Can and should Apache Kafka replace a database? How long can and should I store data in Kafka?…
Use Cases and Success Stories for In-Memory Data Grids, e.g. TIBCO ActiveSpaces, Oracle Coherence, Infinispan, IBM WebSphere eXtreme Scale, Hazelcast, Gigaspaces, GridGain, Pivotal Gemfire (Presentation by Kai Wähner at NoSQL Matters 2014 in Barcelona) – NOT SAP HANA 🙂
Slides from my talk at NoSQL Roadshow 2013 in Zurich are online. NoSQL Roadshow is a great event series by Trifork, which offers a lot of NoSQL sessions and events all over the world.
Just a short blog post with a link to an interview which I gave for NoSQL Roadshow 2013…
Just a short reference to a video of my talk “Big Data beyond Hadoop – How to integrate…
“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.
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).
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).
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.
The Cloud-Camp was a free „Unconference“, which took place one day before the SOA / Cloud Symposium 2010 in Berlin, Germany. You can find more information about Cloud Camps at http://www.cloudcamp.org.
