it seems kafka is not needed for creating cloud native application

[loveyandex]

I see we can develop any system with distributed database and restful connected systems to it

so natively any restful system is stateless and scalable it easy and for mangaing we can use a manger for add and remove node

so kafka where and how to use
where we can find it in open soyrce
