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.

An other great #PlayingWith Series Workshop about Java Microservices and Kubernetes
Playing with Java from 9 to 13
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 😁
New #PlayingWith Series Workshop about Java Microservices and Kubernetes - ENSI 2020
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.
Playing with CQRS and Event Sourcing in Spring Boot and Axon
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 🤓
Playing with JVM inside Docker Container
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.
New #PlayingWith Series Tutorial about Serverless architecture in Kubernetes
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. For example, you can have the same Serverless Runtime deployed to Azure Kubernetes Service and Google Kubernetes Engine. You can be deploying the same binaries as functions identically to both of the cloud providers.
In this tutorial, I will demonstrate how to deploy a Serverless Framework to Minikube and on which we will deploy some Functions based on Spring Boot Framework.
A new #PlayingWith Series Tutorial about Azure Functions and Spring Cloud
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.
New #PlayingSeries tutorial about Java Azure Functions
In one of the previous posts, I introduced the Azure Functions Java. I felt that I need to write a dedicated tutorial to this great Azure Serverless service 😁
In this post, I will be covering many concepts in deep:
- Triggers and bindings
- Events and messaging
- Deployments & Consumptions
- Monitoring
Many thanks for JetBrains for the great gift ! 😍
I would like to thank JetBrains for offering me the complimentary JetBrains All Products Pack subscription as part of the JetBrains Developer Recognition Program 🤩
Say hello to my IntelliJ IDEA Ultimate
A new #PlayingSeries tutorial showing how to use some Azure Monitor services with Spring Boot
In enterprise application, performance is major requirement of success. Especially for applications where slowness will have a direct detrimental impact on business productivity, profits and even the brand itself, like trading platforms and e-commerces.
If a trading platform loads slowly or experiences errors, it will translate into loss of business, and losses can be extremely high, and the customer might end up switching to another competitor.
In this context comes the Application Performance Management (APM). APM is the monitoring and management of performance and availability of applications. APM strives to detect and diagnose complex application performance problems to maintain an expected level of service.
On this article, I am going to explain how to use Azure Monitor which is the Microsoft Azure’s product that helps you maximize performance and availability of your applications and proactively identify problems in seconds.
