Dana Gardner: Hello, and welcome to a special BriefingsDirect thought leadership interview series coming to you in conjunction with The Open Group Conference recently held in Newport Beach, California.

Gardner
I'm Dana Gardner, Principal Analyst at Interarbor Solutions, and I'll be your host and moderator throughout these business transformation discussions. The conference itself is focusing on "big data -- he transformation we need to embrace today." [Disclosure: The Open Group is a sponsor of this and other BriefingsDirect podcasts.]

We assembled a panel of experts to explore how big data changes the status quo for architecting the enterprise. We'll learn how large enterprises should anticipate the effects and impacts of big data, as well the simultaneous impacts of cloud computing and mobile.



It’s been an interesting thread throughout the conference for me to factor where big data begins and plain old data, if you will, ends. Of course, it's going to vary quite a bit from organization to organization.

But Chris Gerty from NASA provided a good example: It’s when you run out of gas with your old methods, and your ability to deal with the data -- and it's not just the size of the data itself.

When an enterprise architect and the business architect looked at data a few years ago, they might not have been as aware of these boundaries and the importance of data. They perhaps were thinking that the database administrators and the business intelligence (BI) folks would take care of that, and they just had to manage the fruits of the data vis-à-vis applications and integration points.

I don’t think that’s the case anymore, and one of the points we're going to get into now is where the enterprise architect needs to be factoring the impacts of big data.

Furthermore, there seems to be the need to do things differently, not just to manage the velocity and the volume and the variety of the data, but to really think about data fundamentally and differently. For many companies, data is now a product itself. That data can be monetized.

The analysis from the data becomes important to more and more people in the company, so that your employees, your partners, and those in your supply chain will be interacting with your data -- and the analysis from your data -- more than before.

So I think we need to also think about data differently. And, we need to think about security, risk and governance. If it's a "boundaryless organization" when it comes your data, either as a product or service or a resource, that control and management of which data should be exposed, which should be opened, and which should be very closely guarded all need to be factored, determined and implemented.

Expert panel

With that, let me now introduce our expert panel: Robert Weisman, CEO and Chief Enterprise Architect at Build The Vision; Andras Szakal, Vice President and CTO of IBM's Federal Division; Jim Hietala, Vice President for Security at The Open Group, and Chris Gerty, Deputy Program Manager at the Open Innovation Program at NASA.

Chris, let’s start with you. You mentioned that big data to you is not a factor of the size, because NASA's dealing with so much. It’s when you run out of steam, as it were, with the methodologies. Maybe you could explain more. When do you know that you've actually run out of steam with the methodologies?

Chris Gerty: When we collect data, we have some sort of goal in minds of what we might get out of it. When we put the pieces from the data together, it either maybe doesn't fit as well as you thought or you are successful and you continue to do the same thing, gathering archives of information.

Gerty
At that point, where you realize there might even something else that you want to do with the data, different than what you planned originally, that’s when we have to pivot a little bit and say, "Now I need to treat this as a living archive. It's a 'it may live beyond me' type of thing." At that point, I think you treat it as setting up the infrastructure for being used later, whether it’d be by you or someone else. That's an important transition to make and might be what one could define as big data.

Gardner: Andras, does that square with where you are in your government interactions -- that data now becomes a different type of resource, and when you are not able to execute or avail yourself of its value, then you know you need to do things differently?

Andras Szakal: The importance of data hasn’t changed. The data itself, the veracity of the data, is still important. Transactional data will always need to exist. The difference is that you have certainly the three or four Vs, depending on how you look at it, but the importance of data is in its veracity, and your ability to understand or to be able to use that data before the data's shelf life runs out.

Szakal
Some data has a shelf life that's long lived. Other data has very little shelf life, and you would use different approaches to being able to utilize that information. It's ultimately not about the data itself, but it’s about gaining deep insight into that data. So it’s not storing data or manipulating data, but applying those analytical capabilities to data.

Gardner: Bob, we've seen the price points on storage go down so dramatically. We've seem people just decide to hold on to data that they wouldn’t have before, simply because they can and they can afford to do so. That means we need to try to extract value and use that data. From the perspective of an enterprise architect, how are things different now, vis-à-vis this much larger set of data and variety of data, when it comes to planning and executing as architects?

