Thanks to my company – Scott Logic – I recently had a pleasure of attending the Devoxx UK 2018 conference. Among many interesting talks and speakers, there were quite a few Spring celebrities present. Juergen Holler (Father of Spring), Josh Long and Mark Heckler were all there. Here are my impressions from the conference. Continue reading “The State of Spring in 2018 – Devoxx UK Impressions”
Spring Cloud Data Flow requires quite a few dependencies in order to run it. In this blog post, I will show you Docker Compose tool and how it can be used to make that setup easy. Continue reading “Quick setup for Spring Cloud Data Flow with Docker Compose”
I have recently spoken at a meetup about Practical Choreography with Spring Cloud Stream. It was a great event where I was asked many questions after the talk. One question got me thinking: “What book about Spring Cloud do you recommend?” which as it turns out boils down to “How do you learn Spring Cloud?”. I heard that question posed a few times before in different ways. Here, I will give you my answer on what I think is the best way of learning Spring Cloud.

I have recently spent quite a lot of time playing with Spring Cloud Data Flow (SCDF). It is an amazing platform that can be used for many things. Talking about it with some of my colleagues I realized that not everyone knows what are the common use cases. Thinking about it further I realized that I don’t know the full scope of capabilities and business problems that it can solve! In this article I look at different uses for Spring Cloud Data Flow based on what the platform offers and actual stories from companies using it in production. The examples come from Spring One Platform 2017 conference. Continue reading “Spring Cloud Data Flow – Use Cases”
Last week I wrote about getting Started with Spring Cloud Data Flow. This week I want to show you a few more things that you can do with this amazing platform. In this article I will show you how to make your own Apps that can be part of Data Flow Streams and how to use the Data Flow Shell to control the platform. Continue reading “Spring Cloud Data Flow – Making Custom Apps and Using Shell”
In this article, I will show you how you can get started with Spring Cloud Data Flow. Spring Cloud Data Flow is an amazing platform for building data integration and processing pipelines. It has a very user-friendly graphical dashboard where you can define your streams, making your work with data an absolute pleasure. Continue reading “Getting Started with Spring Cloud Data Flow”
One of the challenges in building distributed system is having a good visibility of what is happening inside them. This challenge is only magnified when dealing with choreography- microservices, loosely coupled, communicating via messaging. In this article you will see how Sleuth and Zipkin help to solve that problem.
When dealing with messaging in a distributed system, it is crucial to have a good method of handling bad messages. In complicated systems, messages that are either wrong, or general failures when consuming messages are unavoidable. See how you can deal with this problem using Dead Letter Queues, RabbitMQ and Spring Boot Cloud. Continue reading “Handling bad messages with RabbitMQ and Spring Cloud Stream”
With Spring Boot 2.0 release just around the corner (at the time of writing we have RC1) it is important to see what changes it brings. Even if you are not planning to migrate shortly, it is good to see what is new in this biggest Spring Boot release since the 1.0 version. In this blog post I won’t go through every detail, but cover the most important things. Continue reading “What you need to know about Spring Boot 2.0 (RC1)”
Message queues are very important and useful tools that you can utilize for for your Microservices oriented architecture. Many developers are hesitant using them with the fear that they may add too much complexity and learning curve to understanding of their system. I will show you how to make use of RabbitMQ and Spring Cloud Stream to get some basic messaging routes set-up with a very little effort!
