title: Increasing Scalability of a microservice based system
body: <p>I am using KAFKA to get the data from a source.
  I want to know that if I increase the number of component serially in the microservice architecture, will it make it more scalable? Or just increasing the number of KAFKA consumers of same component type will increase it? 
  PS: Sorry for any mistake, I am posting a question for the first time.</p>
