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: Data Preparation vs. Inline Data Wrangling in Machine Learning and Deep Learning Projects

Posted in Analytics, Big Data, Business Intelligence, Hadoop on February 13th, 2017 by Kai Wähner

I want to highlight a new presentation about Data Preparation in Data Science projects:

“Comparison of Programming Languages, Frameworks and Tools for Data Preprocessing and (Inline) Data Wrangling  in Machine Learning / Deep Learning Projects”

Data Preparation as Key for Success in Data Science Projects

A key task to create appropriate analytic models in machine learning or deep learning is the integration and preparation of data sets from various sources like files, databases, big data storages, sensors or social networks. This step can take up to 80% of the whole project.

Hybrid Integration Architecture is the New Default

Posted in API Management, Cloud, Cloud-Native, Docker, EAI, ESB, Microservices, Middleware, SOA on August 5th, 2016 by Kai Wähner

The IT world is moving forward fast. 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 though different departments and lines of business. Several different concepts, technologies and deployment options are used. A single integration backbone is not sufficient anymore in this era of integration. Therefore, a Hybrid Integration Architecture is getting the new default in most enterprises.

Different user roles need to leverage different tools to integrate applications, services and APIs for their specific need. A key for success is that all integration and business services work together across different platforms in a hybrid world with on premise and cloud deployments.

Voxxed Article: Microservices, Containers and Cloud-Native Architectures for Middleware

Posted in Cloud, Cloud-Native, Docker, ESB, Microservices on June 2nd, 2016 by Kai Wähner

I wanna refer to a new article published today at Voxxed: “Microservices, Containers and Cloud-Native Architectures for Middleware“. Here is the summary:

Summary of the Article

The IT world is moving forward fast. I wrote about Microservices and whether that spells the death of the Enterprise Service Bus and other middleware a year ago. This article is a “follow-up” and update to discuss how relevant microservices, containers and a cloud-native architecture is for middleware. It is unbelievable how fast enterprises of all sizes are moving forward with these topics!

Micro Services Architecture = Death of Enterprise Service Bus (ESB)?

Posted in API Management, Cloud, EAI, ESB, In Memory, Java / JEE on January 8th, 2015 by Kai Wähner

These days, it seems like everybody is talking about microservices. You can read a lot about it in hundreds of articles and blog posts, but my recommended starting point would be this article by Martin Fowler, which initiated the huge discussion about this new architectural concept. This article is about the challenges, requirements and best practices for creating a good microservices architecture, and what role an Enterprise Service Bus (ESB) plays in this game.

Branding and Marketing: EAI vs. SOA vs. ESB vs. Microservices

Let’s begin with a little bit of history about Service-oriented Architecture (SOA) and Enterprise Service Bus to find out why microservices have become so trendy.

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.

Slides online: “Enterprise Integration Patterns Revisited” – Talk at OBJEKTspektrum Information Days 2013

Posted in EAI, ESB on November 19th, 2013 by Kai Wähner

I had a brand new talk at OBJEKTspektrum Information Days 2013 in Frankfurt and Munich this week: Enterprise Integration Patterns Revisited. I wanna share my slides with you.

Content

Applications have to be integrated – no matter which programming languages, databases or infrastructures are used. However, the realization of integration scenarios is a complex and time-consuming task. Over 10 years ago, Enteprise Integration Patterns (EIP) became the world wide defacto standard for splitting huge, complex integration scenarios into smaller recurring problems. These patterns appear in almost every integration project.
This session revisits EIPs and gives shows status quo. After giving a short introduction with several examples, the audience will learn which EIPs still have a „right to exist“, and which new EIPs emerged in the meantime. The end of the session shows different frameworks and tools which already implement EIPs and therefore help the architect to reduce efforts a lot.

WJAX 2013 Slides online: Big Data beyond Apache Hadoop – How to integrate ALL your Data with Camel and Talend

Posted in Uncategorized on November 5th, 2013 by Kai Wähner

I just want to publish my updated slide deck from WJAX 2013 in Munich. I have integrated some real world use cases for showing Hadoop integration with Apache Camel and Talend Open Studio for Big Data.

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.

How to choose the right Open Source Integration Framework – Apache Camel (JBoss, Talend), Spring Integration (Pivotal) or Mule ESB? – JavaOne 2013

Posted in EAI, ESB on September 25th, 2013 by Kai Wähner

Slides from my talk “How to choose the right Integration Framework” at JavaOne 2013, San Francisco, are online.

Abstract

Data exchanges between companies increase a lot. The number of applications which must be integrated increases, too. The interfaces use different technologies, protocols and data formats. Nevertheless, the integration of these applications shall be modeled in a standardized way, realized efficiently and supported by automatic tests.

Three integration frameworks are available in the JVM environment, which fulfil these requirements: Apache Camel, Spring Integration and Mule. They implement the well-known Enteprise Integration Patterns (EIP) and therefore offers a standardized, domain-specific language to integrate applications.