Robert Weisman: One of the major issues is that normally organizations are holding two orders of magnitude more data then they need. It’s an huge overhead, both in terms of the applications architecture that has a code basis, larger than it should be, and also from the technology architecture that is supporting a horrendous number of servers and a whole bunch of technology stuff that they don't need.

The issue for the architect is to figure out as what data is useful, institute a governance process, so that you can have data lifecycle management, have a proper disposition,  focus the organization on information data and knowledge that is basically going to provide business value to the organization, and help them innovate and have a competitive advantage.

Can't afford it

And in terms of government, just improve service delivery, because there's waste right now on information infrastructure, and we can’t afford it anymore.

Gardner: I suppose big data is part of the problem, dealing with so much in redundancy and duplication through the lifecycle of data and what have you, but the data is also part of the solution in terms of getting the knowledge about what you should or shouldn't be doing as a business. So it's difficult to know what to keep and what not to keep.

I've actually spoken to a few people lately who want to keep everything, just because they want to mine it, and they are willing to spend the money and effort to do that. Jim Hietala, when people do get to this point of trying to decide what to keep, what not to keep, and how to architect properly for that, they also need to factor in security. It shouldn't become later in the process. It should come early. What are some of the precepts that you think are important in applying good security practices to big data?

Jim Hietala: One of the big challenges is that many of the big-data platforms weren’t built from the get-go with security in mind. So some of the controls that you've had available in your relational databases, for instance, you move over to the big data platforms and the access control authorizations and mechanisms are not there today.

Hietala
Planning the architecture, looking at bringing in third-party controls to give you the security mechanisms that you are used to in your older platforms, is something that organizations are going to have to do. It’s really an evolving and emerging thing at this point.

Gardner: There are a lot of unknown unknowns out there, as we discovered with our tweet chat last month. Some people think that the data is just data, and you apply the same security to it. Do you think that’s the case with big data? Is it just another follow-through of what you always did with data in the first place?

Hietala: I would say yes, at a conceptual level, but it's like what we saw with virtualization. When there was a mad rush to virtualize everything, many of those traditional security controls didn't translate directly into the virtualized world. The same thing is true with big data.

When you're talking about those volumes of data, applying encryption, applying various security controls, you have to think about how those things are going to scale? That may require new solutions from new technologies and that sort of thing.

Gardner: Chris Gerty, back to your experiences at NASA. You've taken the approach of keeping as much of that data and information as open as you can, fostering more research and the ability for people to do things with the data that you may never have been visioned yourselves. When it comes to that governance, security, and access control, are there any lessons that you've learned that you are aware of in terms of the best of openness, but also with the ability to manage the spigot?

Gerty: Spigot is probably a dangerous term to use, because it implies that all data is treated the same. The sooner that you can tag the data as either sensitive or not, mostly coming from the person or team that's developed or originated the data, the better.

Kicking the can

Once you have it on a hard drive, once you get crazy about storing everything, if you don't know where it came from, you're forced to put it into a secure environment. And that's just kicking the can down the road. It’s really a disservice to people who might use the data in a useful way to address their problems.

We constantly have satellites that are made for one purpose. They send all the data down. It’s controlled either for security or for intellectual property (IP), so someone can write a paper. Then, after the project doesn’t get funded or it just comes to a nice graceful close, there is that extra step, which is almost a responsibility of the originators, to make it useful to the rest of the world.

Gardner: Let’s look at big data through the lens of some other major trends right now. Let’s start with cloud. You mentioned that at NASA, you have your own private cloud that you're using a lot, of course, but you're also now dabbling in commercial and public clouds. Frankly, the price points that these cloud providers are offering for storage and data services are pretty compelling.

So we should expect more data to go to the cloud. Bob, from your perspective, as organizations and architects have to think about data in this hybrid cloud on-premises off-premises, moving back and forth, what do you think enterprise architects need to start thinking about in terms of managing that, planning for the right destination of data, based on the right mix of other requirements?

