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. I even added a disclaimer to tell my contacts in Linkedin that I will not be leaving Java while joining Microsoft 😂 I will be back to this point later. ...

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 🤓 ...

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. ...

January 2018, Red Hat acquired CoreOS for 250 million dollars 🤩. CoreOS was one of the leading companies of Linux & Containers market with their wide offer of products: CoreOS Tectonic: container application platform based on Kubernetes. CoreOS Container Linux: lightweight Linux distribution designed to run containerized applications. CoreOS Operators Framework: an open source toolkit designed to manage Kubernetes native applications. CoreOS Quay: a container registry for building, storing, and distributing your private containers. CoreOS rkt: an application container engine developed for modern production cloud-native environments. even more and more.. Red HatOpenShift 3.x was facing many big problems especially in installations and upgrades. It was a real nightmare to install an OCP Cluster. I never heard an OCP Admin talking about upgrading OCP without discussing the problems that they faced. Personally, I worked for two customers from 2017 to 2019 that adopted OCP, and when it comes to cluster upgrades they were dedicating time and they were bringing people from Red Hat to help them do that 😂 Although, the upgrades were guaranteed by Red Hat in all technical and commercial announcements. ...
