Abstract: A new paradigm that is paving the way for many methods and standards is the cloud. Due to the demands of the cloud, architectural styles are also changing. Microservices are now regarded as the preferred design for scalable, quickly changing cloud systems. A thorough mapping study of microservices was conducted for this research. It aims to identify current microservices trends, the driving force behind microservices research, upcoming standards, and potential research needs. Researchers and practitioners in the field of software engineering who want to be informed of emerging trends regarding SOA and cloud computing can benefit from the results that have been collected.
