Sharing data among different service providers at edge level through collaboration channels

A computer program product for sharing data among a plurality of service providers, the computer program product comprising a computer hardware readable storage medium having program instructions stored in the computer hardware readable storage medium, the program instructions readable by a collaborative computing system to cause the collaborative computing system to perform a method comprising:

• receiving a set of availability notifications from a set of central computing systems, the availability notifications indicating an availability of a producer computing system to share data of a shared category and of data categories of data available to the producer computing system;
• receiving authorization notifications from the set of the central computing systems, the authorization notifications indicating an authorization of a consumer computing system to receive the data of the shared category provided by a set of producer computing systems of a corresponding service provider;
• and
• establishing a set of collaboration channels among the set of producer computing systems and the consumer computing system authorized to receive the data of the shared category for use by producer computing system to provide the data of the shared category to the consumer computing system of a collaboration channel of the set of collaboration channels,
• wherein each of the producer computing systems encrypts data of categories to be shared with corresponding encryption keys and multicasts the data of the categories to be shared to all consumer edge servers of the collaboration channel and a record which comprises an identifier of a corresponding producer computing system and a digital certificate such that the data of the categories are shared among the consumer edge servers in a peer-to-peer (P2P) manner,
• each of the consumer edge servers verifies that the record has been provided by the corresponding producer computing system according to the digital certificate, and upon verification, decrypts the data of the categories, and
• the plurality of service providers comprise a plurality of cloud service providers providing a pool of cloud services implemented by virtual computing resources allocated upon request to users. 6302-40089

A computer system for sharing data among a plurality of service providers, the computer system comprising:
