Creating good distributed applications is not an easy task: such systems often follow the 12-factor app and microservices principles. They have to be stateless, scalable, configurable, independently released, containerized, automatable, and sometimes event-driven and serverless. Once created, they should be easy to upgrade and affordable to maintain in the long term. Finding a good balance among these competing requirements with ...

Modernizing and improving a team (and eventually an organization’s) velocity to deliver software-based technology is heavily influenced by it’s people, process and eventual technology decisions. A microservices approach may be appropriate when the culmination of an application’s architecture has become a bottleneck (as a ...

Microservices in Publish-Subscribe communication using Apache Kafka as a Messaging Systems and validated through Integration Test

Publish-Subscribe Messaging systems play an important role in any enterprise architecture as it enables reliable integration without tightly coupling the applications. The ability to share data between decoupled systems is not a problem that is easily tackled. Consider an enterprise with multiple applications that are being built independently, with different languages and platforms. It needs to share data and processes ...

Spring Boot Microservices , Docker and Kubernetes workshop – part3

In the previous posts we build few micro services (Order Service, Product Service, Customer Service) for an order management system using Docker and Spring Boot. We used Netflix libraries to manage, discover and load balance the micro services. Managing these micro services and their multiple containers could get a bit tricky; especially in terms of Scalability, Observability, Security, Monitoring and ...
