Today our on-going series on cloud computing continues with a brief discussion of data gravity and how it might impact cloud adoption.
Indeed, data gravity is yet another reason that the public cloud will not overtake all computing activity any time soon. Data gravity is the idea that data remains where it is and the applications and services are attracted to and use that data.
Moving data can be a tricky, time-consuming and complex process, even on-premises. Now add in the movement of large quantities of enterprise data through the Internet, to a cloud service provider. Anyone who has managed or used big data, or even moderately large data, will immediately recognize the problem.
Think about it. Sometimes even trying to email a large document doesn’t work, so you have to FTP it somewhere (e.g. Dropbox). And depending on the size of the document and the speed of your connection, it can take a while just to upload your one document. Now think of terabytes of enterprise data living on-premises at thousand of organizations across the globe. How long would it take to move all of that data?
If you have ever done any significant cloud development then you know that the initial load process for some cloud service providers involves shipping a server or storage devices to the customer that they load up and ship back. That is clearly not an ideal process…
So data gravity also will have an impact on cloud adoption rates.
