“…To execute the business processes in the service network, the software engineers at RoSAS design, enact, and manage it using a software framework (e.g., SDSN [3]). For a new tenant, a software engineer creates a VSN in the service network to meet the functional and performance requirements of the tenant.…”

“…In the second case, a subset of interactions produced by one collaboration will be consumed by other collaborations, and vice versa. To capture the routing and regulation of these inter-collaboration interactions, we use the concept (abstraction) of inter-collaboration regulation units (as in SDSN [3]). Similar to the realization of a collaboration, these units are also manifested in the service network as a set of regulation table entries.…”

“…The interactions between the services over the service network are regulated by the contractual relationships that exist between them. A service network can use the single instance multi-tenancy (SIMT) model [4] to share itself between different tenants to reduce operational cost of managing different service network variants for tenants, and improve utilization of the capacities of services [3]. The result is a multi-tenant service network, where a set of virtual service networks (VSNs) simultaneously coexist on the same service network in a way analogous to virtual computer networks.…”

“…This paper presents FM4SN (Feature Models for Service Networks), a tenant-oriented customization approach and framework for multi-tenant service networks. We base our work on the Software-Defined Service Networks (SDSN) [3] approach that supports the design, enactment, and management of multi-tenant service networks. In SDSN, a service network (the application) is a runtime model (models@runtime [5]) that acts as an overlay network over the services.…”

In a multi-tenant service network, multiple virtual service networks (VSNs), one for each tenant, coexist on the same service network. The tenants themselves need to be able to dynamically create and customize their own VSNs to support their initial and changing functional and performance requirements. These tasks are problematic for them due to: 1) platform-specific knowledge required, 2) the existence of a large number of customization options and their dependencies, and 3) the complexity in deriving the right subset of options. In this paper, we present an approach to enable and simplify the tenant-driven customization of multi-tenant service networks. We propose to use feature as a high-level customization abstraction. A regulated collaboration among a set of services in the service network realizes a feature. A software engineer can design a customization policy for a service network using the mappings between features and collaborations, and enact the policy with the controller of the service network. A tenant can then specify the requirements for its VSN as a set of functional and performance features. A customization request from a tenant triggers the customization policy of the service network, which (re)configures the corresponding VSN at runtime to realize the selected features. We show the feasibility of our approach with two case studies and a performance evaluation.

SDSN@RT: A middleware environment for single‐instance multitenant cloud applications

With the single-instance multitenancy (SIMT) model for composite Software-as-a-Service (SaaS) applications, a single composite application instance can host multiple tenants, yielding the benefits of better service and resource utilization and reduced operational cost for the SaaS provider. An SIMT application needs to share services and their aggregation (the application) among its tenants while supporting variations in the functional and performance requirements of the tenants. The SaaS provider requires a middleware environment that can deploy, enact, and manage a designed SIMT application, to achieve the varied requirements of the different tenants in a controlled manner. This paper presents the SDSN@RT (software-defined service networks at runtime) middleware environment that can meet the aforementioned requirements. SDSN@RT represents an SIMT composite cloud application as a multitenant service network, where the same service network simultaneously hosts a set of virtual service networks, one for each tenant. A service network connects a set of services and coordinates the interactions between them. A virtual service network realizes the requirements for a specific tenant and can be deployed, configured, and logically isolated in the service network at runtime.SDSN@RT also supports the monitoring and runtime changes of the deployed multitenant service networks. We show the feasibility of SDSN@RT with a prototype implementation and demonstrate its capabilities to host SIMT applications and support their changes with a case study. The performance study of the prototype implementation shows that the runtime capabilities of our middleware incur little overhead.
