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 Azure Monitor services and 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.

Playing with Istio Service Mesh on Kubernetes

What is Istio?

Google presents Istio as an open platform to connect, monitor, and secure microservices.

Istio is a service mesh implementation that provides many cloud-native capabilities like:

  • Traffic management: Service Discovery, Load balancing, Failure recovery, A/B testing, Canary releases, etc…
  • Observability: Request Tracing, Metrics, Monitoring, Auditing, Logging, etc…
  • Security: ACLs, Access control, Rate limiting, End-to-end authentication, etc…

Istio delivers all these great features without any changes to the code of the microservices running with it on the same Kubernetes cluster.

In our case, we already implemented many of these features and capabilities when we were writing our microservices. If we had Istio at the beginning, we could save so much effort and time, by delegating all of these capabilities to Istio.
