  • Patent number: 10261872
    Abstract: Account data comprising metadata for primary application instances running at a primary active cloud environment instance (ACEI) is stored. Application data associated with the primary application instances is stored at primary databases (DBs). The account and application data are transferred to secondary DBs at a secondary ACEI. The secondary ACEI may be a backup instance to substitute services provided by the primary ACEI in case of unavailability. For example, the location where the primary ACEI is hosted may be affected by a disaster. To failover a primary data center hosting the primary ACEI, a database takeover to the secondary DBs is performed. The secondary ACEI is configured correspondingly to the primary ACEI based on the transferred account data. Secondary application instances corresponding to the primary application instances are started at the secondary ACEI. Requests directed to the primary application instances are redirected to the secondary application instances.

  • Patent number: 10067808
    Abstract: A resource registry provides nondeterministic operation environment affording flexible access for resource execution and status monitoring on the cloud. The resource registry service provides generic resource management utilizing registration, updating, and unregistration by resource providers. A requester for an operation may register in the resource registry, an operation resource having parameters defined in metadata. The resource registry notifies a registered resource listener of this registration of the operation resource. The resource listener may then execute the operation according to parameters defined in the operation resource. The resource listener returns a response to the resource registry, concerning a result of execution of the operation. The resource registry updates this status in the metadata of the operation resource. The requester is then able to look up the operation resource's metadata to determine current status of the operation.
