Microservices allow us to go faster and reduce our time to value. However, we cannot just naively move fast and break things. We need a way to reduce the risk of making changes and in doing so, make it safer to bring new changes to production. A powerful pattern that helps lower risk of bringing changes into production is to ...

Back in 2015 I wrote a couple of articles about how you can piggyback a standard Java EE Transaction Manager to get data consistency across distributed services (here is the original article and here is an article about doing it with Spring Boot, Tomcat or Jetty). Last year I was fortunate enough to work on a small project where we ...

We’ve been talking about Istio and service mesh recently (follow along @christianposta for the latest) but one aspect of Istio can be glossed over. One of the most important aspects of Istio.io is its ability to control the routing of traffic between services. With this fine-grained control of application-level traffic, we can do interesting resilience things like routing around failures, ...

When we build services architectures (Service Oriented Architecture, Microservices, the next incarnation, etc), we end up making a lot more calls over the network. The network is perilous. We try to build redundancy into our services so that we can experience failures in our system and still move forward and process customer requests. An important part of this puzzle of ...

As you progress in your education as a developer, you will sooner or later understand the benefits that a container system like Docker has to offer: you can specify your environment in code, without all the Slack messages to system engineers or the headaches that go into standing up consistently provisioned servers. Likewise, you have probably understood the appeal of ...

In a world of numerous programming trends, companies are starting to boast about how they’re becoming “cloud native.” This declaration might seem full of hot air and pretension, however, there’s a huge value to embracing what cloud native truly is. In short, cloud native is an approach to creating and deploying applications that fully taps into the advantages of delivering, ...

One of the main aspects of microservices architecture is that the application is formed as a collection of loosely coupled services each one deployable independently and communicated each other with some kind of light protocol. It is because of microservices architecture is a distributed system that makes writing end to end tests really hard. Suppose next simple example provided by ...

1. Introduction We have already been through the Microservice demo and it was so pleasing to see the wonderful response it received. Hopefully we are all good with the basics now. This tutorial will guide us all through the actual Microservices implementation, so we are well-directed every time we are asked to create it. 2. Understanding Service Registry Traditionally, when ...

Challenges & opportunities for cloud-native applications Current technology landscape for cloud-native apps is evolving and Platform-as-a-Service (PaaS) solutions are constantly changing to meet the demands such architecture. As customers need flexibility and openness in terms of choosing PaaS solution (without any vendor or technology lock-in), a key need is to provide a neutral view in terms of: Which PaaS solution ...
