Abstract: Flexible message transformation and delivery includes authenticating a message consumer for access to messages of a publisher, receiving from the consumer a service topology label identifying a service topology of a service of which the message consumer is a part, where the service topology label is used in controlling provision of messages to members of the service topology, identifying an authority label for the consumer, the authority label being associated with transformation(s) to apply to messages, and based on obtaining a message from the publisher for publishing to consumers that are members of the service topology: determining that the consumer is a member of the service topology, identifying the transformation(s) based on the identified authority label for the consumer; applying to the message the transformation(s) to obtain a transformed message, and providing the transformed message to the consumer.

Abstract: A request is received to migrate a virtual instance from a source host compute node. The source host compute node is included in a distributed storage system environment. The virtual instance is migrated from the source host compute node to a first target host compute node. The first target host compute node has access to a first storage device. The first storage device includes one or more data units associated with the virtual instance. As part of the request to migrate the virtual instance, the one or more data units are migrated to a second storage device associated with the first target host compute node.

Abstract: Orchestrating flexible scaling for large scale deployment and elastic service of an application of a service model with an orchestration. The orchestration: analyzes input received from a user to generate feature references and a service definition of the application of the service model to be generated, extracts key features of the application of the service model from the feature references; analyzing the key features and service definition to generate a deployment configuration file with service dependencies required; and comparing the deployment configuration file to known strategy patterns. When a strategy pattern is not found that matches, analyzing the service definition and deployment configuration file to determine an applicable strategy pattern.

Abstract: A self-powered portable electronic device includes a main body, a cover slidably assembled on the main body, a sliding part secured on the cover, and a power generating device. The power generating device includes a rack secured on the sliding part, a power generating module assembled on the main body, and a gear engaging the rack and assembled on the power generating module. The cover slides the rack relative to the main body, and the gear is rotated by the rack and drives the power generating module to generate operating power.