Weisman: It's a good question. As you said, the price point is compelling, but the security and privacy of the information is something else that has to be taken into account. Where is that information going to reside? You have to have very stringent service-level agreements (SLAs) and in certain cases, you might say it's a price point that’s compelling, but the risk analysis that I have done means that I'm going to have to set up my own private cloud.

Weisman
Right now, everybody's saying is the public cloud is going to be the way to go. Vendors are going to have to be very sensitive to that and many are, at this point in time, addressing a lot of the needs of some of the large client basis. So it’s not one-size-fits-all and it’s more than just a price for service. Architecture can bring down the price pretty dramatically, even within an enterprise.

Gardner: Andras, there's this mash up of cloud and big-data trends, the in-memory approaches, where we are no longer taking batches of data, cleansing it, and deduping it and bringing it into a warehouse, going through batch. We're still doing that' of course, but it seems that for a number of different applications of data and analytics, in-memory technology particularly, if you can control that in a cloud environment, private cloud or otherwise, it’s starting to change the game for that fast, real-time feedback loop benefit.

It's a roundabout way of asking if the cloud and big data come together in a way that’s intriguing to you and in what ways?

Szakal: Actually it’s a great question. We could take the rest of the 22 minutes talking on this one question. I helped lead the President’s Commission on big data that Steve Mills from IBM and -- I forget the name of the executive from SAP -- led. We intentionally tried to separate cloud from big data architecture, primarily because we don't believe that, in all cases, cloud is the answer to all things big data. You have to define the architecture that's appropriate for your business needs.

However, it also depends on where the data is born. Take many of the investments IBM has made into enterprise market management, for example, Coremetrics, several of these services that we now offer for helping customers understand deep insight into how their retail market or supply chain behaves.

Born in the cloud

All of that information is born in the cloud. But if you're talking about actually using cloud as infrastructure and moving around huge sums of data or constructing some of these solutions on your own, then some of the ideas that Bob conveyed are absolutely applicable.

I think it becomes prohibitive to do that and easier to stand up a hybrid environment for managing the amount of data. But I think that you have to think about whether your data is real-time data, whether it's data that you could apply some of these new technologies like Hadoop to, Hadoop MapReduce-type solutions, or whether it's traditional data warehousing.

Data warehouses are going to continue to exist and they're going to continue to evolve technologically. You're always going to use a subset of data in those data warehouses, and it's going to be an applicable technology for many years to come.

Gardner: So suffice it to say, an enterprise architect who is well versed in both cloud infrastructure requirements, technologies, and methods, as well as big data, will probably be in quite high demand. That specialization in one or the other isn’t as valuable as being able to cross-pollinate between them as it were.

Szakal: Absolutely. It's enabling our architects and finding deep individuals who have this unique set of skills, analytics, mathematics, and business. Those individuals are going to be the future architects of the IT world, because analytics and big data are going to be integrated into everything that we do and become part of the business processing.

Gardner: Well, that’s a great segue to the next topic that I am interested in, and it's around mobility as a trend and also application development. The reason I lump them together is that I increasingly see developers being tasked with mobile first.

When you create a new app, you have to remember that this is going to run in the mobile tier and you want to make sure that the requirements, the UI, and the complexity of that app don’t go beyond the ability of the mobile app and the mobile user. This is interesting to me, because data now has a different relationship with apps.

We used to think of apps as creating data and then the data would be stored and it might be used or integrated. Now, we have applications that are simply there in order to present the data and we have the ability now to present it to those mobile devices in the mobile tier, which means it goes anywhere, everywhere all the time.

Let me start with you Jim, because it’s security and risk, but it's also just rethinking the way we use data in a mobile tier. If we can do it safely, and that’s a big IF, how important should it be for organizations to start thinking about making this data available to all of these devices and just pour out into that mobile tier as possible?

Hietala: In terms of enabling the business, it’s very important. There are a lot of benefits that accrue from accessing your data from whatever device you happen to be on. To me, it is that question of "if," because now there’s a whole lot of problems to be solved relative to the data floating around anywhere on Android, iOS, whatever the platform is, and the organization being able to lock down their data on those devices, forgetting about whether it’s the organization device or my device. There’s a set of issues around that that the security industry is just starting to get their arms around today.

