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.

Machine Learning Applied to Microservices

Posted in Analytics, Big Data, Business Intelligence, Cloud, Docker, Hadoop, Microservices, Middleware 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 respectively machine learning.

Trends at JavaOne 2016: Microservices, Docker, Cloud-Native Middleware

Posted in Cloud, Cloud-Native, Docker, ESB, Java / JEE, Microservices, Middleware, SOA on September 23rd, 2016 by Kai Wähner

Like every year, I attended JavaOne (part of Oracle World) in San Francisco in late September 2016. This is still one of the biggest conferences around the world for technical experts like developers and architects.

I planned to write a blog posts about new trends from the program, exhibition and chats with other attendees. Though, I can make it short: Besides focus on Java platform updates (Java 9, Java EE 8, etc.), I saw three hot topics which are highly related to each other: Microservices, Docker and Cloud. It felt like 80% of non-Java talks were about these three topics. The other 20% were Internet of Things (IoT), DevOps and some other stuff. Middleware was also a hot topic. Not always directly, but I was in several talks focusing on integration, orchestration of microservices, (IoT) gateways.

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!

Microservices, Containers, Docker and a Cloud-Native Architecture in the Middleware World

Posted in API Management, BPM, Cloud, Cloud-Native, Docker, EAI, ESB, Java / JEE, Microservices, Middleware, SOA on April 22nd, 2016 by Kai Wähner

In April 2016, I had two talks at JPoint in Moscow, Russia. The first talk was an existing talk about “How to Apply Big Data Analytics and Machine Learning to Real Time Processing”. The second talk was a brand new one: “Microservices and Containers in the Middleware World”. This article discusses and shows the new slide deck about how middleware is related to Microservices, Containers, Docker and Cloud-Native Architectures.

Key takeaways of the talk:

  • A cloud-native architecture enables flexible and agile development
  • Modern middleware leverages containers, Microservices and a cloud-native architecture

Comparison: TIBCO ActiveMatrix BusinessWorks 6 / Container Edition vs. BW5

Posted in API Management, Cloud, Docker, ESB, Microservices, SOA on April 6th, 2016 by Kai Wähner

[This article was posted some time ago on the TIBCO Blog, already. I also added some information about BusinessWorks Container Edition (BW CE) where appropriate. Most of the characteristics defined below are true for both, BW6 and BW CE]

TIBCO ActiveMatrix BusinessWorks 6 (BW6) is a modern integration and service delivery platform ready for modern concepts such Mobile, Cloud, Internet of Things or Microservices. This article is no introduction to integration and service delivery platforms in general, but focuses on differentiators of BusinessWorks 6 compared to other integration solutions available on the market. If you want to see a general introduction to TIBCO ActiveMatrix BusinessWorks 6, explaining its basic concepts and capabilities such as:

Microservices = Death of the Enterprise Service Bus (ESB)? – Slide Deck and Video Recording

Posted in API Management, Cloud, EAI, ESB, Java / JEE, Microservices, SOA on June 29th, 2015 by Kai Wähner

[UPDATE June 2016: Please also read this updated article about Microservices, Containers and Cloud-Native Architecture for Middleware]

In 2015, the middleware world focuses on two buzzwords: Docker and Microservices. Software vendors still sell products such as an Enterprise Service Bus (ESB) or Complex Event Processing (CEP) engines. How is this related?

Docker is a fascinating technology to deploy and distribute modules (middleware, applications, services) quickly and easily. Most people agree that Docker will change the future of software development in the next years. I will do another blog post about how Docker is related to TIBCO and how you can deploy and distribute Microservices with Docker and TIBCO products such as TIBCO EMS and BusinessWorks 6 easily.

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.
