SLA@SOI Demo: Open Reference Demonstrator - Create Agreement Scenario

Open Reference Demonstrator is used as an open source demonstrator highlighting features provided by the SLA@SOI framework. The ORD demonstrates the use of the SLA management framework in the context of a service-oriented retail solution (application called Open Reference Case) supporting the sales process in supermarkets. More in detail, the ORC includes IT support for retail chains in general, covering enterprise headquarters (central management issues), stores (local management) and cash desks. Several shop providers, each with a certain number of stores, are connected to a single service provider, supporting sales of goods with an IT system. The ORC software can run on a virtualized infrastructure using various deployment options, to cover small as well as large shops with different requirements regarding the performance of the system.

SLA@SOI framework is an SLA-management framework offering four main novelties: (1) the architecture supports multi-layered SLA management where SLAs can be composed and decomposed along functional & organizational domains; (2) it supports arbitrary service types (business, software, and infrastructure) and SLA terms; (3) the architecture covers the complete SLA and service lifecycle with consistent interlinking of design-time, planning and run-time management aspects; (4) the actual implementation supports flexible deployment setups, where actual components can be flexibly selected, extended and connected and where founding data models can be extended.

The framework's architecture mainly focuses on separation of concerns, related to SLAs and services on the one hand, and to the specific domain (e.g., business, software, and infrastructure) on the other. Service Managers are responsible for all management activities directly related to services. This includes the management of information about available services, supported types of services, as well as their offered functionality and their dependencies. SLA Managers are responsible for all actions that are related to the service-level agreements. They are involved in the negotiation with customers and they are responsible for the planning and optimization of new services that are to be provisioned. Furthermore, they monitor the terms a provider and customer have agreed upon and react in case of violations. The provisioning of a service is a joint effort of all SLA Managers and Service Managers involved. In order to support multiple domains with our framework, multiple SLA managers and multiple Service Managers can collaborate inside the framework as well as across framework boundaries. Thereby, each SLA Manager and Service Manager is responsible for SLAs and services of a particular domain.