Mobile ability

Gardner: Chris, any thoughts about this mobile ability that the data gets more valuable the more you can use it and apply it, and then the more you can apply it, the more data you generate that makes the data more valuable, and we start getting into that positive feedback loop?

Gerty: Absolutely. It's almost an appreciation of what more people could do and get to the problem. We're getting to the point where, if it's available on your desktop, you’re going to find a way to make it available on your device.

That same security questions probably need to be answered anyway, but making it mobile compatible is almost an acknowledgment that there will be someone who wants to use it. So let me go that extra step to make it compatible and see what I get from them. It's more of a cultural benefit that you get from making things compatible with mobile.

Gardner: Any thoughts about what developers should be thinking by trying to bring the fruits of big data through these analytics to more users rather than just the BI folks or those that are good at SQL queries? Does this change the game by actually making an application on a mobile device, simple, powerful but accessing this real time updated treasure trove of data?

Gerty: I always think of the astronaut on the moon. He's got a big, bulky glove and he might have a heads-up display in front of him, but he really needs to know exactly a certain piece of information at the right moment, dealing with bandwidth issues, dealing with the environment, foggy helmet wherever.

It's very analogous to what the day-to-day professional will use trying to find out that quick e-mail he needs to know or which meeting to go to -- which one is more important -- and it all comes down to putting your developer in the shoes of the user. So anytime you can get interaction between the two, that’s valuable.

Gardner: Bob?

Weisman: From an enterprise architecture point of view my background is mainly defense and government, but defense mobile computing has been around for decades. So you've always been dealing with that.

The main thing is that in many cases, if they're coming up with information, the whole presentation layer is turning into another architecture domain with information visualization and also with your security controls, with an integrated identity management capability.

It's like you were saying about astronaut getting it right. He doesn't need to know everything that’s happening in the world. He needs to know about his heads-up display, the stuff that's relevant to him.

So it's getting the right information to person in an authorized manner, in a way that he can visualize and make sense of that information, be it straight data, analytics, or whatever. The presentation layer, ergonomics, visual communication are going to become very important in the future for that. There are also a lot of problems. Rather than doing it at the application level, you're doing it entirely in one layer.

Governance and security

Gardner: So clearly the implications of data are cutting across how we think about security, how we think about UI, how we factor in mobility. What we now think about in terms of governance and security, we have to do differently than we did with older data models.

Jim Hietala, what about the impact on spurring people towards more virtualized desktop delivery, if you don't want to have the date on that end device, if you want solve some of the issues about control and governance, and if you want to be able to manage just how much data gets into that UI, not too much not too little.

Do you think that some of these concerns that we’re addressing will push people to look even harder, maybe more aggressive in how they go to desktop and application virtualization, as they say, keep it on the server, deliver out just the deltas?

Hietala: That’s an interesting point. I’ve run across a startup in the last month or two that is doing is that. The whole value proposition is to virtualize the environment. You get virtual gold images. You don't have to worry about what's actually happening on the physical device and you know when the devices connect. The security threat goes away. So we may see more of that as a solution to that.

Gardner: Andras, do you see that that some of the implications of big data, far fetched as it may be, are propelling people to cultivate their servers more and virtualize their apps, their data, and their desktop right up to the end devices?

Szakal: Yeah, I do. I see IBM providing solutions for virtual desktop, but I think it was really a security question you were asking. You're certainly going to see an additional number of virtualized desktop environments.

Ultimately, our network still is not stable enough or at a high enough bandwidth to really make that useful exercise for all but the most menial users in the enterprise. From a security point of view, there is a lot to be still solved.

And part of the challenge in the cloud environment that we see today is the proliferation of virtual machines (VMs) and the inability to actually contain the security controls within those machines and across these machines from an enterprise perspective. So we're going to see more solutions proliferate in this area and to try to solve some of the management issues, as well as the security issues, but we're a long ways away from that.

Gardner: Okay, I am going to put you on the spot a little bit, because I want you to provide to us some examples of how you think big data is being used in a way that's fundamentally different than traditional data.

