As a technologist and evangelist working in the big data marketplace it is certainly exciting. I am excited by the new products we are bringing to market and how this new functionality really helps to bridge the gap for Enterprises adoption. It is also surreal, in terms of the number of blog posts, tweets on Big Data and there seems to be a new big data conference cropping up on a weekly basis across Europe :-)
It is interesting to monitor other vendors in the marketplace and how they position their offerings. There is certainly a lot of clever marketing going on (that I believe in time will show a lack of substance) and some innovation too, . You know who you are.... But jump aboard the bandwagon. Just because you might have Hadoop and your database + Analytics within the same rack that doesn't mean they are integrated.
It is also interesting the fervor that people bring when discussing open source products. Those people who know me, know that I am a long time UNIX guru over 20 years from the early BSD distributions to working with UNIX on mainframes, to even getting minix to work on PC's before Linux came along. Fun times, but I was young free and single and enjoyed the technical challenge. I was also working in a research department in a university. However the argument that Hadoop is free and easy to implement and will one day replace data warehousing, doesn't ring true for me. Certainly it is true is has a place, and does provide value, but it doesn't come at no cost. Certainly Hortonworks and Cloudera provide distributions that are reducing the installation/configuration and management effort, but you have multiple distributions, starting to go in different directions? MapR for example?
How many enterprises really want to get that involved in running and maintaining this infrastructure. Surely they should be focused on identify new insights that provides business benefits or gives greater competitive advantage. IT has an important role to play, but it will be the business users ultimately that need to leverage the platform to gain these insights.
It is no use getting insights, if you don't take action on them either.
Insight gained from big data analytics should be fed into existing EDW (if they exist) so they can enhance what you already have and the EDW provides you with a better means of operationalizing the results.
I say to those people who think Hive is a replacement for SQL, not yet it ain't, it doesn't provide the completeness or performance that a pure SQL engine can provide. You don't replace 30+ years of R&D that quickly...
To the NoSQL folks, this debate is taking on religious fervour at times, It has a role, but I don't see it replacing the relational database overnight either.
In a previous role I managed a complex DB Environment that included a Big Data platform for a company that operated in the online gaming marketplace in a very much 24 X 7 environment, with limited downtime. It was the bleeding edge at times, growing very fast. If we had Teradata Aster 5.0 then, my life would have been so much easier. Se had an earlier release but we learned a lot. We proved the value of SQL combined with the Map Reduce programming paradigm. We saw the ease of scaling and reliability, We delivered important insights into various types of fraud, and took action on them, which yielded positive kudos for the company and increased player trust, which is very important in an online marketplace. We also were able to leverage the platform for an novel ODS requirement and had both executing simultaneously along with various ad-hoc queries. I was also lucky then and since to meet real visionaries, like Mayank and Tasso which gives you confidence in the approach and the future direction
When you think of big data analytics, it just not just about multi structure data or new data sources. Using SQL/MR for example may be the most performant way to yield new insights from existing relational data. Also consider what 'grey data' already exists within your organisations, it maybe easier to tap into that first, before sourcing new data feeds. The potential business value should drive that decision though.
Do not under estimate the important of having a discovery platform as you tackle these new Big Data Challenges. Yes, you will probably need new people or even better, train existing analysts to take on these new skills and grow your own data scientists. The ease of this approach, will be in how feature rich your discovery platform is, How many built in and useful analytical functions are provided to get you started, before you may have to develop specific ones of your own.
I suppose, some would say I am rambling with these comments and not expressing them very elegantly, but help is at hand :-). We recently put together a short webinar, I think it is about 20 minutes duration.
The Big Data Analytics Landscape: Trends, Innovations and New Business Value, featuring Gartner Research Vice President Merv Adrian and Teradata Aster Co-President Tasso Argyros. In the video, Merv and Tasso, answer these questions and more, including how organizations can find the right solution - to make smarter decisions, take calculated risks, and gain deeper insights than their industry peers.
I suggest if you have the time to spare... watch the video
What do you think?
For me it is all about the analytics and the new insights that can be gained and acted upon
