Big Data Blame

I thought I’d share a very interesting article on Big Data and its massively underwhelming (so far) business impact.

Might the trade mag hype machine be close to admitting that Big Data is a far more complicated beast than they have been suggesting? Surely not…

Hadoop Rolls Out Transparent Encryption

This could be a big deal for Hadoop and enterprise adoption. End-to-end encryption should be a big winner, especially with support groups, as it’s largely been pushed to the sidebar until now.

Microsoft’s Analytics Platform System Appliance

In the last couple of months, Microsoft have repackaged their Parallel Data Warehouse appliance and now offer their new Analytics Platform System (APS) instead.

APS is a turnkey/black box appliance which offers the PDW, a Hadoop cluster (HDInsight, an implementation of Hortonworks) and an integration feature like Oracle’s Big Data SQL – called PolyBase – to allow the PDW to use the Hadoop data. Continue reading

Cloudera Primer for Relational DBAs

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.

Oracle’s “Nightmare”?

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

Public Cloud vs. Private Cloud vs. Engineered Systems?

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.

  • There will be an estimated 50 billion Internet devices by 2020.
  • 90% of all data in the world has been created within the last 2 years.
  • An estimated 50x data growth is expected by 2020 thanks to the Internet of Things, Social Media, surveillance
  • An estimated 340 trillion IP addresses will be required by 2020 – I hope SOMEONE is using IPv6 by then!
  • IT departments need to grow by 4% per annum just to maintain existing systems, excluding any growth of business needs – yet companies continue to make cuts in infrastructure and avoid investing in R&D.
  • Storage accounts for 17% of IT budget.
  • Oracle do NOT expect customers to host their PRODUCTION systems in the PUBLIC Cloud – they see customers to host PRODUCTION in a PRIVATE Cloud (either hosted by the customer or via co-lo) ***
  • Instead, they expect SaaS for Development to be the big draw for the PUBLIC Cloud.
  • Engineered systems simplifies IT.
  • Oracle is awesome.
  • Exadata is awesome on steroids.
