How to learn Spring Cloud – the practical way

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.

Introducing JSON-B with Spring Boot 2.0

JSON Binding (JSON-B) is the new Java EE specification for converting JSON messages to Java Objects and back. JSON is used everywhere and so far we had two main ways of dealing with JSON conversion in Java- using either Jackson or GSON. With the introduction of JSON-B, we have a standard way of handling this conversion. In this article, we will see how Spring Boot 2.0 supports JSON-B, how easy it is to use it and how does it compare with the other options. Continue reading “Introducing JSON-B with Spring Boot 2.0”

Spring Cloud Data Flow – Use Cases

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”

Spring Cloud Data Flow – Making Custom Apps and Using Shell

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”

Building services requires building teams

When talking about microservices (or agile development), the idea of self-managed, independent teams often comes up. What is not emphasized enough is how vital this idea is to the successful adoption of such highly decoupled architecture. In this article, I will share my experiences about working with independent teams and being part of them. Continue reading “Building services requires building teams”

Getting Started with Spring Cloud Data Flow

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”

HATEOAS – a simple explanation

HATEOAS – Hypermedia as the Engine of Application State, a name long enough to intimidate and confuse. Behind this complicated name we have a rather simple and elegant idea. In this blog post, I explain what HATEOAS is and how it can be practically used to build more stable systems. Continue reading “HATEOAS – a simple explanation”

Application of GRASP to Microservices

GRASP stands for General responsibility assignment software patterns. You might have heard of it before, or you might not. Either way, you might not have thought about how these principles can potentially help when deciding your responsibilities assignments in a microservices architecture. Craig Larman in his book Applying UML and Patterns said that the “desert island skill”, the most important skill to have in Object Oriented Analysis/Design would be: “to skillfully assign responsibilities to software objects”. I think there is some truth to this when thinking about the most important microservices skill as well. Lets look at GRASP through the prism of microservices. Continue reading “Application of GRASP to Microservices”
