Tom Nolle: Cloud Data: Big AND Persistent!

We always hear about "Big" data, but a real issue in cloud storage is not just bigness but also persistence. A large data model is less complicated than a big application repository that somehow needs to be accessed. The Hadoop send-program-to-data model may be the answer.

My pleasure; how are you using or planning for the combo if I may ask?

Great Video Tom,

I think that is safe to say that data will always be exponentially increasing, and thus access to that data at an acceptable speed is essential for maintain a business running.

I'm reminded of gmail, in the way that when you run a search, it can quickly retrieve an email much better than outlook, and yet maintain a high level of service.

Maybe there is something to be learn the way google manages this.

Re: Cloud Data Solutions
Thanks, Mejiac!  I think the Google example is a good one.  They were pioneers in big data and also in distributing data and query in a hierarchy (MapReduce, now available in OpenSource as Hadoop).  One thing I think is true is that organizing data for quick access is easiest if you have a notion of what the predominate access will be.  For example, textual search can be accelerated by doing some syntactical analysis while indexing and being sure to check nouns first.  There are some divisions in big data now, between object stores that store things with structured properties (emails) and file stores that hold arbitrary data models.

Re: Cloud Data Solutions

Hi Tom and thanks for the information regarding Big Data persistence and repositories - the physical separation of data and the user.  If I understood correctly you mentioned, a feature of Hadoop that would separate the application and just send the "pieces of the application" to the user ?  Isn't this somewhat similar to what Amazon is doing with their recent Marketplace offering ?

Tom Nolle   Cloud Data: Big AND Persistent!   4/22/2012 7:54:21 AM
Re: Cloud Data Solutions
I think there's a little difference, Technocrat.  Hadoop is based on the presumption that big data is distributed over many sites, and so it's designed for applications that can be decomposed and sent to where the needed data is hosted.  The results can be collected and joined at the control node.  What I think Amazon is doing with marketplace is recognizing the reality of the cloud, which is that SaaS is the best answer overall for users.  So they attract software vendors to host apps on their cloud rather than try to sell IaaS services to what's going to be a small subset of the overall cloud market.  I think the non-hosted software is more a pull to get marketplace traffic up than a commitment to a broader model, though I'm sure they're happy to link software sales in a traditional sense and SaaS sales.

Thanks for the clarification Tom, I understand the difference between the two much better now !  : )

Re: Cloud Data Solutions
Good, but we can all expect that this space is going to move forward two steps for every step that even the fastest of us can take!  We're in for a couple of years of classic catch-up ball, I'm afraid.  I know I'm scrambling.

Re: Cloud Data Solutions
Thank you Tom for the reply,

Do you think that further down the road, will data management become more complex? and hence, will security protocols require more robust solutions?
Tom Nolle   Cloud Data: Big AND Persistent!   4/22/2012 11:03:52 AM
Re: Cloud Data Solutions
Good questions!  I think the cloud is going to redefine a lot of things in IT, one of which is data management.  The good news is that it's also going to result in a lot of automated tools that help organize information for distributed access.  For bigger businesses these tools will likely create a kind of "neutralizing" of the added complexities.  For smaller businesses the tools might actually make things easier by automating more!
