cloud systems.
So does this compliance make this device unique? The answer is both Yes and No. Yes that it can access to Cloud based service which is special in some ways however it is not the only type of device that can use or utilize Cloud services since many computers and cell phone along with other devices have the same ability.
The fact of the mater here is that because there is so much “Buzz” about Cloud’s and the services they can provide many companies are now putting on their boxes or descriptions that there devices are Cloud compliant as a marketing technique to help sell the device.
Many people that currently access the internet most likely access or used Cloud based services some great examples are Amazon which is one of the largest Cloud based providers currently providing services. Another is Google many of the services that Google now provides are actually Cloud based these days. These are just a couple of examples that most people currently use that are Cloud based technologies.
So basically when it comes down to it if you need a device that is going to access or take advantage of cloud based services then you might want one that is compliant with the Cloud but for most people it does not really matter that much since chances are that unless this is something special that might need or looking for from the device you want. Just keep in mind that for the most part that when you see Cloud compliant it is just a marketing technique since many devices can currently use and access Cloud based services.
