In today?s world, every customer is thinking of agility, parallel development and reducing cost, especially infrastructure cost and operational cost. We have seen SOA world where we have written code and multiple services talk to each other?s for a business use case, but sometimes we end up with one big code base which is monolithic in nature and maintenance is becoming difficult. We have seen customers are using cloud and paying for on-demand services without effectively utilizing resources. These problems invite micro-services. In this paper, I am going to discuss how one should use micro-service in a production environment and local machine, how to scale, monitor and support Blue-Green deployment.
