Usually, I use Java with the Spring Framework (Spring Boot, Spring Data, Spring Cloud, Spring Caching, etc.) for this. Spring Boot is a framework that allows me to go through my development process much faster and easier than before. It has come to play a crucial role in my organization. As the number of our users quickly grew, we realized our apparent need for something that could process as.
Spring Cloud Stream with Kafka Overview. This sample project demonstrates how to use Spring Cloud Stream connected with Apache Kafka managed by Strimzi in a Kubernetes and OpenShift. By end of this tutorial you'll have a simple Spring Boot based Greetings microservice running that. Deploy Kafka Cluster on Kubernetes or OpenShift Cluster.
In a previous tutorial we had seen how with the Spring Cloud Config Server we have a central place to manage external properties for applications across all environments. We had stored the properties in GIT and used the same in our modules using Spring Cloud Config. Need for Spring Cloud Bus. Now consider the scenario that we have multiple applications reading the properties using the Spring.
Channel - A channel represents an input and output pipe between the Spring Cloud Stream Application and the Middleware Platform. A channel abstracts the queue that will either publish or consume the message. A channel is always associated with a queue. With this approach, we do not need to use the queue name in the application code.
We will be looking at configuration using local file system. In the next tutorial we will implement Spring Cloud Config Server using GIT Repo. Lets Begin-We will be making use of the employee-producer and the eureka-server code we developed in a previous tutorial. In this tutorial we will be-1. We will be creating a new module name employee-config-server having the externalized Eureka.
Why Spring Cloud Stream? The above is an example of an event-driven architecture, where instead of reaching out to each service one by one, our services instead emit a change of state. If a file is uploaded, our file service can emit it out to a messaging platform, and then our Super Duper Image Resizer 3000 service can listen for that and automatically generate differently sized profile images.
We are using the Spring Cloud Stream layer to configure our Kafka consumers. For example, a configuration for a processor named 'reservations-input' connected to a Kafka topic 'reservations-topic' would be similar to this.
The Spring Cloud Stream Horsham release (3.0.0) introduces several changes to the way applications can leverage Apache Kafka using the binders for Kafka and Kafka Streams. One of the major enhancements that this release brings to the table is first class support for writing apps by using a fully functional programming paradigm.
Oleg Zhurakousky and Soby Chacko explore how Spring Cloud Stream and Apache Kafka can streamline the process of developing event-driven microservices that use Apache Kafka.

With Spring's programming model and the runtime responsibilities handled by Spring Boot, it became seamless to develop stand-alone, production-grade Spring-based microservices. To extend this to Data Integration workloads, Spring Integration and Spring Boot were put together into a new project. Spring Cloud Stream was born.
