Identical to that, earlier than going large knowledge, every determination maker has to know what they’re coping with. Right here, our large knowledge consultants cowl 7 main large knowledge challenges and supply their options. Utilizing this ‘insider data’, it is possible for you to to tame the scary large knowledge creatures with out letting them defeat you within the battle for constructing a data-driven enterprise.

Problem #1: Inadequate understanding and acceptance of large knowledge

Oftentimes, firms fail to know even the fundamentals: what large knowledge truly is, what its advantages are, what infrastructure is required, and so on. And not using a clear understanding, a giant knowledge adoption undertaking dangers to be doomed to failure. Corporations might waste a number of time and assets on issues they don’t even know how you can use.

And if staff don’t perceive large knowledge’s worth and/or don’t need to change the present processes for the sake of its adoption, they’ll resist it and impede the corporate’s progress.


Huge knowledge, being an enormous change for an organization, must be accepted by prime administration first after which down the ladder. To make sure large knowledge understanding and acceptance in any respect ranges, IT departments want to arrange quite a few trainings and workshops.

To see to large knowledge acceptance much more, the implementation and use of the brand new large knowledge resolution must be monitored and managed. Nevertheless, prime administration shouldn’t overdo with management as a result of it might have an antagonistic impact.

Problem #2: Complicated number of large knowledge applied sciences

Variety of big data technologies

It may be straightforward to get misplaced within the number of large knowledge applied sciences now accessible available on the market. Do you want Spark or would the speeds of Hadoop MapReduce be sufficient? Is it higher to retailer knowledge in Cassandra or HBase? Discovering the solutions may be tough. And it’s even simpler to decide on poorly, in case you are exploring the ocean of technological alternatives and not using a clear view of what you want.


If you’re new to the world of massive knowledge, making an attempt to hunt skilled assist can be the appropriate solution to go. You may rent an knowledgeable or flip to a vendor for giant knowledge consulting. In each circumstances, with joint efforts, you’ll have the ability to work out a method and, based mostly on that, select the wanted expertise stack.

Problem #3: Paying a great deal of cash

Big data on-premises vs. in-cloud costs

Huge knowledge adoption initiatives entail a number of bills. In case you go for an on-premises resolution, you’ll must thoughts the prices of latest {hardware}, new hires (directors and builders), electrical energy and so forth. Plus: though the wanted frameworks are open-source, you’ll nonetheless have to pay for the event, setup, configuration and upkeep of latest software program.

In case you determine on a cloud-based large knowledge resolution, you’ll nonetheless have to rent workers (as above) and pay for cloud companies, large knowledge resolution growth in addition to setup and upkeep of wanted frameworks.

Furthermore, in each circumstances, you’ll want to permit for future expansions to keep away from large knowledge progress getting out of hand and costing you a fortune.


The actual salvation of your organization’s pockets will rely in your firm’s particular technological wants and enterprise objectives. As an example, firms who need flexibility profit from cloud. Whereas firms with extraordinarily harsh safety necessities go on-premises.

There are additionally hybrid options when components of knowledge are saved and processed in cloud and components – on-premises, which can be cost-effective. And resorting to knowledge lakes or algorithm optimizations (if finished correctly) also can get monetary savings:

  1. Knowledge lakes can present low-cost storage alternatives for the info you don’t want to research for the time being.
  2. Optimized algorithms, of their flip, can cut back computing energy consumption by 5 to 100 instances. Or much more.

All in all, the important thing to fixing this problem is correctly analyzing your wants and selecting a corresponding plan of action.

Problem #4: Complexity of managing knowledge high quality

Knowledge from various sources

Ultimately, you’ll run into the issue of knowledge integration, for the reason that knowledge you might want to analyze comes from various sources in a wide range of totally different codecs. As an example, ecommerce firms want to research knowledge from web site logs, call-centers, rivals’ web site ‘scans’ and social media. Knowledge codecs will clearly differ, and matching them may be problematic. For instance, your resolution has to know that skis named SALOMON QST 92 17/18, Salomon QST 92 2017-18 and Salomon QST 92 Skis 2018 are the identical factor, whereas firms ScienceSoft and Sciencesoft should not.

