McCrory's Law: Data Gravity

Level 13

I was fortunate enough to be in the audience for my friend, Dave McCrory's presentation at Interop during the Future of Data Summit. Dave is currently the CTO of Basho, and he famously coined the term "data gravity" in 2010. Data gravity, or as friends have come to call it, McCrory's Law, simply states that data is attracted to data. Data now has such critical mass that processing is moving to it versus data moving to processing.

Furthermore, Dave introduced this notion of data agglomeration, where data will migrate to and stick with services that provide the best advantages. Examples of this concept include car dealerships and furniture stores being in the same vicinity, just as major cities of the world tend to be close to large bodies of water. In terms of cloud services, this is the reason why companies that incorporate weather readings are leveraging IBM Watson. IBM bought The Weather Company and all their IoT sensors, which has produced and continues to produce massive amounts of data.

I can't do enough justice to the quality of Dave's content and its context in our current hybrid IT world. His presentation was definitely worth the price of admission to Interop. Do you think data has gravity? Do you think data agglomeration will lead to multi-cloud service providers within an organization that is seeking competitive advantages?

Yes, the fish will school up in the big data lake!


Amazing (and creepy) how every little bit of every little thing gets logged somewhere and it all interconnects...

Level 15

That is true that it is all becoming completely interconnected.

Level 21

Definitely creepy.  As in Matthew 10:29's " . . . not a single sparrow can fall to the ground without your Father knowing it."  Definitely data management on a BIG scale.

Similarly, as the ISP's collect and sell your web surfing & searching history to advertisers, to the government, to your neighbors . . .  It just doesn't quite seem like the right to privacy is well-served with that bit of legislation that seeks profit first and foremost at the individual's cost.

At a time when it's popular to dis the "big guys" we all tend to gravitate to them. Of course not everyone falls into this, but we all know people that "hate" Microsoft, but wouldn't even consider Apple or Linux. Those that "hate" google, but are all to happy to buy an android phone and use a gmail account.

This made me think about all the calculations going on today to plan for new space missions around the moon for some reason lol:

Lunar Tourism and moon surface missions!

I do think data has gravity. And I think its own gravity can have a dramatic influence that will impact current and future data of the same type. Real-time decision-making... Here is an, admittedly, weak example:

Between Baltimore and DC there are four major thoroughfares: I-95, B/W Pkwy, Rte. 1 ("What Hath God Wrought"), and Rte. 29 ("Our D-Day Heroes!"). For speed an accessibility purposes, traffic notwithstanding, they should be used in this order: I-95, B/W Pkwy, Rte. 29, Rte. 1. Every evening at rush hour these roads have heavy traffic. Before internet your source for delays was radio and "updates" every 20 minutes, and even then those "updates" were usually based on data 30 - 60 minutes behind. Now with internet data is real-time so people can make decisions quickly when there are delays. However, with everyone receiving this data at the same time the drivers divert and the other routes quickly become flooded. Sometimes it just makes sense to stay on the road you are on while all the other drivers react to the data and clear out the road you're driving.  :-)

At one time we all wanted to get off the "Mainframe" and do our own thing.  Then one day someone had a bright idea to network all those stand alone  workstations together so we could house our file on a shared server so everyone could interact with those files.  Now we are migrating to a cloud.  It's all a circle of time. 

Level 21

I certainly think Dave is on to something here.  I think one of the next being things we will see (or actually already are seeing) is cloud service providers racing to provider more data based services.  Many of the cloud based services are mature at this point, I think data management and reporting frameworks (for lack of better term) are the next big thing.  Frameworks that let you extrapolate better insights out of your data for faster troubleshooting, better business decision making, etc.

If Data attracts Data and Moore's Law states the number of transistors per square inch has since doubled approximately every 18 months, along with the fact that we (humans) are generating so much data (communications, pictures, social media, and such) that we will never get rid of it seems likely the ISPs will move toward being Cloud SPs to store our data (20-30% we may actually use). 

Level 14


The more we collect ... the more we need.... the more we collect....

The perfect circle!

Level 15

Awesome description!!!!!

Level 13

for us non-public-cloud adopters, there are advantages to storing data in multiple locations (as anyone with 1/2 an I.T. brain knows). It would be interesting to see if anyone can come up with a RAID5 cloud solution to reduce the cost per location...
