“…Another work [5] also finds that security and related resource isolation is a critical point in multi-tenant applications. Compared to these, the paper [6] discusses that the multi-instance approach, while being easier to implement, is better suited, if the number of tenants is likely to remain low. They state that the multiinstance model suffers from an increased maintenance cost, which can in part be attributed to the effort for deploying updates to numerous instances of the application.…”

Abstract-Full mesh is the most commonly used networking topology in Web Real-Time Communication (WebRTC) based videoconferencing (VC) applications, however, due to its inherently poor scaling capability it is not appropriate for multi-party VC with many participants. Solutions based on centralized media server infrastructures are used to leverage the scaling problem. Service providers adopting centralized approach need to ensure good resource utilization to lower the price, and at the same time provide good Quality of Experience (QoE) to the end users. In practice, even with todays advanced cloud technologies, these two conflicting goals are difficult to achieve simultaneously. In order to tackle this complex problem, we propose an innovative event-driven model, that differs from the traditional multi-tenant service provisioning model. In this work, the architecture and implementation of a WebRTC event-driven multi-party VC, based on Software as a Service (SaaS) principles is presented. A prototype was developed on top of Docker containers and Kubernetes container orchestration technologies, which in our opinion represent key enabling technologies fostering the migration from multi-tenant towards event-driven architectures. The technology readiness to support such time-critical applications is evaluated. The initial results suggest that although there are some trade-offs in terms of performance/resource consumption, our fully functional prototype allows for on-the-fly media server instance creation and destruction in arbitrary cloud provider infrastructure with still acceptable application usability.

“…Besides the requirements of shared hardware resources, shared application and shared database instance, Bezemer et al requires also high degree of configurability in look-and-feel and workflow from multitenant software [16]. Some researchers consider also multi-instancy as a form of multitenancy [14], where vendors host separate instances for each customer within shared hardware [13], [14].…”

Abstract-In the new era of computing, SaaS software with different architectural characteristics might be priced in different ways. Even though both pricing and architectural characteristics are responsible for the success of the offering; the relationship between architectural and pricing characteristics has not been studied before. The present study fills this gap by employing a multi-case research. The findings accentuate that flexible and well-designed architecture enables different pricing models; however, poorly designed architecture limits also the pricing. Scalability and high level of modularity are the major enablers of a great variety of pricing models. Using public cloud services may lead to introducing usage-based pricing or in the contrary, making the pricing simpler. Applying multi-tenancy lowers the customizability, consequently the customers' negotiation power decreases. Pricing may give special requirements to the architectural design, such as scalability, customizability and additional components.

“…Configurable applications are capable to adapt their behavior or appearance without the necessity to change the underlying implementation [11], [14] to the needs of entities (e.g., tenants, tenant users). The multi-tenant aware Service Composition Engine (SCE MT ) introduced in [12] is one example of a SCE that can be shared by different entities.…”
