  • Publication number: 20140304334
    Abstract: An improved scalable object storage system includes methods and systems allowing multiple clusters to work together. Users working with a first cluster, or with a multi-cluster gateway, can ask for services and have the request or data transparently proxied to a second cluster. This gives transparent cross-cluster replication, as well as multi-cluster compute or storage farms based upon spot availability or various provisioning policies. Vendors providing a cloud storage “frontend” can provide multiple backends simultaneously. In one embodiment, a multi-cluster gateway can have a two, three, or higher-level ring that transparently matches an incoming request with the correct cluster. In the ring, a request is first mapped to an abstract “partition” based on a consistent hash function, and then one or more constrained mappings map the partition number to an actual resource. In another embodiment, the multi-cluster gateway is a dumb gateway, and the rings are located only at the cluster level.

  • Patent number: 8775375
    Abstract: An improved scalable object storage system includes methods and systems allowing multiple clusters to work together. In one embodiment, there is a multi-cluster synchronization system between two or more clusters. The multi-cluster synchronization system uses variable compression to optimize the transfer of information between the clusters. Compression is used not only to minimize the total number of bytes sent between the two clusters, but to dynamically vary the size of the objects sent across the wire to optimize for higher throughput after considering packet loss, TCP windows, and block sizes. This includes both the packaging of multiple small files together into one larger compressed file, saving on TCP and header overhead, but also the chunking of large files into multiple smaller files that are less likely to have difficulties due to intermittent network congestion or errors.

  • Publication number: 20140108474
    Abstract: A system for exposing data stored in a cloud computing system to a content delivery network provider includes a database configured to receive and store metadata about the data, the database being implemented in the cloud computing system to store configuration metadata for the data related to the content delivery network, and an origin server configured to receive requests for the data from the content delivery network provider, and configured to provide the data to the content delivery network provider based on the metadata.

  • Publication number: 20120233118
    Abstract: An improved scalable object storage system allows multiple clusters to work together. In one embodiment, a multi-cluster synchronization system synchronizes data between two or more clusters. Each cluster has a cluster-internal network, with object storage services and container services. The container services track and replicate metadata associated with the object storage service. An intercluster network connects the two clusters and performs a one-way synchronization of the objects and metadata associated with a particular container. In a further embodiment, multiple synchronization relationships can be set up, either in a cycle (with two or more participants), in a line, or in a tree. For example, the multi-cluster replication could be used to transparently synchronize objects in a CDN network.

  • Publication number: 20120233668
    Abstract: In one embodiment, a cloud computing system provides user extensibility by providing a plugin interface for major systems. Plugin interfaces for a compute service, object service, network service, authentication and authorization service, message service, and image service are disclosed. One or more of the plugin interfaces can be used to alter the allocation of virtual to physical resources across multiple services. Compound services and smart allocation facilities are possible with user-directed modification.

  • Publication number: 20120233463
    Abstract: An improved scalable object storage system allows multiple clusters to work together. In one embodiment, a trust and federation relationship is established between a first cluster and a second cluster. This is done by designating a first cluster as a trust root. The trust root receives contact from another cluster, and the two clusters exchange cryptographic credentials. The two clusters mutually authenticate each other based upon the credentials, and optionally relative to a third information service, and establish a service connection. Services from the remote cluster are registered as being available to the cluster designated as the trust root. Multi-cluster gateways can also be designated as the trust root, and joined clusters can be mutually untrusting. Two one-way trust and federation relationships can be set up to form a trusted bidirectional channel.