If you don't have permission to name these people don't, but you can just describe the use case. Let's just start with you Chris. You probably have quite a few in your own organization, but are there any ways that you're aware of that people are using big data that illustrate how fundamentally different and powerful this is going to be?

Most compelling

Gerty: We have several small projects that have come out of the events that we’ve worked on. The International Space Apps Challenge I mentioned before. These are mostly in the visualization realm, but it's the problems that go beyond those events that are really the most compelling. I’ll briefly touch on one.

A challenge that we’ve put out in the last Space Apps Challenge was to write an app that would allow someone to use NASA data to allow a farmer anywhere in the world to have an iPhone app or iPad app and say. "I live here. What should I grow? What could make me the most money and help my village the most?"

The team that worked on it quickly realized that even great satellite data didn't work for their application. There are too many other factors. There was the local economy, the runoff levels, and things that they just didn't have access to from the NASA data. So they decided that this was more than a just weekend project and they wanted to build that data set that they needed, so that they could finally make the product.

They found other collaboration mechanisms to continue the project after the Spaces Apps Challenge. They’ll be returning this year to the second one that we do in April with an entirely different view on the world, because they actually have some data sets now that they've been building up. They made some mechanism to capture it from the local environment.

Gardner: So that’s a great reminder that we’re not just talking about big data, but we’re talking about multiple big data and which ones you can pull together -- joined or otherwise -- to collate and produce big-data analysis results for something very, very interesting.

Gerty: Big data, by itself, isn't magical. It doesn't have the answers just by being big. If you need more, you need to pry deeper into it. That’s the example. They realized early enough that they were able to make something good.

Gardner: Chris, that’s a very good cause, but in a purely commercial sense, as we see more companies doing cloud ecosystem and partnership activities, when they start to share their data with that big "if" of secured and provisioned properly with other people in their markets, in their businesses, very powerful and interesting things can happen. Jim Hietala, any thoughts about examples that illustrate where we’re going and why this is so important.

Hietala: Being a security guy, I tend to talk about scare stories, horror stories. One example from last year that struck me. One of the major retailers here in the U.S. hit the news for having predicted, through customer purchase behavior, when people were pregnant.

They could look and see, based upon buying 20 things, that if you're buying 15 of these and your purchase behavior has changed, they can tell that. The privacy implications to that are somewhat concerning.

An example was that this retailer was sending out coupons related to somebody being pregnant. The teenage girl, who was pregnant hadn't told her family yet. The father found it. There was alarm in the household and at the local retailer store, when the father went and confronted them.

Privacy implications

There are privacy implications from the use of big data. When you get powerful new technology in marketing people's hands, things sometimes go awry. So I'd throw that out just as a cautionary tale that there is that aspect to this. When you can see across people's buying transactions, things like that, there are privacy considerations that we’ll have to think about, and that we really need to think about as an industry and a society.

Gardner: Just because you can do something, doesn't necessarily mean you should.

Allen Brown: Can I put some of the questions in and see how you can do with them? The first one is more of a bit of a security question, but also concerns things like thoughts on self-protecting data, like the Jericho Forum issues, and another one that says, in terms of security, that big data may not have strong confidentiality and availability requirements, but for collaboration, doesn't integrity nearly always need to considered. Other examples are that there is no integrity requirement.

Gardner: Jim, I think it’s best directed to you to start. These are issues about controlled managements. Any thoughts?

Hietala: I'll get straight to the integrity piece. The integrity of the data, whether it’s on older platforms or big data, is certainly an issue. When folks are using big data, that data has to have integrity, and there has to be adequate controls protect the data. So I think that is kind of a fundamental thing for big data as well.

Gardner: Anyone else on these issues of protection?

Gerty: It’s not only a matter of data protection. It's what we do with the data. Big data is a term that is kind of heading towards the end of its usefulness, because it's not the data and how large it is that's useful. It's actually how we apply these deep analytics solutions, for example Watson. You saw the Watson win on Jeopardy, but now Watson is a product that’s being used to help some customers diagnose disease and work with the insurance companies.

