The shift from monolithic to micro services architecture has been remarkable. Micro services have emerged to be an effective and efficient architecture pattern for various applications and have become a preferred choice for efficient and rapid development of distributed applications. Micro services follow a decentralized approach where each service has an individual outcome and communicates with other services. This communication is carried out with the help of a well-designed set of protocols which are known as Application Programming Interfaces (API). It is seen that micro service architecture is used popularly for cloud applications. But apart from cloud applications, micro services along with block chain, internet of things (IoT), machine learning, and other domains have varied use cases. This paper tries to emphasize the importance of the micro services architecture in these domains. We also provide an overview of the research carried out in these fields along with some of the real time use cases of micro services.
