Quarkus is one of the current trends of the Java ecosystem. I’m already in love with it. I’m using it along with Spring Boot, and when I choose, I choose Quarkus. 😁
This week, I was working on a Batch POC using Azure Functions and Azure Automation. So I thought it will be useful to share the exercise with you. 😁
Today is the big day 🥳🥳 My third book “Playing with Java Microservices with Quarkus and Kubernetes” is available in Early Access 🎉🎊🎈✨
Today, I will not be sharing a tutorial or a review, I will share with you my new book news ! 🥳 I just finished typing the fourth chapter. These four chapters belong to the first part of the story: the MoNoLITHiC dedicated part 🤪 ..
Reactive programming ! Wow ! What a fancy buzzy word ! I waited so much to write a blog post about this trend 😃 I was waiting for the landscape to be mature to made a one-shot tutorial 😁
Today, I will show you how to make a Reactive Spring Boot application, with a Reactive CRUDs using Spring Data Reactive Relational Database Connectivity (R2DBC) with PostgreSQL and for sure the famous Webflux. Don’t be scared if you don’t know any of these topics. We will be introducing all of them smoothly ! 😊
But before digging into the practice, I will be making small story-telling about the fundamentals of the reactive programming. 😎
In an enterprise level, it’s obvious for applications to be based on messaging for communication. This is done using a middleware between these applications as a Message Bus that enables them to work together.
The workshop “Playing with Java Microservices on Kubernetes” was held from 02/01 to 04/01 – 2020, at the National School of Computer Sciences, in Manouba, Tunisia.
Since the release of Java SE 8, all the developers were under the charm of the Lambdas, Streams and even there those who fell in love with Nashorn for years (yes there are somewhere in this globe 😅).. With the crazy growth of the Enterprise Development context thru Spring Boot/Cloud, Docker, Kubernetes and the unlimited number of JS frameworks, the infinite patterns and styles of architectures, many developers lost the frequency of being up-to-date with the upstream 🤪
I was one of the unsynchronized Java developers that couldn’t get up-to-date with all this crazy new comers everyday 🥺🤯 I got the idea to write a new post, to help Java developers get upToDate Quickly on the last five Java Releases 😁
I will be in the National School of Computing Sciences of Tunisia (ENSI Tunisia), from the 2nd to 4th January 2020, to animate a 20 Hours workshop, about Microservices in Java and how to deploy them as Docker Containers to Kubernetes. The event is organized by Mrs Rim Drira.
The Microservices Architecture World, we can meet many concepts and patterns, like the Centralized Configuration, Circuit Breaker, Service Registry and Discovery, etc.. Two of these patterns are the CQRS and the Event Sourcing patterns, coming from the Domain Driven Design planet 🌏 In the most of the use-cases, these two patterns are sold together 😁 in this new tutorial, we will discover what does each one ? why they are usually used together ? and for sure we will implement these two patterns in Java ☕️ obviously 🤓
Nowadays, the most of the Java microservices and even many Java application are packaged and deployed as Docker containers. Everyone is enjoying (I hope 😆) the Docker experience, compared to the traditional VMs. But, the Docker containerization will not come alone.. nothing is autonomous 😁 So, there are many concerns to take into consideration while containerizing Java applications, like playing with the JVM.
