Background: SaaS (Software as a Service) is a services delivery model in Cloud Computing whose applications are remotely hosted by the service provider and available to customers on demand over the Internet. Multi-tenant Architecture (MTA) is an organizational pattern for SaaS that enables a single instance of an application to be hosted on the same hardware and accessed by multiple customers, so-called tenants, with the aim of lowering costs. Tenants are able to configure the system according to their particular needs. Objective: This research aims at the obtaining an overview of the challenges and research opportunities in MTA context for SaaS through a Systematic Mapping Study. Results: Eighty nine primary studies were selected for discussions on advances and opportunities for further investigations. The results showed the relevancy of MTA and pointed out the main research trends for next years in this topic.
