Multi-tenancy in cloud-native architecture: a systematic mapping study

Cloud-native architectures has become an essential part of the cloud computing paradigm with the capacity of improved horizontal and vertical scalability, automation, usability and multi-tenancy. However, there are parts that are yet to be fully discovered like multi-tenancy. Multi-tenancy an essential part of the cloud computing, has not been fully. The purpose of this study is to survey existing research on multi-tenancy in cloud-native architecture in order to identify useful trends, opportunity, challenges and finally the needs for further researches. A systematic mapping method was used to systematically compare, classify, analyse, evaluate and appraise existing works of literature on multi-tenancy in cloud-native. We started from over 921potentially relevant peer reviewed publications. We applied a selection procedure resulting in 64 peer reviewed publications over the last six years between 2015 to 2022 and the selected studies were classified through the characterisation framework. The review shows the emerging challenges and trending concepts in multi-tenancy within cloud native architecture, but also discusses the improvement in multi-tenancy while considering cloudnative architecture in the recent years.
