Case Study: From a Monolith to Cloud, Containers, Microservices

Posted in API Management, Cloud, Cloud-Native, Docker, EAI, ESB, Java / JEE, Microservices, Middleware, SOA on February 24th, 2017 by Kai Wähner

The following shows a case study about successfully moving from a very complex monolith system to a cloud-native architecture. The architecture leverages containers and Microservices. This solve issues such as high efforts for extending the system, and a very slow deployment process. The old system included a few huge Java applications and a complex integration middleware deployment.

The new architecture allows flexible development, deployment and operations of business and integration services. Besides, it is vendor-agnostic so that you can leverage on-premise hardware, different public cloud infrastructures, and cloud-native PaaS platforms.

Comparison Of Log Analytics for Distributed Microservices – Open Source Frameworks, SaaS and Enterprise Products

Posted in Analytics, Big Data, Business Intelligence, Cloud, Hadoop, Microservices, SOA on October 20th, 2016 by Kai Wähner

I had two sessions at O’Reilly Software Architecture Conference in London in October 2016. It is the first #OReillySACon in London. A very good organized conference with plenty of great speakers and sessions. I can really recommend this conference and its siblings in other cities such as San Francisco or New York if you want to learn about good software architectures and new concepts, best practices and technologies. Some of the hot topics this year besides microservices are DevOps, serverless architectures and big data analytics.

I want to share the slide of my session about comparing open source frameworks, SaaS and Enterprise products regarding log analytics for distributed microservices:

TIBCO’s Hybrid Integration Platform

Posted in API Management, Cloud, Cloud-Native, Docker, EAI, ESB, Microservices, SOA on September 14th, 2016 by Kai Wähner

[Originally posted on the TIBCO Blog]

The IT world is moving forward rapidly. The digital transformation changes complete industries and peels away existing business models. Cloud services, mobile devices, and the Internet of Things establish wild spaghetti architectures through different departments and lines of business. Several different concepts, technologies, and deployment options are used. A single integration backbone is not sufficient in this era anymore.

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.
