Cloud resource orchestration: A data-centric approach

摘要: Cloud computing provides users near instant access to seemingly unlimited resources, and service providers the opportunity deploy complex information technology infrastructure, as a service, their customers. Providers bene t from economies of scale multiplexing gains orded by sharing resources through virtualization underlying physical infrastructure. However, highly dynamic nature cloud platforms impose signi cant new challenges providers. In particular, realizing sophisticated services requires control framework that can orchestrate resource provisioning, con guration, utilization decommissioning across distributed set resources. this paper we advocate data-centric approach orchestration. Following approach, are modeled structured data be queried declarative language, updated with well-de ned transactional semantics. We examine feasibility, ts present our design prototype implementation Data-centric Management Framework (DMF) solution, models, query languages semantics speci cally designed for
