Enterprise Integration Patterns (EIP) Revisited in 2014

Posted in EAI, ESB, SOA on July 17th, 2014 by Kai Wähner

Today, I had a talk about “Enterprise Integration Patterns (EIP) Revisited in 2014″ at Java Forum Stuttgart 2014, a great conference for developers and architects with 1600 attendees.

Enterprise Integration Patterns

Data exchanges between companies increase a lot. Hence, the number of applications which must be integrated increases, too. The emergence of service-oriented architectures and cloud computing boost this even more. The realization of these integration scenarios is a complex and time-consuming task because different applications and services do not use the same concepts, interfaces, data formats and technologies.

JBoss OneDayTalk 2013: “NoSQL Integration with Apache Camel – MongoDB, CouchDB, Neo4j, Cassandra, HBase, Hazelcast, Riak, etc.”

Posted in EAI, ESB, Java / JEE on October 24th, 2013 by Kai Wähner

JBoss OneDayTalk is a great annual event around open source development. I have done a talk about “NoSQL Integration with Apache Camel”. This blog post shows you the updated slide deck of this talk.

Abstract

SQL cannot solve several problems emerging with big data. A distributed, fault-tolerant architecture is necessary. NoSQL comes to the rescue, but therefore it does not use SQL as its query language or give full ACID guarantees. Thus, in the future you will have to learn new concepts and integrate these NoSQL databases as you integrate SQL databasestoday. The open source integration framework Apache Camel is already prepared for this challenging task.

Yet another new Camel book: “Apache Camel Messaging Systems” (Danger of Confusion) – PACKT PUBLISHING

Posted in EAI on October 8th, 2013 by Kai Wähner

“Apache Camel Messaging System” is a new book (see http://www.packtpub.com/apache-camel-messaging-system/book) published on September, 25th, 2013 by PACKT PUBLISHING (ISBN: 9781782165347). Author is Evgeniy Sharapov. As it’s subtitle says, the book describes how to “tackle integration problems and learn practical ways to make data flow between your application and other systems using Apache Camel”.

Apache Camel is the best integration framework “on the market”. It has very good domain specific languages, many connectors, different companies behind it, and an awesome worldwide open source community. So, seeing a new book about Apache Camel is always good news!

Apache Camel and Talend ESB: Management and Monitoring of Integration Routes and SOAP / REST Web Services (JMX, OSGi, logstash, ElasticSearch, Kibana, hawtio)

Posted in ESB on July 15th, 2013 by Kai Wähner

A question every customer asks me: How can you manage and monitor integration routes implemented with Apache Camel (http://camel.apache.org/) and / or Talend ESB (http://en.talend.com/products/esb) (which is based on Apache Camel and also available as open source version). This blog post will show different alternatives to answer this question. The good news first: As Apache Camel and Talend ESB are based on open standards, you can use your own frameworks and tools if tooling of the product is not sufficient. So, I will not talk just about features of Apache Camel or Talend ESB, but also about additional options. Except for Talend Administration Center (user interface on top of Talend ESB’s service monitoring and clustering features), all tools are open source. Talend Administration Center is only available in Talend’s enterprise editions.

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

Posted in Application Server, BPM, Cloud, EAI, ESB, Java / JEE, SOA on December 19th, 2012 by Kai Wähner

Disclaimer: I work for an “open source company”. The following is my personal opinion!

Great Article: “What is the TCO difference between WebSphere and JBoss?”

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…

Enterprise-ready Tool Support for Apache Camel

Posted in EAI, ESB, Java / JEE on November 23rd, 2012 by Kai Wähner

Apache Camel is my favorite integration framework on the Java platform due to great DSLs, a huge community, and so many different components. Camel is used by many developers from different companies all over the world. However, most guys are not aware that some really cool and – more important – enterprise-ready tooling is available for Camel, too. Many people ask me about Camel tooling when I do talks at conferences. This is the reason for this short blog post about Camel tooling.

[FYI: I work for Talend (one of the vendors). Please also read the comments from my Red Hat friends at the bottom!]

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.
