Book Review: “Getting Started with NoSQL” by Gaurav Vaish (Packt Publishing)
“Getting Started with NoSQL” is a new book by PACKT PUBLISHING. It gives an introduction to different NoSQL concepts and products. Besides, it explains the differences to SQL databases and when to use which one. With 150 pages, the book is not extensive, but sufficient. It is a good introduction to NoSQL databases for developers, architects and decision makers.
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).
Systems Integration in the NoSQL Era with Apache Camel and Talend (MongoDB, Neo4j, HBase, AWS S3, Hazelcast, CouchDB)
In February 2013, I was at ApacheCon NA 2013 in Portland, Oregon, USA. My session was named “Systems Integration in the NoSQL Era with Apache Camel”. I showed how to integrate several different NoSQL databases such as MongoDB (document), Neo4j (graph), HBase (column), AWS S3 (key-value), or Hazelcast (in-memory).
Rapid Cloud Development with Spring Roo – Part 1: Google App Engine (GAE)
Spring Roo is a tool to offer rapid application development on the Java platform. I already explained when to use it: https://www.kai-waehner.de/blog/2011/04/05/when-to-use-spring-roo. Spring Roo supports two solutions for Cloud Computing at the moment: Google App Engine (GAE) and VMware Cloud Foundry. Both provide the Platform as a Service (PaaS) concept. This article will discuss the GAE support of Spring Roo. Cloud Foundry will be analyzed in part 2 of this article series.
