Microservices = Death of the ESB? (2016, Meetup Dublin)

Posted in API Management, Big Data, Cloud, Docker, EAI, ESB, IT Conferences, Microservices, SOA on January 29th, 2016 by Kai Wähner

I was invited to speak at Microservices Meetup Dublin this week. I updated my slide deck “Microservices – Death of the ESB?” … The meetup was fully booked with a waiting list; around 120 attendees came to Gild‘s office. (see attached link).

If you have not seen the slide deck last year, you should definitely take a look at this updated version with more recent information. I also incorporated valuable information from discussions with attendees in 2015’s sessions about this topic.

Systems Integration in the NoSQL Era with Apache Camel and Talend (MongoDB, Neo4j, HBase, AWS S3, Hazelcast, CouchDB)

Posted in EAI, IT Conferences, Persistence on February 28th, 2013 by Kai Wähner

In February 2013, I was at ApacheCon NA 2013 in Portland, Oregon, USA. It was a small, but great conference. I met so many awesome Apache experts and learned a lot about several Apache projects.

Besides all of the Hadoop related projects, I was especially interested in Apache Syncope, an open source system for managing digital identities in enterprise environments, and Apache Streams, a new Incubator project that aims to develop a scalable server for the publication, aggregation, filtering and re-exposure of enterprise social activities.

Posted in Cloud, EAI, ESB, IT Conferences, Java / JEE on October 3rd, 2012 by Kai Wähner

These days, I am at JavaOne 2012 in San Francisco. That’s the largest and most important Java conference worldwide. In this blog post, I wanna share the slides of my two talks…

Lessons learned: Use of Modern JVM Languages besides Java

I explain my lessones learned while using other programming languages on the Java Platform besides Java, e.g. Groovy, Scala, Clojure, JRuby, Jypthon, Erjang, and others.

Systems Integration in the Cloud Era – API vs. Integration Framework vs. Enterprise Service Bus (ESB)

Posted in Cloud, EAI, ESB, IT Conferences, SOA on September 24th, 2012 by admin

Today, I was at the SOA CLOUD Service Technology Symposium 2012 in London (http://www.servicetechsymposium.com). Believing the organisors, it is „the World’s Largest Conference Dedicated to SOA, Cloud Computing & Service Technology“.

I was at this conference for the second time. Two year ago, the conference took place in Berlin. Unfortunately, the venue was awful this time. It was uncomfortable, no seats / tables available, and the rooms for the sessions were tough to find. Nevertheless, it was an awesome international conference with plenty of good content regarding SOA and Cloud Computing.

Progress Report from CamelOne 2012 in Boston (Apache Camel, ActiveMQ, ServiceMix, CXF)

Posted in IT Conferences, Uncategorized on May 17th, 2012 by Kai Wähner

This week, I was at CamelOne 2012 in Boston, organized by FuseSource.  The sessions addressed several open source integration projects from Apache. Here is a short summary of the event…


Sessions covered several open source projects such as Apache Camel, Apache ActiveMQ, Apache ServiceMix, and Apache CXF. Attendees learned directly from their peers and other industry experts how open source can deliver measurable technical and business benefits to their organizations.

Besides Camel, ActiveMQ, ServiceMix and CXF, several other interesting topics were covered, for example:

This week, I was at Confess 2012 in Leogang, Salzburg (Austria). Confess is an international conference for Java professionals in its fifth year, organized by IRIAN and the EJUG Austria. It is reasonably priced with 275 € for the two-day conference, and 500 € for the workshop day. The speaker lineup is very good with many well-known international speakers, such as JSF spec lead Edwuard Burns from Oracle America, Hazem Saleh from IBM Egypt, or Jürgen Höller from SpringSource.


There were six main topics for this year’s conference:

  • Concurrent Programming
  • Mobile Development
  • Cloud Computing

Oracle complains about Sun’s Java-Release-Cycles – OpenJDK will become more important

Posted in IT Conferences, Java / JEE on April 12th, 2011 by Kai Wähner

Oracle complains about Sun’s Java-Release-Cycles

A keynote of Dalibor Topic (Oracle) criticizes the Java-Release-Cycles of Sun Microsystems at the Java conference „CONFESS 2011“ in Vienna, Austria. After showing the past of Java SE from version 1 to 6, he showed a SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) named „SWOT – Sun days“ (Picture from my Tweet). One weakness stated the slow release cycle of Java SE. Oracle will do a better job in the future, beginning with Java 7 in 2011 and Java 8 in 2012. Further releases (Java 9 and so on) also seem to be in planning stage already. Java shall remain the most used language!

Book Review “Apache Camel In Action”

Posted in EAI, ESB, IT Conferences, Java / JEE on January 24th, 2011 by Kai Wähner

Smart Enterprise Application Integration with Apache Camel

In January, I spent a lot of time playing with Apache Camel. I really like this EAI-framework. Thus, I will hold a workshop in our company and at some external events, e.g. at the IT conference “Confess 2011” in Vienna.  It helps you a lot in any integration project within the Java environment. The book “Camel in Action” released some weeks ago. If you want to learn Apache Camel, you need this book! Here is my short review.

Bad Idea: A Keynote at SOA / Cloud Symposium 2010 in Berlin as Skype Call

Posted in Cloud, IT Conferences, SOA on October 6th, 2010 by Kai Wähner

Bad Idea: A Keynote at SOA / Cloud Symposium 2010 in Berlin as Skype Call ?!

In October 2010, I was at the IT conference „SOA / Cloud Symposium 2010“. I really liked the conference as I stated in another blog entry (http://www.kai-waehner.de/blog/2010/10/06/soa-cloud-symposium-2010-in-berlin/). But one concern really upset me…

What is a good keynote?

I really enjoyed the very good keynote of Christian Klezl (Vice President and Cloud Leader  of IBM Northeast Europe). This keynote contained everything I expect from a keynote: Good slides, good body language, interesting information, and a structured presentation which never becomes boring. Good job!
