Integration of Amazon Redshift Cloud Data Warehouse (AWS SaaS DWH) with Talend Data Integration (DI) / Big Data (BD) / Enterprise Service Bus (ESB)

Posted in Cloud, EAI, ESB on June 26th, 2013 by Kai Wähner

In this blog post, I will show you how to „ETL“ all kinds of data to Amazon’s cloud data warehouse Redshift wit Talend’s big data components. Let’s begin with a short introduction to Amazon Redshift (copied from website):

„Amazon Redshift is [part of Amazon Web Services (AWS) and] a fast and powerful, fully managed, petabyte-scale data warehouse service in the cloud. With a few clicks in the AWS Management Console, customers can launch a Redshift cluster, starting with a few hundred gigabytes and scaling to a petabyte or more, for under $1,000 per terabyte per year.
Traditional data warehouses require significant time and resource to administer, especially for large datasets. In addition, the financial cost associated with building, maintaining, and growing self-managed, on-premise data warehouses is very high. Amazon Redshift not only significantly lowers the cost of a data warehouse, but also makes it easy to analyze large amounts of data very quickly.“

My Talks at JavaOne 2012: “Lessons learned from JVM Languages (Java vs Groovy vs Scala vs Clojure vs JRuby vs Jython vs Kotlin)” and “Cloud Integration with Apache Camel”

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.

Book Review “Cloud Computing Architected – Solution Design Handbook” by John Rhoton and Risto Haukioja

Posted in Cloud on October 15th, 2011 by admin

“Cloud Computing Architected – Solution Design Handbook” by John Rhoton and Risto Haukioja was published by Recursive Press in May 2011.

This book is a great addition to other books about cloud computing.

Why? It does NOT give a high-level overview of cloud computing. It does NOT explain the business value. Finally, it does NOT contain tutorials for any specific cloud products.

So what is the content of the book? It covers architectural options for designing a cloud. The book explains many important decisions which have to be done when creating a cloud service or a cloud application.

Cloud Integration with Apache Camel and Amazon Web Services (AWS): S3, SQS and SNS

Posted in Cloud, EAI, ESB, Java / JEE on August 30th, 2011 by Kai Wähner

The integration framework Apache Camel already supports several important cloud services (see my overview article at http://www.kai-waehner.de/blog/2011/07/09/cloud-computing-heterogeneity-will-require-cloud-integration-apache-camel-is-already-prepared for more details). This article describes the combination of Apache Camel and the Amazon Web Services (AWS) interfaces of Simple Storage Service (S3), Simple Queue Service (SQS) and Simple Notification Service (SNS). Thus, The concept of Infrastructure as a Service (IaaS) is used to access messaging systems and data storage without any need for configuration.

Rapid Cloud Development with Spring Roo – Part 2: VMware Cloud Foundry

Posted in Application Server, Cloud, Java / JEE on August 12th, 2011 by Kai Wähner

Spring Roo is a tool to offer rapid application development on the Java platform. I already explained when to use it: http://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 Cloud Foundry support of Spring Roo. GAE was discussed in part 1 of this article series (http://www.kai-waehner.de/blog/2011/07/18/rapid-cloud-development-with-spring-roo-%E2%80%93-part-1-google-app-engine-gae).

Deployment of a Cloud Foundry Application to the Cloud

The reference guide of Spring Roo gives an introduction at http://www.springsource.org/roo/guide?w=base-cloud-foundry, which describes the combination of Spring Roo and Cloud Foundry. In a nutshell, there is not much to do to deploy your (CRUD-) application in the Cloud Foundry cloud.

Cloud Computing Heterogeneity will require Cloud Integration – Apache Camel is already prepared!

Posted in Application Server, Cloud, ESB, Java / JEE, SOA on July 9th, 2011 by Kai Wähner

Cloud Computing is the future – if you believe market forecasts from companies such as Gartner. I think so, too. But everybody should be aware that there won’t be one single cloud solution, but several clouds. These clouds will be hosted at different providers, use products and APIs from different vendors and use different concepts (IaaS, PaaS, SaaS). Thus, in the future you will have to integrate these clouds as you integrate applications today.

When to use Spring Roo?

Posted in Application Server, Cloud, Java / JEE, Web Framework on April 5th, 2011 by Kai Wähner

In this article, I will tell you about my experiences with Spring Roo. I will give recommendations when to use Spring Roo and when not to use it (yet).

What is Spring Roo?

“Spring Roo is a lightweight developer tool that makes it fast and easy to deliver instant results. Best of all, you code 100% in Java and get to reuse all your existing Java knowledge, skills and experience. You’ll like it – and have plenty of fun too!” (http://www.springsource.org/roo)
Many introductory articles exist already, just use Google if you do not know Spring Roo yet. In a nutshell: Spring Roo is a Java-based tool (using the SpringSource Tool Suite which is based on Eclipse). It uses AspectJ to simulate many features of Grails and other frameworks with dynamic languages to improve the developer experience.

First-hand Report about the Certification „SOA Certified Professional“ (SOACP) of soaschool.com

Posted in Cloud, IT Certifications, SOA on February 1st, 2011 by Kai Wähner

This article is a first-hand report about preparing for the SOACP certification and passing the exam. I decided to do this certification after I met Thomas Erl at the SOA Symposium 2010 in Berlin, Germany (see this older blog). I will tell you, why I like this certification and why (in my opinion) it makes a lot of sense. But I will also criticize some small details.

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!
