Today is my birthday and what a wonderful day to celebrate my life, but not only. Today I celebrate my first year in Microsoft, one of the most wonderful years in my career.. a year plenty of great new people, amazing challenges, wellness and happiness. 🎉🎊 When I started working for Microsoft last year, I was the Java developer joining the .Net Gurus town. It was a very exceptional situation for my Java friends, because since I started working in 2012, I was always dealing with the open source world, and Microsoft at that time wasn’t in the same planet as us....

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. One of the most used Messaging solutions is Apache Kafka: Kafka is an open-source stream-processing software platform developed by LinkedIn and donated to the Apache Software Foundation, written in Scala and Java. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds....

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. Great gift 😍 The workshop was done on 21 Hours of training about Java, Spring Boot, DDD, Docker, Kubernetes, Cloud Patterns, Azure AKS & Functions… Some Github repositories used in the sessions: Monolith Example Microservices Examples Speaker Deck The event was sponsored by Microsoft 😍🤩🥳 !...

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 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 workshop content: Part 1: The Monolithics Era Part 2: Coding the monolith Part 3: Microservices Era Part 4: Applying DDD to the code Part 5: Meeting & Implementing the µservices concerns and patterns Part 6: Building the standalone µservices Part 7: Packaging µservices in containers Part 8: Falling in 🥰 with container orchestrator: KUBERNETES 😍 Part 9: Applying the Kubernetes Style Part 10: Meeting Azure ☁️ Part X: What ’s next ?...

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 ?...

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. The Docker racing was accelerated by the presence of Kubernetes in the market, which is coming with an amazing set of great features....

The serverless architecture became one of the most buzzy words nowadays. Almost all the cloud providers have a Serverless platforms in their catalogues: Microsoft Azure Functions Amazon Web Services Lambda Google Cloud Functions IBM Cloud Functions Oracle Functions In an other world, there are many solutions to have a Serverless Runtime into Kubernetes, which is the most popular (and the most wonderful) container orchestrator in the market. These solutions are so helpful especially if you need portability for your functions....

In some previous articles, I was writing about the Azure Functions, which is the Microsoft Serverless solutions. After joining Microsoft, I got the chance to work on this great product for many business cases and I found it was really great 🥳 Recently, one of my Facebook friends asked me to write a blog post about what is Serverless architecture ? 🤔 what is for ? 🤔 and especially, what are the scenarios that are not suitable for Serverless ?...

In this tutorial, we will be experimenting a new use case of the great Azure Functions service 😁 one of my favorite products in Azure. In this tutorial, we will bring the powerful features of the Spring Framework to our Azure Functions Java projects. After this tutorial, creating a new Azure Functions Java based on business logic that you already have in your Spring Boot Application will be a very easy game....
