You are not Facebook or Google? Why you should still care about Big Data and Apache Hadoop Ecosystem (Pig, Hive, Hortonworks, Cloudera, MapR, Informatica, Talend)

In March 2013, I was at 33rd Degree – “A Conference for Java Masters”. I had two talks, including a new one: “You are not Facebook or Google? Why you should still care about Big Data”. It is a great talk to give an overview about big data, especially from a business perspective (paradigm shift, business value, challenges). However, I also talk about alternatives for big data from a technology perspective, mainly about the defacto standard Apache Hadoop, its ecosystem, distributions, and tooling (i.e. big data suites).

What is the TCO difference between IBM WebSphere and Open Source JBoss? – Just my two cents…

I have spotted a really great article about comparing prices of open source and proprietary products: “What is the TCO difference between WebSphere and JBoss?”. The interesting aspect is, that this article is written by an IBM-biased company (Prolifics). Usually, only open source vendors write such comparisons. I really like this article, seriously! It is good to see comparisons not only by open source vendors, but also by vendors such as IBM (in this case, Prolifics cannot be considered unbiased, it is an IBM consulting company – but that is fine). I just want to give my two cents to this article in the following…
