Presentaties februari 2015

Voor februari 2015 staan er diverse presentaties op de planning met name op het gebied van architectuur en agile:

Kennissesies agile architectuur bij Ordina

Op 5 februari organiseert Ordina een kennissessie over agile architectuur in de praktijk. Net als op het LAC zal ik een presentatie houden over de waarde van architectuur en time-to-market. Waarin ik laat zien dat juist architectuur waarde en snelheid kan bieden bij de time-to-market. Dit aan de (more...)

Big Data and the importance of Meta-Data

Data isn't really respected in businesses, you can see that because unlike other corporate assets there is rarely a decent corporate catalog that shows what exists and who has it.  In the vast majority of companies there is more effort and automation put into tracking laptops than there is into cataloging and curating information. Historically we've sort of been able to get away with this

Security Big Data – Part 7 – a summary

Over six parts I've gone through a bit of a journey on what Big Data Security is all about. Securing Big Data is about layers Use the power of Big Data to secure Big Data How maths and machine learning helps Why its how you alert that matters Why Information Security is part of Information Governance Classifying Risk and the importance of Meta-Data The fundamental point here is that

Securing Big Data Part 6 – Classifying risk

So now your Information Governance groups consider Information Security to be important you have to then think about how they should be classifying the risk.  Now there are docs out there on some of these which talk about frameworks.  British Columbia's government has one for instance that talks about High, Medium and Low risk, but for me that really misses the point and over simplifies the

Securing Big Data Part 5 – your Big Data Security team

What does your security team look like today? Or the IT equivalent, "the folks that say no".  The point is that in most companies information security isn't actually something that is considered important.  How do I know this?  Well because basically most IT Security teams are the equivalent of the nightclub bouncers, they aren't the people who own the club, they aren't as important as the

Using Oracle Big Data SQL to Add Dimensions and Attributes to Hadoop Reporting

In a previous post I looked at using Oracle’s new Big Data SQL product with ODI12c, where I used Big Data SQL to expose two Hive tables as Oracle external tables, and then join them using the BETWEEN operator, something that’s not possible with regular HiveQL. In this post I’m going to look at using Oracle Big Data SQL with OBIEE11g, to enable reporting against Hive tables without the need to use Hive ODBC (more...)

Securing Big Data – Part 4 – Not crying Wolf.

In the first three parts of this I talked about how Securing Big Data is about layers, and then about how you need to use the power of Big Data to secure Big Data, then how maths and machine learning helps to identify what is reasonable and was is anomalous. The Target Credit Card hack highlights this problem.  Alerts were made, lights did flash.  The problem was that so many lights flashed and

Securing Big Data – Part 3 – Security through Maths

In the first two parts of this I talked about how Securing Big Data is about layers, and then about how you need to use the power of Big Data to secure Big Data.  The next part is "what do you do with all that data?".   This is where Machine Learning and Mathematics comes in, in other words its about how you use Big Data analytics to secure Big Data. What you want (more...)

Are you ready to learn something new in 2015?

We all know the saying: When the student is ready, the teacher will appear My advice is to empty your cup, daily, so that when the teacher appears you will recognize them. Unless we are humble in our hearts and in our spirit, we are not open to new things and to learning. The teacher […]

Securing Big Data – Part 2 – understanding the data required to secure it

In the first part of Securing Big Data I talked about the two different types of security.  The traditional IT and ACL security that needs to be done to match traditional solutions with an RDBMS but that is pretty much where those systems stop in terms of security which means they don't address the real threats out there, which are to do with cyber attacks and social engineering.  An ACL is only

Securing Big Data – Part 1

As Big Data and its technologies such as Hadoop head deeper into the enterprise so questions around compliance and security rear their heads. The first interesting point in this is that it shows the approach to security that many of the Silicon Valley companies that use Hadoop at scale have taken, namely pretty little really.  It isn't that protecting information has been seen as a massively

Top 10 Rittman Mead Blog Posts from 2014

It’s the afternoon of New Year’s Eve over in the UK, so to round the year off here’s the top 10 blog posts from 2014 from the Rittman Mead blog, based on Google Analytics stats (page views for 2014 in brackets, only includes articles posted in 2014)

Watch: Riak vs. Oracle

Every data platform has its value, and deciding which one will work best for your big data objectives can be tricky—Alex Gorbachev, Oracle ACE Director, Cloudera Champion of Big Data, and Chief Technology Officer at Pythian, has recorded a series of videos comparing the various big data platforms and presents use cases to help you identify which ones will best suit your needs.

Riak and Oracle are completely different platforms. Alex explains that “Oracle database (more...)

Connecting OBIEE11g on Windows to a Kerberos-Secured CDH5 Hadoop Cluster using Cloudera HiveServer2 ODBC Drivers

In a few previous posts and magazine articles I’ve covered connecting OBIEE11g to a Hadoop cluster, using OBIEE 11.1.1.7 and Cloudera CDH4 and CDH5 as the examples. Things get a bit complicated in that the DataDirect Apache Hive ODBC drivers that Oracle ship are only for HiveServer1 and not the HiveServer2 version that CDH4 and CDH5 use, and the Linux version of OBIEE 11.1.1.7 won’t work with the (more...)

What makes MapR superior to other Hadoop distributions?

These days Hortonworks with their IPO and Cloudera sitting on $1bn of cash grab all the headlines. However,the real visionary in the field is someone else. Someone blasting the previous world record in TeraSort . A Hadoop distribution on both Amazon Web Services and the Google Compute Engine. A company that Google is invested in. While their competitors have been in skirmishes with each other, MapR has been quietly working away and innovating.

Trends in Big Data, Hadoop, Business Intelligence, Analytics and Dashboards

How has the interest in Big Data, Hadoop, Business Intelligence, Analytics and Dashboards changed over the years?

One easy way to gauge the interest is to measure how much news is generated for the related term and Google Trends allows you do that very easily.

After plugging all of the above terms in Google trends and further analysis leads to the following visualizations.

Big Data… Is Hadoop the good way to start?

In the past 2 years, I have met many developers, architects that are working on “big data” projects. This sounds amazing, but quite often the truth is not that amazing. TL;TR You believe that you have a big data project? Do not start with the installation of an Hadoop Cluster -- the "how" Start to talk to business people to understand their problem -- the "why" Understand the data you must

Data Warehouse Appliance Offerings

Introduction

Information Technology units will continue to be challenged by the unbridled growth of their organization’s data stores. An ever-increasing amount of data needs to be extracted, cleansed, analyzed and presented to the end user community. Data volumes that were unheard of a year ago are now commonplace. Day-to-day operational systems are now storing such large amounts of data that they rival data warehouses in disk storage and administrative complexity. New trends, products, and strategies, (more...)

Top 100 analytics companies ranked and scored by Mattermark

Let us move on from Grass Eating Sauropods and talk about who’s who in the analytic space.

For every dime there are dozen analytic companies. Everybody who provides a freaking dashboard is an analytic company. Anybody that merely mentions Google, Facebook, Hadoop etc in the same sentence is somehow into BigData. Haven’t you stumbled across company pages where they claim to be expert in analytics and big data but they want you to schedule a (more...)

Say “Big Data” One More Time (I dare you!)
