摘 要：For companies deploying and proposing cloud computing offers as Infrastructure as a Service,data replication and storage mechanisms remain the de facto prerequisite to ensure bothintegrity and service continuity for their customers. Cloud computing offers a model in which thelocation of data is not as important as in other models of infrastructures (such as those in whichthe company directly owns expensive storage hardware). Ceph is an open source, unified,distributed storage system that offers a convenient way to deploy a low-cost and massivelyscalable storage platform with commodity hardware. Discover how a Ceph cluster — presentingobject, block, and file storage from a single point — is created, its algorithms and replicationmechanism, and how it can be integrated with your cloud data architectures and models. Theauthor proposes a simple, yet powerful approach for integrating the Ceph cluster within anOpenStack ecosystem.
