Cloud computing is an emerging computing paradigm, which enables an on-demand and scalable provision of computing resources. Cloud computing is increasingly gaining industrial acceptance due to its flexibility, efficiency and its ability to reduce the costs for the Cloud users. Cloud computing provides an efficient solution for hosting non-critical IT services, but it does not yet meet the telecom and critical real-time applications requirements in terms of dependability and high availability. Major Cloud providers, such as Amazon, just ensure the availability of the virtual resources they are offering as a service. From the perspective of the Cloud tenants, the main concern is the high availability of their applications deployed in the Cloud. The first objective of this research project is to define a high availability solution that bridges this gap between the Cloud users' aspirations and the Cloud providers' offerings. In the context of Cloud computing, high availability imposes certain requirements that are conflicting with the Green computing, which aims at an efficient resource utilization and reduction of the environmental footprint of the Clouds. In particular, while high availability favors redundancy and the use of standby entities to eliminate single points of failures, Green computing encourages the consolidation of resources to maximize utilization. This introduces a multi-dimensional optimization problem. The second objective of this research project is to incorporate Green-awareness into the HA solutions defined to achieve the first objective.

云计算是一种新兴的计算模式，它能够按需和可扩展地提供计算资源。云计算因其灵活性、效率以及降低云用户成本的能力而越来越受到业界的认可。云计算为托管非关键IT服务提供了一种有效的解决方案，但它在可靠性和高可用性方面尚未满足电信和关键实时应用程序的要求。主要的云提供商，如亚马逊，只是确保他们作为服务提供的虚拟资源的可用性。从云租户的角度来看，主要关注的是部署在云中的应用程序的高可用性。本研究项目的第一个目标是定义一个高可用性解决方案，以弥合云用户的愿望和云提供商的产品之间的差距。在云计算的背景下，高可用性强加了某些与绿色计算相冲突的要求，绿色计算的目的是有效地利用资源并减少云的环境足迹。特别是，虽然高可用性有利于冗余和使用备用实体来消除单点故障，但绿色计算鼓励整合资源以最大化利用率。这引入了多维优化问题。本研究项目的第二个目标是将绿色意识纳入为实现第一个目标而定义的HA解决方案中。