How you actually utilize that data to derive value through this deep analytics solution is through a new set of artificial-intelligence applications called cognitive computing. So cognitive computing, how you drive all of this information, and how you apply it in the context of its usefulness to privacy and security is going to be huge in the following years.

Gardner: Allen, other questions from the audience or online?

Brown: Interoperability is the focus of a couple of questions. One is asking if you can address the expected interoperability issues across semantics of big data. The other part of it asks what’s the unique challenge or problems that unstructured, big data from Twitter, Facebook, and so on present?

Gardner: This might be an area where the concepts work for traditional data, and it might still be the case that is we have to pull all these different data types, structured and unstructured, together to work in some holistic fashion. Bob, any thoughts about big data, correlating of different data is that different from the past? Is there something new?

Weisman: I'm looking at techniques that were pioneered 20-30 years ago on the artificial intelligence, knowledge base system side, and are still is relevant today. As a matter of fact they're more relevant than they've ever been. There is lot opportunity, but it doesn’t forego having a good interoperability architecture, understanding where your contacts are, and being able to integrate data. Right now most of analytics is kiboshed, because they spent all their time doing data integration, versus analytics, and it’s a great waste of a lot of people's times.

So if you architect this from the get-go, get the proper metadata, which will address some of the integrity, and understand the concept of data quality which is what’s coming through, that will go a long way to resolving some of these issues, but the architecture is going to be key, as is rigorous planning.

More usable

Gardner: Andras, same question. Is there something new or different about treating data in order to make it more useable?

Szakal: Big data is coming to us in all sorts of forms and formats. It’s coming from different sources. We don't really know the validity. The validity is determined by the application of the analytics solution. You'll have to have some internal process, some governance process, to determine whether you're getting the validity of the data that you expect.

When I was working as a graduate student for the psychology department as the SPSS programmer, people would bring their work to me. They would try to apply analytics to make any point they possibly could. It's the old story about making statistics mean anything you want. But you have to be very careful about how you do that, because it’s going to have a huge impact on your business.

Gardner: Jim, in the realm of privacy and security, any thoughts about what types of unstructured content you may or may not want to bring in? Is this something now that you need to consider, picking and choosing of data types with an overview or lens towards security and privacy issues?

Hietala: In terms of unstructured content, there’s a whole lot of work to be done there to understand the growth of that stuff in average enterprise and what's really in unstructured content stores. A lot of that is ending up in collaboration platforms today, and most organizations don’t have a great understanding of what’s really in there.

It’s the regulated data in there, sensitive data in there. That’s an area where there’s work to be done by most enterprises to understand that unstructured content and the risk that it represents to the business.

Gardner: We haven’t got into it,, but another factor is the whole social sphere of data, and information that is being generated constantly.

Brown: The next question is a concern about whether it's causing a disruption to object orientation. Object-oriented data is encapsulated by the application, and making big data shared seems to break this approach. What are your thoughts on that?

Gardner: All right, from an architectural standpoint we're treating data a little bit differently, separating it entirely from an application or service.

Hietala: We just did a study that of this exact same question and problem. We found that there's no official programming model of the big-data world or in the cloud, although it is all about the client and integration with services. But there are all sorts of programming models out there. I would say that you apply the one that’s got the best and most appropriate approach.

Information centric

Weisman: It’s starting to put the emphasis back on the information syllable and information technology. Object orientation was meant to basically support an information-centric approach, and now it’s being used much more as a service-centric approach. Now we’re going to go back to a much more information-centric, information-engineering approach and a lot of the architecture enabled by big data.

Gardner: Maybe you could just expand that a little bit for me? Does that mean we have a different type of application? That is to say that data is the application? What were the implications of what you just said?

Weisman: When object orientation first came out, the idea was to take the data and build services around it. Now, we have services that pass data back and forth. Most organizations have hundreds of applications with encapsulated data within them, and they can’t share it. Often the same information is found in hundreds of applications, which causes a huge security headache. Now we should be looking at getting much more information centric which is the core of information technology, information related technology.

Gardner: So really it's a flip architecturally, when you think about maintaining a pool resource of information, and applications are either newly built to expose and leverage, or all your existing applications also have to bring into and connect to and integrate. Fair enough?

