Model-based high availability configuration framework for cloud

Since cloud computing has emerged as a commercial reality, guaranteeing high availability (HA) has become a critical requirement. Many kinds of HA mechanisms have been developed with the rapid expansion of cloud computing. However, selection and configuration are difficult in practice. In the development phase, developers must choose HA mechanisms for cloud computing based on their experience. In the use phase, users must choose and configure the HA mechanisms for their virtual machines (VMs) or services deployed on VMs. In this paper, we proposed a model-based HA configuration framework for the cloud. For the developer, we proposed an open HA mechanism library and an automatic configuration process. For users, we intend to ease the selection of HA mechanisms in the ever-changing cloud environment. We are implementing our approach in our model-based cloud platform, JadeCloud. ? 2013 ACM.EI