Unreliable knowledge

No person is hiding the truth that large knowledge isn’t 100% correct. And all in all, it’s not that important. But it surely doesn’t imply that you simply shouldn’t in any respect management how dependable your knowledge is. Not solely can it comprise flawed info, but in addition duplicate itself, in addition to comprise contradictions. And it’s unlikely that knowledge of extraordinarily inferior high quality can deliver any helpful insights or shiny alternatives to your precision-demanding enterprise duties.


Big data quality

There’s a entire bunch of methods devoted to cleaning knowledge. However first issues first. Your large knowledge must have a correct mannequin. Solely after creating that, you’ll be able to go forward and do different issues, like:

  • Examine knowledge to the only level of fact (for example, examine variants of addresses to their spellings within the postal system database).
  • Match information and merge them, in the event that they relate to the identical entity.

However thoughts that large knowledge isn’t 100% correct. You must understand it and take care of it, which is one thing this text on large knowledge high quality can assist you with.

Problem #5: Harmful large knowledge safety holes

Safety challenges of massive knowledge are fairly an unlimited difficulty that deserves an entire different article devoted to the subject. However let’s have a look at the issue on a bigger scale.

Very often, large knowledge adoption initiatives put safety off until later levels. And, frankly talking, this isn’t an excessive amount of of a sensible transfer. Huge knowledge applied sciences do evolve, however their security measures are nonetheless uncared for, because it’s hoped that safety shall be granted on the applying degree. And what can we get? Each instances (with expertise development and undertaking implementation) large knowledge safety simply will get solid apart.


The precaution towards your attainable large knowledge safety challenges is placing safety first. It’s notably necessary on the stage of designing your resolution’s structure. As a result of if you happen to don’t get together with large knowledge safety from the very begin, it’ll chunk you once you least anticipate it.

Problem #6: Difficult means of changing large knowledge into priceless insights

Valuable insights with big data

Right here’s an instance: your super-cool large knowledge analytics appears to be like at what merchandise pairs folks purchase (say, a needle and thread) solely based mostly in your historic knowledge about buyer habits. In the meantime, on Instagram, a sure soccer participant posts his new look, and the 2 attribute issues he’s sporting are white Nike sneakers and a beige cap. He appears to be like good in them, and individuals who see that need to look this manner too. Thus, they rush to purchase the same pair of sneakers and the same cap. However in your retailer, you’ve gotten solely the sneakers. Because of this, you lose income and perhaps some loyal clients.


The explanation that you simply did not have the wanted gadgets in inventory is that your large knowledge instrument doesn’t analyze knowledge from social networks or competitor’s net shops. Whereas your rival’s large knowledge amongst different issues does be aware tendencies in social media in near-real time. And their store has each gadgets and even provides a 15% low cost if you happen to purchase each.

The concept right here is that you might want to create a correct system of things and knowledge sources, whose evaluation will deliver the wanted insights, and make sure that nothing falls out of scope. Such a system ought to typically embrace exterior sources, even when it might be troublesome to acquire and analyze exterior knowledge.

Problem #7: Troubles of upscaling

The most common function of massive knowledge is its dramatic capacity to develop. And one of the critical challenges of massive knowledge is related precisely with this.

Your resolution’s design could also be thought by and adjusted to upscaling with no further efforts. However the actual drawback isn’t the precise means of introducing new processing and storing capacities. It lies within the complexity of scaling up so, that your system’s efficiency doesn’t decline, and also you keep inside funds.


The initially precaution for challenges like it is a first rate structure of your large knowledge resolution. So long as your large knowledge resolution can boast such a factor, much less issues are more likely to happen later. One other extremely necessary factor to do is designing your large knowledge algorithms whereas conserving future upscaling in thoughts.

However moreover that, you additionally have to plan in your system’s upkeep and help in order that any adjustments associated to knowledge progress are correctly attended to. And on prime of that, holding systematic efficiency audits can assist determine weak spots and well timed deal with them.

Win or lose?

As you may have observed, a lot of the reviewed challenges may be foreseen and handled, in case your large knowledge resolution has an honest, well-organized and thought-through structure. And because of this firms ought to undertake a scientific method to it. However moreover that, firms ought to:

  • Maintain workshops for workers to make sure large knowledge adoption.
  • Rigorously choose expertise stack.
  • Thoughts prices and plan for future upscaling.
  • Do not forget that knowledge isn’t 100% correct however nonetheless handle its high quality.
  • Dig deep and broad for actionable insights.
  • By no means neglect large knowledge safety.

If your organization follows the following pointers, it has a good likelihood to defeat the Scary Seven.
