Over the last decade, the microservice architecture has become a standard
for big and successful internet companies, like Netflix, Amazon and LinkedIn.
The importance of stream processing, aggregation and exchange of data is
growing, as it allows companies to compete better and move faster. In this
diploma, we have analyzed the interactions between microservices, described
the streaming platform and ordinary message queues. We have described
the Apache Kafka platform and how it works. We have developed the KumuluzEE
Event Streaming extension for the Java platform that allow easy
integration of event streaming and microservices. With the use of the extension,
you can easily implement the Kafka platform in our microservice
system. Our extension provides easy to use annotations for producing, consuming
messages and stream processing. As a proof of concept, we have
developed a sample bookstore application. It has been designed in the event
driven microservice architecture with the use of event sourcing and CQRS
patterns.