Weisman: I think it’s a separation between process-centric services and information-centric services and harmonizing those. That will probably be the best bang for the buck.

Gardner: So now we're into IT transformation and business transformation, and you have to rethink your data center and your entire apparatus for supporting your storage. People are going to get into that anyway for some of the reasons we talked about, but again, we could look at big data and say this is an accelerator to some of those transformation efforts.

Brown: Something that has been troubling me is around the data architecture. Mike Walker, now at Dell, on the live stream, is asking what specific guidance and best practices can you give to enterprise data architects to properly architect their information architectures.

Weisman: We're talking that this afternoon. There’s going to be an entire track or two tracks on data architecture, which will be providing the guidance and it’s big-data centric.

Gerty: You're still going to be able to identify the service that provides the authoritative source for a set of data and marry that with other information, as necessary, whether it be sentiment analysis or what not, but you're always going to have to be able to point to that authoritative source.

Brown: Well, data architectures can be highly structured and big data can be somewhat unstructured. How do you marry the two?

Authoritative records

Gerty: How do you marry the two? Transactional systems are still very important. You have to be able to identify the authoritative records. Big data usually comes in multiple sources from multiple, different venues. The best example of the use of big data is around sentiment analysis, taking feeds from Twitter, Facebook, and these multiple sources, and then being able to analyze the information to the context of the authoritative sources. So your analytics have to take all of this into consideration.

Brown: Okay, we are just out of time. I just want to get a quick comment on these two other live streams. How are companies dealing with the shortage of big data scientists? Are they training current employees?

Gardner: A key question is who is actually spearheading this? Who is in the best position to be qualified? Under whose auspices do these big data initiatives fall? Let’s start with you Chris. Any insight as to how you've done it at NASA?

Gerty: I would draw a parallel from when I was in Mission Control and pretty highly trained. They wipe your brain and fill it up with everything you need to know, but we weren't really enabled to make those decisions, until we went through the data, page by page, and looked at each individual blip. If you can automate those, then you need less of whomever it is who's doing the job.

Automation there would have helped us immensely to make those decisions on the fly, rather than going over pages and pages of data from our batteries charging. It's not maybe that you need more data scientists, but you need the right data scientists. Then you need to be able to leverage off of other people’s data scientists. That's why open source is so attractive to us. You only need to do it once and then you can go off of it.

Gardner: Jim Hietala, the people that should be doing this, their qualification certification, organizational structure, any thoughts?

Hietala: It's way too early to certify people in this category right now. We really need individuals who went to graduate school to understand the proper application of analytics and mathematics. Those individuals would be highly valuable and prized, especially as they learn to how to apply that knowledge to your business.

Gardner: It’s tough to find the people who have deep and the wide expertise. Last word you, Bob?

Weisman: We have to take a look at career development within the CIO ranks. Making sense of data requires good business knowledge and too many people are being isolated within the CIO rank. They should be circulating throughout the companies, so they know what the company is doing, and then come back in. It's much more valuable.

There are some programs now that are joint ventures between the computer science departments and the business schools, and I think those are at the graduate level. As Andras was saying, they could provide people in their early 30s that can really do a fantastic job, and we really start taking advantage of this.

Brown: That's all we have time for. I think you've done a marvelous job, thank you very much.

Gardner: We’ve been talking with a panel of experts on how big data changes the status quo for architecting the enterprise. We've heard how large enterprises should better anticipate and prepare for the effects and impacts of big data, as well the simultaneous impacts of cloud computing and mobile.

This special BriefingsDirect discussion comes to you in conjunction with The Open Group Conference in Newport Beach, California. I'd like to thank our panel: Robert Weisman, CEO and Chief Enterprise Architect at Build The Vision; Andras Szakal, Vice President and CTO of IBM's Federal Division; Jim Hietala, Vice President for Security at The Open Group, and Chris Gerty, Deputy Program Manager at the Open Innovation Program at NASA.

This is Dana Gardner, Principal Analyst at Interarbor Solutions, your host and moderator through these thought leadership interviews. Thanks again for listening, and come back next time.
