Abstract: In monolithic systems replacement, microservices are being exploited as a natural solution. For improving the microservices in cloud technology, some specific technologies and standards have been considered, such as REST and API, on a massive scale for practical implementation. This paper is presented with a bibliographic survey on the architecture of microservice that focuses on privacy, security, and aspects of standardization in cloud computing environments. Based on microservices, different kinds of elements should be considered to determine the solutions effectively.
