Following OpenWorld, Oracle released version 4.0 of their Big Data Appliance Lite Virtual Machine for VirtualBox.
It includes OEL 6.4, RDBMS database 22.214.171.124 with Big Data SQL, Cloudera 5.1.2, NoSQL database 3.0.14 and GoldenGate 12c.
The “Getting Started” page now has all sorts of good documentation, white papers and hands-on labs you can try out.
Recently, Cloudera paid a visit to HQ and gave a presentation on their industry-standard implementation of Hadoop. I found it to be very insightful, especially given the paucity of details and proliferation of industry buzzwords that currently attaches itself to anything remotely related to “Big Data”.
I made some notes/observations during the presentation and did some follow-up reading afterwards. In case they’re useful, especially to those DBAs out there who might be expected to support Cloudera pretty soon, I typed up the notes and put them on here.
Over the last six weeks or so, I’ve been voraciously reading about Big Data, NoSQL, Hadoop and other emerging data management technologies which are clearly The Next Big Thing™ in IT. Personally, I find it fascinating to learn/think about how we will integrate different volumes and scales of data – both structured and unstructured, big and small – to give our organizations a clear, competitive edge in their industries.
As with all Next Big Things™, there are a lot of tremendous blogs and white papers written by some extremely smart and insightful people – and there are a lot of articles in “trade mags” which do nothing but fuel the runaway hype. Continue reading
I listened to an Oracle webinar on “The Value of Engineered Systems” yesterday. It didn’t really cover anything ground-breaking from my point of view, but it offered the following facts or thinking:
It should be noted that I’ve spent my career as a Oracle (relational) DBA of some description, so I’m sure there’s some degree of bias. However, I’m an advocate of Oracle databases because they’ve proven to be the best on the market.
My interest in Big Data was piqued recently when an excellent Oracle consultant was able to get me to understand its purpose and value during our ExCite review.
Here are a collection of links that I’ve found while reading up about the technology. I hope some are of interest.
“Big Data is like stomach bacteria” – I’ll admit that I included this one because I thought this one quote was awesome!
“Going forward, the companies that have the best data will win … until you can understand precisely what your customer wants, what they don’t want, how they want it and when they want it, you’ll be left to guess — and guessing is a very, very expensive business sport.”
“Too often, IT leaders look at the infrastructure needed for a Big Data analytics solution rather than the business requirement for the solution. They focus on the storage and compute capacity needed, or make decisions based on technology. This is usually driven by the need to contain ballooning infrastructure costs. Instead, IT leaders should focus on business outcomes of big data initiatives.”
Big Data requirements include a different … management of environments as compared to traditional deployments. This, in turn, requires changes in operational processes. Trying to add Big Data deployments into an existing environment will not help.
Big Data environments need to be structured separately and the operating processes to maintain them will also need to change. Failing to do so will only ensure a highly complex and non-sustainable architecture.”
