“…Consequently, a microservice must be capable of working with a plethora of different technologies, a concept called polyglot microservice [43]. Thus, several database systems can be used in a microservice architecture, like Cassandra [57], InfluxDB [136,147], MySQL [55,78], MongoDB [18,29]. Moreover, the microservices are developed using different programming languages and frameworks such as, Python [55,78,79,146,136,81,139,54,140,142,121,28], Java OSGi [110,125], SpringBoot [71,146,115], Java [41,29,79,128,53,94], Golang [18,146,84], Node.JS [125,137], C++ [78,79,140], R [17], and even pure C [126].…”
