Consumption of data services provisioned in cloud infrastructures

A non-transitory machine readable medium storing one or more sequences of instructions, wherein execution of said one or more sequences of instructions by one or more processors contained in one or more servers causes said one or more servers to perform the actions of:

• maintaining a node-map data reflecting a corresponding set of nodes currently hosting each of a plurality of data services, wherein the corresponding set of nodes hosting a data service forms a universe for that data service;
• determining the performance of orchestration tasks, with each orchestration task designed to change the corresponding set of nodes hosting corresponding data services,
• wherein said orchestration tasks comprise at least one of expanding the universe, shrinking the universe, and migration of the universe,
• wherein expanding of the universe causes addition of at least one node to the corresponding set of nodes,
• wherein shrinking of the universe causes removal of at least one node from the corresponding set of nodes,
• wherein migration of the universe causes replacement of at least one node of the corresponding set of nodes with another node;
• updating said node-map data to reflect the changed set of nodes hosting each data service after performance of the corresponding orchestration task;
• receiving, from a consumer system, a resolution request containing an identifier of a first data service sought to be accessed;
• and
• sending identifiers of a first set of nodes currently hosting said first data service based on said node-map data such that said consumer system is provided identifiers of the changed set of nodes currently hosting said first data service.

A method performed by one or more servers, said method comprising:

• maintaining a node-map data reflecting a corresponding set of nodes currently hosting each of a plurality of data services, wherein the corresponding set of nodes hosting a data service forms a universe for that data service;
• determining the performance of orchestration tasks, with each orchestration task designed to change the corresponding set of nodes hosting corresponding data services,
• wherein said orchestration tasks comprise at least one of expanding the universe, shrinking the universe, and migration of the universe,
• wherein expanding of the universe causes addition of at least one node to the corresponding set of nodes,
• wherein shrinking of the universe causes removal of at least one node from the corresponding set of nodes,
• wherein migration of the universe causes replacement of at least one node of the corresponding set of nodes with another node;
• updating said node-map data to reflect the changed set of nodes hosting each data service after performance of the corresponding orchestration task;
• receiving, from a consumer system, a resolution request containing an identifier of a first data service sought to be accessed;
• and
• sending identifiers of a first set of nodes currently hosting said first data service based on said node-map data such that said consumer system is provided identifiers of the changed set of nodes currently hosting said first data service.
