In the recent years, cloud computing has proved to be the ideal platform for hosting large-scale Internet applications. As a result, there is a pressing need to further develop cloud infrastructures and services and enhance their agility, cost-effectiveness, performance and availability. Emergent technologies like Network Function Virtualization (NFV) and Software Defined Networking (SDN) hold great promise to fulfill this need as they allow to dynamically build services as chains of Virtual Network Functions (VNFs) that are easily inter-connected using SDN capabilities.This project aims at designing scalable, efficient and dynamic cloud management frameworks for futuristic infrastructures able to satisfy requirements of large-scale Internet applications in terms of performance and availability while minimizing operational costs. This requires devising novel resource allocation schemes to manage NFV-based services and designing cloud architectures able to leverage the flexibility of SDN without incurring its potential limitations. Specifically, we intend to investigate the following key challenges:(1) Design and Management of VNF-based Cloud Services: with the success of virtualization technology, recent proposals have advocated to virtualize network functions (e.g., firewalls, routing) and offer them as VNFs to build Internet services. In this context, we intend to address challenges related to the dynamic provisioning of NFV-based services with the goal of ensuring their performance and reducing operational costs.(2) Availability-aware management in the Cloud: today's cloud users are expecting stringent guarantees on the availability of their services. However, there are currently no accurate and efficient techniques to evaluate the availability of a service running on the cloud. We therefore plan to develop models able to evaluate service availability and leverage them to design a new generation of availability-aware resource allocation schemes that satisfy the desired availability while minimizing the incurred costs.(3) Design and Management of SDN-based Cloud Infrastructures: SDN technology has recently emerged as a new paradigm offering the programmability required to dynamically configure cloud networks. Despite its benefits, the traditional SDN architecture suffers from scalability limitations. We therefore intend to investigate the challenges associated with the design of a novel SDN-based architecture that overcomes these limitations while keeping SDN benefits.The outcome of this project is expected to make significant contributions in developing novel architectures and management frameworks for next-generation cloud infrastructures and services. This project is also an excellent opportunity for graduate students to acquire expertise in technologies like NFV and SDN which are gaining significant momentum in industry and academia.

近年来，云计算已被证明是托管大规模互联网应用的理想平台。因此，迫切需要进一步发展云基础设施和服务，提高其敏捷性、成本效益、性能和可用性。网络功能虚拟化(NFV)和软件定义网络(SDN)等新兴技术为满足这一需求提供了巨大的希望，因为它们允许动态地将服务构建为使用SDN能力轻松互连的虚拟网络功能链(VNF)。该项目旨在为未来基础设施设计可扩展、高效和动态的云管理框架，以满足大规模互联网应用在性能和可用性方面的要求，同时将运营成本降至最低。这需要设计新的资源分配方案来管理基于NFV的服务，并设计能够利用SDN的灵活性而不会招致其潜在限制的云架构。具体地说，我们打算调查以下关键挑战：(1)基于VNF的云服务的设计和管理：随着虚拟化技术的成功，最近的提案主张将网络功能(如防火墙、路由)虚拟化，并将其作为VPN提供以构建互联网服务。在这种情况下，我们打算解决与基于NFV的服务的动态配置相关的挑战，以确保其性能和降低运营成本。(2)云中的可用性感知管理：今天的云用户期望对其服务的可用性提供严格的保证。然而，目前还没有准确有效的技术来评估在云上运行的服务的可用性。因此，我们计划开发能够评估服务可用性的模型，并利用它们来设计新一代可用性感知资源分配方案，在满足所需可用性的同时最大限度地减少所产生的成本。(3)基于SDN的云基础设施的设计和管理：SDN技术最近作为一种新的范例出现，提供动态配置云网络所需的可编程性。尽管有好处，传统的SDN体系结构仍受到可伸缩性限制。因此，我们打算调查与基于SDN的新型架构的设计相关的挑战，以克服这些限制，同时保持SDN的优势。该项目的成果有望为开发新一代云基础设施和服务的新型架构和管理框架做出重大贡献。这个项目也是研究生获得NFV和SDN等技术专业知识的绝佳机会，这些技术在工业界和学术界获得了巨大的发展势头。
